Innovation of the Month: Project Bundling

Last week, we showed you how Idaho saved big with project bundling through economies of scale. This week, we’ll look at an Indiana Department of Transportation (INDOT) study that shows just how much that State saved using project bundling.

INDOT examined the effects of contract size and other factors on cost savings achieved by bundling. Researchers used nine years of data from nearly 2,000 bridge projects delivered through more than 700 INDOT contracts. The results confirmed and documented the benefits of bundling and produced models INDOT and other States can use to select the most appropriate projects to bundle in the future. The INDOT study investigated several factors affecting project bundling costs, including project size, bundle size, bidding market conditions, and similarity of bundled projects.

The study found that INDOT’s bundling efforts have saved them more than seven percent compared to historical non-bundled pricing. Some of the significant findings of the study include:

ECONOMIES OF SCALE: Unit costs declined as project size increased for all project types.

ECONOMIES OF BUNDLING: Cost per project went down as the bundle size grew. This was true for all bridge project types and for most traffic, small structure, roadwork and miscellaneous project types.

ECONOMIES OF COMPETITION: Having more bidders lowers costs for most bridge projects, but larger contracts can discourage small firms from bidding. According to the study model, the average number of bidders tends to be highest when two to four projects are bundled. INDOT monitors bids and developed rules to ensure that Disadvantaged Business Enterprise (DBE) program requirements were met. Bundles are created in ranges for all sizes of contractors.

PROJECT SIMILARITY: Project similarity within a bundle is an important factor for reducing project cost, especially for roadwork. Proximity also played a major factor, with projects less than 25-30 miles apart resulting in the best savings.

MAINTENANCE OF TRAFFIC (MOT) COST: Project bundling can generally reduce MOT cost for most road, traffic, bridge, and small structure work types. Of all work categories, roadwork benefits the most in terms of MOT cost savings.

The study recommends future bundling strategies including the use of statistical models to identify projects most suitable for combining into multiple-project contracts. In addition, patterns found in the study can be used to guide the number of projects selected for bundles and the findings can be used as a guide to support project scheduling decisions.

INDOT has developed business rules for bundling more strategically and earlier during project programming, allowing for greater economies of scale throughout project delivery. Based on bundling results, INDOT now assumes a significant annual savings, which can be put back into their budget for additional projects. With a developed process and data, INDOT is now piloting the use of machine learning to help automate bundle selections.

U.S. Transportation Secretary Elaine L. Chao Announces Key Resource for Rural Communities

WASHINGTON – U.S. Secretary of Transportation Elaine L. Chao today announced the Applicant Toolkit (Toolkit) for the Rural Opportunities to Use Transportation for Economic Success (ROUTES) Initiative at the U.S. Department of Transportation. It is the latest effort by the Department and the Trump Administration to improve rural access to federal grant funds. The Toolkit provides user-friendly information and resources to enhance rural applicants’ familiarity with the Department’s discretionary grant programs and the funding process.

“The ROUTES Applicant Toolkit will help rural communities better identify and navigate grant funding opportunities for rural transportation projects,” said U.S. Transportation Secretary Elaine L. Chao. 

Rural communities and their transportation networks have been instrumental in building and supplying urban areas throughout our nation’s history, carrying people from city to city and carrying freight from bedrock American industries such as agriculture, mining, forestry, and manufacturing. Yet rural transportation infrastructure has significant challenges.  

While one-fifth of Americans live in rural areas, 70% of America’s road miles are in rural areas, carrying nearly 50% of the nation’s truck traffic. In addition, 44% of automobile travel on rural roads is done by metropolitan area citizens, and rural America’s traffic fatalities are disproportionately high, with a fatality rate twice that of urban areas. Further, of the nation’s bridges that are posted for weight limits, 90% are in rural areas.

Discretionary grant applications can be complex and resource-intensive to complete. Many of the Department’s discretionary grant programs require non-federal funding to cover a portion of project costs, which may present an additional barrier to rural communities with limited funding. 

The new ROUTES Toolkit addresses these challenges by assisting rural stakeholders to better understand how to access the Department’s grants and financing products. Specifically, the Toolkit illustrates key applicant requirements when participating in the Department’s discretionary grants processes. It also catalogues discretionary grant programs by applicant type and eligible project activities. Additionally, the Toolkit provides resources for applicants to maximize the potential for award success.

Secretary Chao announced the ROUTES Initiative at the annual meeting of the American Association of State Highway Transportation Officials (AASHTO) in St. Louis, Missouri last October. The initiative is led by the ROUTES Council, an internal deliberative body at DOT, which identifies critical rural transportation concerns and coordinate efforts among the Department’s operating administrations.  

To learn more about the ROUTES Initiative and the Toolkit, visit www.transportation.gov/rural.

Innovation of the Month: Project Bundling

Last week, we showed you how several small municipalities in Georgia used project bundling to increase bid participation. This week, we’re going to focus on how bundling can use economies of scale to save time and money on projects.

In April 2016, The Idaho Transportation Department (ITD) was faced with the need to use surplus funds quickly. Bundling 17 bridges was identified as a method to use these funds. ITD selected 17 single-span bridges over canals and small rivers spread across three districts in Southeast Idaho.

ITD’s goals for these projects included minimizing impact to the traveling public, improving bridge geometry, accommodating ever-changing stream geometry, facilitating wildlife habitats, and enhancing access to nearby recreational and historic features.

The project team first met in August 2016, a contractor was selected in September 2017 and all 17 bridges were completed by October 2019. ITD estimates that the bridge projects would have taken 17 years had they not been bundled. This reflects large economies of scale in construction operations due to the bundles. Finally, as the final bid for the bundle came in $6 million below the engineers’ estimate, ITD realized significant cost savings as well.

The FHWA bridge bundling guidebook (pdf 19.5 mb) is an important resource for agencies to not only develop bridge bundling programs like the one in Idaho, but to learn the steps used in any bundling program.

For more information on Idaho’s bridge bundling program or to learn how your agency can use project bundling to gain economies of scale, contact Romeo Garcia with the FHWA Office of Infrastructure or David Unkefer with the FHWA Resource Center.   7/20

 

Innovation of the Month: Project Bundling

This month, we will showcase an advanced approach to project bundling that addresses the growing need to address aging infrastructure in a way that can expedite project delivery, reduce costs, and improve contracting efficiency.

Project bundling is not a new concept to transportation, but this advanced approach is built around 10-steps that improve the likelihood of success for these efforts. To take an in-depth look at these 10 steps, view the Bridge Bundling Guidebook (pdf 19.5 mb). Although the guide focuses on bridges, the information can be broadly applied to develop bundles that maximize agency resources on all types of projects.

A contract bundle’s scope can cover a single county, district, or State to address goals such as bridge and roadway repair and rehabilitation, reducing rural roadway departures, or improving pedestrian safety. Bundles can also be written to allow a combination of work types to best meet an agency’s specific needs.

Project bundling streamlines preconstruction activities such as environmental reviews and project design. If projects share features, agencies can use common design elements across the bundle. Addressing infrastructure needs in this way uses economies of scale to leverage design expertise, save procurement time, and reduce cost..

Pennsylvania’s Department of Transportation (PennDOT) conducted a three-county, $25 million pilot project that rebuilt, replaced, or removed 41 county-owned structures. This bundling effort resulted in a 25-50 percent savings on design and 5-15 percent savings on construction. The success of this effort led PennDOT to pursue a statewide, 558-bridge contract bundle.

To learn more about this practice, watch our Innovation Spotlight video or contact Romeo Garcia with the Federal Highway Administration Office of Infrastructure or David Unkefer with FHWA’s Resource Center for information, technical assistance, and training7/20

 

WSDOT Spawns Innovation at the National STIC Network Meeting

The Washington State Department of Transportation (WSDOT) Secretary of Transportation, Roger Millar, presented at the National STIC Network Meeting (Adobe Connect required to view video), April 23, 2020, on the innovative means WSDOT has undertaken to open up 90% of fish habitat by 2030. To meet this challenge, WSDOT incorporated the following innovations into their work plan:

  • Using project delivery approaches such as design build, progressive design build, accelerated bridge construction concepts and alternative construction materials.
  • Bundling of projects to maximize geographic locations and habitat benefits in a watershed.
  • Addressing regulatory requirements by providing liaison support between State and Federal agencies, programmatic approvals and early project coordination with Tribes and regulators.
  • Forming partnerships with adjacent land owners to remove barriers within the watershed more quickly.

WSDOT has seen costs savings and expedition of projects by using these innovations. WSDOT has also created partnerships with local and regulatory agencies that have improved over 300 miles of habitat access.

Innovation of the Month: Safe Transportation for Every Pedestrian

In 2018, an estimated 6,227 pedestrians died in the United States, according to the Governors Highway Safety Association—the highest total number of pedestrian fatalities since 1990. Pedestrian fatalities increased by 35 percent between 2008 and 2017, while other traffic fatalities decreased by six percent. The Safe Transportation for Every Pedestrian (STEP) program promotes seven proven countermeasures at pedestrian crossings to reduce growing numbers of pedestrian fatalities.

These countermeasures include:

In 2019, the City of Austin Transportation Department implemented Leading Pedestrian Intervals (LPIs) (pdf 312 kb) at 110 intersections in the Austin central business district to improve pedestrian safety in the City’s most active pedestrian environment. The effort required collaboration between City’s Vision Zero Program staff, traffic signal engineers, and public information personnel. The project was not labor intensive for staff to complete; three City engineers implemented the LPIs over 4 hours during December 2019, using remote communication with the traffic signals. The City then set all of the LPIs to 5 seconds after reviewing operations. 

The City received overwhelmingly positive feedback from the public following implementation, and is continuing to monitor pedestrian safety effects. The City conducted an intercept survey of 166 pedestrians in downtown Austin, and 87 percent of respondents agreed or strongly agreed that they felt safer crossing at an intersection knowing they had a head-start due to the LPI. Furthermore, 60 percent agreed or strongly agreed that they are more likely to use a crosswalk knowing that it has an LPI.

STEP Resources:

The FHWA Guide for Improving Pedestrian Safety at Uncontrolled Crossing Locations (pdf 6.8 mb) details a six-step process to help agencies select countermeasures for uncontrolled crossing locations.

FHWA published 18 STEP Case Studies that highlight State and local agency practices, policies and decision-making strategies for deploying the STEP countermeasures. The case studies include installation examples with measured impacts on pedestrian safety, and practices where State DOTs integrated pedestrian safety and countermeasures into Complete Streets policy, transportation plans, and data analysis.

A set of six STEP Countermeasure Tech Sheets is also available, describing each STEP countermeasure promoted for uncontrolled crossing locations. Each tech sheet includes an illustration, cost information, design considerations, and crash reduction factors.

Finally, six STEP Countermeasure Videos are available to explain the overall purpose and design elements for STEP countermeasures. These animated videos will help educate a broad spectrum of officials and the public. You can use these videos to engage audiences at conferences, public meetings, and through other digital communications.   5/20

WYDOT Adds Feature to Mobile App to Push Crowdsourced Data to Public

The Wyoming Department of Transportation (WYDOT) developed a hands-free mobile app for reporting conditions on and off highways statewide. The app allows citizens and WYDOT staff to submit text and images, which are geo-located and sent to the traffic operations center for verification.

Once verified, the system now has a backend feature that allows the information to be automatically pushed back to app users as well as to the 511 traveler information website. This ability will help WYDOT identify appropriate resources and reduce response times and the potential for secondary crashes. To further enhance communications, WYDOT is also developing a prototype function to alert emergency managers automatically in each county of relevant crowdsourced reports.

To learn more about how crowdsourcing can help your State develop innovative practices such as these, contact James Colyar or Paul Jodoin with the FHWA Office of Operations.   4/20

 

Caltrans Improves Local Road Safety

In California, over 800 people die each year due to a roadway departure on a rural road. That is more than two people lost every day. Over 60 percent of these occurred on local roads. The California Department of Transportation (Caltrans) is moving FoRRRwD by dedicating $10 million of their safety funding for local agency roadway safety improvements. For agencies to obtain the funding, the state requires a Local Road Safety Plan (LRSP) in future funding cycles that identifies a 4E approach (engineering, education, enforcement, and emergency medical services) to local agencies’ safety priorities.

Working with Caltrans, FHWA provided comprehensive training to five counties to develop LRSPs. Now, those counties are assisting other counties in the state by sharing their successes and lessons learned through peer exchanges and statewide webinars. Together, this outreach and technical assistance has reached hundreds of local agency officials to assist them with making roads safer and reducing the risk and number of fatal and injury crashes.

The Focus on Reducing Rural Roadway Departures (FoRRRwD) team is here to help provide technical assistance in your State. To learn more about how your agency can receive technical assistance, contact EDC-5 FoRRRwD team leads Cate Satterfield or Dick Albin.   4/20

 

Don’t Miss the First EDC Storyboard- Telling the Story of Curve Warning Signs

The EDC team will begin sharing innovation deployment stories in an interactive digital slideshow, that incorporates images, video, and graphics to create a highly visual experience for our readers.

Our first storyboard, Curve Warning Signs Save Lives, comes from the focus on reducing rural roadway departures (FoRRRwD) team and promotes greater use of curve warning signs. More than 36,000 people die each year on the nation’s highways. Over 25 percent of those fatalities occur on horizontal curves—curves that change a road’s direction or alignment. Curve warning signs, such as chevrons, are cost-effective tools proven to reduce horizontal curve crashes. For instance, chevrons reduce nighttime crashes on curves by 25 percent.

For more information on using curve warning signs on your roadways, contact Cate Satterfield or Dick Albin with the EDC FoRRRwD team.   4/20

FoRRRwD Begins Monthly Webinar Series on April 16

FHWA has been working with State DOTs and local agencies to reduce roadway departure (aka lane departure) crashes since the inception of the Focused Approach to Safety in 2004.  Even so, nearly 12,000 people die every year in the U.S. in lane departures on rural roads - that's 30 people every day. The current FHWA Focus on Reducing Rural Roadway Departures (FoRRRwD) emphasizes four pillars in its mission:

  • Address all public roads
  • Use a Systemic Approach
  • Develop a Safety Action Plan
  • Install Proven Safety Countermeasures

Webinar Series based on Pillars

This webinar series, which is a collaborative effort between the FHWA, the National Center for Rural Road Safety, and the National Local Technical Assistance Program Association (NLTAPA) Safety Workgroup, will cover all four pillars.  The pillars work together, but each webinar will highlight a specific pillar.

The first two webinars, scheduled for April 16 and May 12, cover the first pillar.  They will show how some States and local agencies have evaluated safety data to identify projects that reduce lane departures.  Additionally, they will highlight how these agencies have funded development of local road safety plans (LRSPs) and projects based on those plans, including contracting mechanisms to deliver the projects. FHWA also plans to host a related webinar shortly after this that features a related topic - bundling safety projects.

The next few webinars will accentuate the systemic approach to FoRRRwD and why it is critical to addressing these crashes that never seem to happen in the same place twice. The FoRRRwD Team hosted a webinar that underscored this in May 2019. The follow-up webinars will include risk factors specific to rural roadway departures, tools to use in systemic analysis, and prioritizing locations.

Roadway departure countermeasures will be grouped for audiences. For instance, high-friction surface treatments, SafetyEdgeSM, and rumble strips will likely be covered in one webinar since they all relate to the pavement surface, while traffic control treatments such as signing and striping would be the topic of another webinar.

Since the Rural Road Safety Centers recently had two webinars on LRSPs, the FoRRRwD webinars on Safety Action Plans will be held near the end of the series and will complement the previous webinars, both broadening the potential range of plans beyond local agency specific plans, and narrowing the focus to plans that primarily address rural lane departure.

All the webinars will be free to everyone, so please join us and help us save the people behind the numbers!

April 16 Webinar Details

FoRRRwD on All Public Roads: Funding and Data to Identify Projects.

UAS Soar to Savings with Sign Inspections

The Utah Department of Transportation (UDOT) uses Unmanned Aerial Systems extensively in programs across the State. UDOT has the majority of its bridge inspectors FAA certified to operate UAS and has several members of maintenance staff certified to conduct sign inspections, snow depth analysis, and asset inspections.

Before UAS, overhead sign inspections were a time consuming process. These inspections, which look for missing rivets and bolts after installation, could only cover two to three signs per day with traditional methods and required additional traffic control to protect department personnel. By contrast, in one project assessing signs on State Route 201 and I-80, UAS enabled UDOT inspectors to complete up to 16 inspections per day, saving over $100,000 through productivity increases and reduced needs for traffic control.

To learn more about how UAS can save your agency time and money, contact James Gray, FHWA Office of Infrastructure.   3/20

 

FHWA and ITE Partner to Provide Training to Local and Tribal Transportation Practitioners

Washington, DC -- Through an agreement with the Federal Highway Administration (FHWA), ITE will provide free web-based training modules to local and tribal public agency practitioners in smaller jurisdictions (counties with fewer than 100,000 population; cities, towns and townships with fewer than 50,000 population; all tribal governments) through the ITE Learning Hub. This training, geared toward local agency and tribal government highway maintenance, construction, safety and engineering staff and managers as well as others, will involve numerous critical transportation areas, including transportation fundamentals, intelligent transportation systems (ITS), traffic engineering, and safety.

The goal of this training is to provide local and tribal transportation practitioners with the knowledge to meet the challenges faced by greater mobility and expanded population. Across the United States, there are more than 39,000 local governments and 573 federally recognized tribes that own and operate more than 80 percent, or roughly 3.3 million miles, of our nation’s highway network.

To be eligible, transportation professionals must be employed by a public agency:

  • in a county with fewer than 100,000 inhabitants;
  • in a city, town, or township with fewer than 50,000 inhabitants; or
  • that is part of a tribal government.

"It is important to ITE that all transportation professionals – regardless of community size – have access to the necessary training and education to improve the quality of life in their communities," stated ITE’s Executive Director and CEO, Jeffrey F. Paniati. P.E. "We are very pleased to partner with FHWA to share our expertise."

Local roads provide critical connections that allow people and goods to move about communities, neighborhoods, and towns. All these organizations share similar unmet needs in managing their networks and require assistance in capacity building and implementation of innovation.

These training modules will offer access to information about foundational and emerging technologies and practices to help these professionals move beyond the status quo and identify new ways of looking at problems and the use of both proven and innovative solutions. There will be no charge for access to these training modules.

To learn more and to confirm eligibility, please contact Kellyanne Broom, ITE Professional Development Manager, at pdinfo@ite.org.

EDC-5 Synergies

The Washington State Department of Transportation (WSDOT) is demonstrating how combining EDC innovations accelerates success.  The WSDOT Visual Engineering Resource Group (VERG) combines Virtual Public Involvement (VPI) and Unmanned Aerial Systems (UAS) to enhance the transportation decision making process.

VERG provides clear and effective communication of project development, design, and delivery issues through visual media made with a wide range of 3D modeling, animation, video, and other graphic software packages. From planning and communication to design and construction, VERG products are vital to project success.

VERG uses aerial video in many of their products, and WSDOT credits UAS with reducing lead-time and cost. Purchasing a UAS system can be a similar price as a few hours of helicopter rental, and the UAS provides years of service.  VERG uses the UAS to recreate cinematic shots and effects in their visual storytelling of a project.

To support public involvement for one of the most complex projects in WSDOT’s history, VERG used drones to capture footage of key stages of the Alaskan Way Viaduct’s construction process to provide public updates through web links, public meetings, and social media, including their YouTube channel.

In the City of Bingen, WA, VPI and UAS came together in another project, where a roundabout was being proposed. VERG combined aerial video with 3D modeling to create a combined view, visualizing what the project would look like once complete. This visualization was able to clearly explain the project to stakeholders including local government officials and businesses, which helped generate support for the project while avoiding potential delays.

To find out how VPI can help your agency expand its outreach, contact Scott Allen, FHWA Office of Planning, or Carolyn Nelson, FHWA Office of Project Development and Environmental Review. For more information on UAS, contact James Gray, FHWA Office of Infrastructure.   12/19

New Jersey, Pennsylvania, and Washington Win STIC Excellence Awards

State Transportation Innovation Councils (STIC) in New Jersey, Pennsylvania, and Washington received 2019 STIC Excellence Awards for demonstrating success in fostering a strong culture of innovation. The American Association of State Highway and Transportation Officials (AASHTO) and Federal Highway Administration collaborate on the annual award, which was presented to the winning STICs at AASHTO’s annual meeting in St. Louis, MO.

New Jersey

The New Jersey STIC is developing a culture of innovation with broad stakeholder participation, shared metrics, and an engaged leadership. The STIC established processes to identify and move new technologies into practice, including an online portal to solicit potential ideas. The STIC also created three teams—Infrastructure Preservation, Safety, and Mobility and Operations—to champion innovations. A new web page features information on the STIC’s innovation initiatives and a searchable innovation database.

Pennsylvania

The Pennsylvania STIC fosters an innovative culture at all levels of government and throughout the private and nonprofit sectors to ensure smart investments in Pennsylvania's highway infrastructure. The STIC consolidated its Technical Advisory Groups from 10 to four—Design, Construction and Materials, Maintenance, and Safety and Traffic Operations—to improve efficiency, enhance collaboration between groups on overlapping innovations, and provide flexibility to engage a variety of subject matter experts. The STIC also revamped its website, which features innovation deployment information and an interactive Year-End Report.

Washington

The Washington STIC is building a culture of innovation through collaboration to update the Washington State Department of Transportation Hydraulics Manual and to develop a programmatic biological assessment with the U.S. Fish and Wildlife Service. These efforts brought local, Federal, and private sector partners to the table to look at how to institutionalize innovations statewide.

Innovation of the Month: Safe Transportation for Every Pedestrian

FHWA’s Guide for Improving Pedestrian Safety at Uncontrolled Crossing Locations (pdf 6.81 mb) details a six-step process to help agencies select countermeasures for uncontrolled crossing locations based on research and best practices.

The Pedestrian Safety Guide and Countermeasure Selection System (PEDSAFE) Countermeasure Selection Tool responds to user input and returns a list of STEP countermeasures suitable to the roadway conditions. For each countermeasure, PEDSAFE provides users details about typical costs, design considerations, and installation examples.

The STEP Countermeasure Tech Sheets describe countermeasures for uncontrolled crossing locations and provide detailed information on cost and crash reduction factors. A set of STEP Countermeasure Videos is also available to explain the overall purpose and design elements for several of these countermeasures. These materials emphasize the life-saving impact of the STEP countermeasures to state and local transportation agencies.

States are already using these resources to develop and implement plans of their own across the country.

Pedestrian fatalities continue to rise across the nation and in Arizona. To combat the increase, the Arizona Department of Transportation (ADOT) formed a multi-agency team including ADOT, FHWA, the City of Phoenix, City of Tempe, and City of Tucson to advance implementation of STEP countermeasures. The STEP team referenced the Statewide Pedestrian Safety Action Plan (2017) (pdf 24.7 mb) to help identify locations for focused improvements. The team also identified the different challenges that rural and urban areas face with implementing the STEP countermeasures and designed resources to help local agencies advance STEP on locally owned road systems.

The team developed an AZ STEP Guide website devoted to their program, including an interactive countermeasure selection tool based on FHWA guidelines. The website provides links to Arizona-specific installation examples, illustrations of the countermeasures, and references to State laws and MUTCD guidance for the design of the treatments.

To learn more about the STEPs you can take to choose and implement countermeasures, please contact Becky Crowe with the FHWA Office of Safety or Peter Eun with the FHWA Resource Center.   10/19

 

FHWA Final Rule Encourages Innovation in Federally Funded Highway Projects

On September 27, 2019, FHWA issued a Final Rule (pdf 334 kb) in the Federal Register repealing the long-standing federal provisions (23 CFR 635.411(a)-(e)) for the use of patented or proprietary products on federal-aid projects; this rule will take effect on October 28, 2019.  The Final Rule provides to the states the flexibility to use their procurement procedures when deciding the selection of proprietary or patented materials.   10/19

 

Innovation of the Month: Safe Transportation for Every Pedestrian

In 2018, an estimated 6,227 pedestrians died in the United States, according to the Governors Highway Safety Association– the highest total number of pedestrian fatalities since 1990. Pedestrian fatalities increased by 35 percent between 2008 and 2017, while other traffic fatalities decreased by six percent. The Safe Transportation for Every Pedestrian (STEP) program promotes proven countermeasures at pedestrian crossings to reduce growing numbers of pedestrian fatalities.

The seven countermeasures include: crosswalk visibility enhancements, raised crosswalks, refuge islands, Rectangular Rapid-Flashing Beacons (RRFBs), Pedestrian Hybrid Beacons (PHBs), Road Diets, and Leading Pedestrian Intervals (LPIs).

Over the next four weeks, we will look at four features of implementing STEP. They include the system— considering all pedestrian crossings and the risk factors that contribute to crashes and fatalities; the tools—countermeasures selected to increase pedestrian safety at a given location; evaluation—verified results in areas implementing STEP can lead to further implementation, and people—partnerships formed between agencies and the integration of law enforcement and public education into your pedestrian safety efforts.

STEP Resources:

The FHWA Guide for Improving Pedestrian Safety at Uncontrolled Crossing Locations (pdf 6.8 mb) details a six-step process to help agencies select countermeasures for uncontrolled crossing locations.

FHWA published 18 STEP Case Studies that highlight State and local agency practices, policies and decision-making strategies for deploying the STEP countermeasures. The case studies include installation examples with measured impacts on pedestrian safety, and practices where State DOTs integrated pedestrian safety and countermeasures into Complete Streets policy, transportation plans, and data analysis.

A set of six STEP Countermeasure Tech Sheets is also available, describing each STEP countermeasure promoted for uncontrolled crossing locations. Each tech sheet includes an illustration, cost information, design considerations, and crash reduction factors.

Finally, six STEP Countermeasure Videos are available to explain the overall purpose and design elements for STEP countermeasures. These animated videos will help educate a broad spectrum of officials and the public. You can use these videos to engage audiences at conferences, public meetings, and through other digital communications.

Watch and share our innovation spotlight video for STEP, and to learn how your State can STEP up its pedestrian safety efforts, contact Becky Crowe with the FHWA Office of Safety or Peter Eun with the FHWA Resource Center.   9/19

 

Innovation of the Month: Focus on Reducing Rural Roadway Departures

Over the last few weeks, we have discussed the four pillars of the focus on reducing rural roadway departures (FoRRRwD) initiative—addressing roadway departures on all public roads, using systemic safety analysis to identify those locations most at risk, developing safety action plans, and implementing proven roadway departure countermeasures.

This week, we showcase Washington State, who worked with its local agencies to use all four pillars of FoRRRwD to effectively prevent lane departure crashes.

The State evaluated the location of fatal and serious collisions, and dedicated 70 percent of their Highway Safety Improvement Program (HSIP) funding to local agency projects—putting the money where the problems were.

Washington State determined 70 percent of its fatal and serious collisions occurred on local roads. They dedicated a matching 70 percent of HSIP funding to local roadways to combat this problem.

The State conducted initial data analysis and provided information to county engineers for their own county-level systemic analysis. The crash and roadway data allowed each county to easily compare itself to similar counties based on a number of risk factors. Thirty-five of 39 counties completed local road safety plans (LRSPs) to establish priorities and qualify for HSIP funding.

In Thurston County, where about two-thirds of the roads are in rural areas, officials used systemic analysis and its LRSP to target horizontal curves. These curves accounted for 45 percent of the county’s fatal and serious injury crashes from 2006 to 2010. With HSIP funding, Thurston County implemented curve safety countermeasures such as enhanced signing, raised pavement markers, rumble strips, and guardrail delineation.

As a result, fatal and serious injury crashes on horizontal curves in Thurston County decreased by 35 percent from 2012 to 2016.

Innovation of the Month: Focus on Reducing Rural Roadway Departures

During the month of September, we are discussing the four pillars of the focus on reducing rural roadway departures (FoRRRwD) initiative—addressing roadway departures on all public roads, using systemic safety analysis to identify those locations most at risk, developing safety action plans, and using proven countermeasures to reduce lane departures.

Once an agency has identified at-risk locations with systemic analysis and developed a safety action plan, it must implement roadway departure countermeasures to achieve crash reductions. There are many lane departure countermeasures to consider, including those in the Proven Safety Countermeasure Initiative. It is important to understand the three objectives that these safety treatments seek to achieve.

Transportation agencies are encouraged to use 18 trading cards illustrating rural roadway departure crash types, countermeasures and tools in their own meetings to educate staff on various approaches to reduce rural roadway crashes. Click on the image to download a printable PDF.

Objective 1: Keep vehicles on roadways and in their lane. Signing, pavement markings, friction treatments, and rumble strips are countermeasures that help achieve this objective. In a study analyzing data from Minnesota, Pennsylvania, and Washington State, centerline rumble strips on two-lane rural roads reduced head-on injury crashes by 38-50 percent.

Objective 2: Increase the opportunity for safe recovery. Shoulders, traversable slopes, clear zones, and SafetyEdge℠—a paving technique that provides a safe transition back onto the pavement, are examples of this objective in practice. In a study including Iowa, North Carolina, Ohio, Pennsylvania, and one Florida county, SafetyEdge℠ reduced all injury crashes by 11 percent.

Objective 3: Reduce crash severity. Barriers and breakaway designs for signs, luminaires, and mailboxes are examples of these types of countermeasures. Cable barriers, for example, are a flexible barrier that reduces crash severity. They are most commonly seen as a median barrier on divided highways, and are being used as roadside barriers on two-lane roads in South Dakota, New York, and Colorado. Cable barriers are particularly effective on the outside of curves, where run-off-road crashes are most common.

National Roundabouts Week

Each year, during the third week in September, FHWA celebrates National Roundabouts Week to raise awareness about this safe and efficient intersection design. Modern roundabouts reduce severe crashes by approximately 80 percent (pdf 245 kb) compared to traditional two-way stop-controlled intersections.

Roundabouts are effective in urban and rural areas under a wide range of traffic conditions. Today, there are more than 4,000 modern roundabouts in the United States.

FHWA encourages transportation agencies to consider roundabouts during new construction and reconstruction projects, as well as for existing intersections identified as needing safety or operational improvements. There's no way around it-roundabouts are an effective safety countermeasure.

Join the conversation on social media using the hashtag #RoundaboutsWeek..   9/19

 

MassDOT Making Bus Routes Safer for Pedestrians

As part of its effort to integrate pedestrian safety countermeasures into Massachusetts policies, plans, and projects, MassDOT is looking at ways to make systemic improvements to pedestrian crossings along bus routes, beginning in the City of Chelsea.

As part of a pedestrian safety study, Chelsea inventoried pedestrian accommodations at bus stops. Looking at the highest volume stops, MassDOT compared pedestrian-related crashes and the physical conditions of the stops and then conducted road safety audits for Chelsea’s bus corridor to identify potential pedestrian crossing improvements, bus stop improvements, and roadway changes to reduce pedestrian-vehicle conflicts.

The City is currently developing a preferred corridor design with safety enhancements, scheduled for completion in late 2019.

The State is evaluating using this process as a model for how to improve pedestrian safety on roadways with bus routes.

To learn more about MassDOT’s effort to improve pedestrian safety along bus routes, please contact Kevin Fitzgerald with MassDOT or Michael Pezzullo with the FHWA Massachusetts Division.   9/19

 

Innovation of the Month: Focus on Reducing Rural Roadway Departures

Last week, we discussed two of the four pillars of the focus on reducing rural roadway departures (FoRRRwD) initiative—recognizing that roadway departures happen on all public roads and using systemic safety analysis to identify those locations most at risk.

The next pillar involves taking those identified locations and developing strategies to address them in a safety action plan. These plans, whether simple or complex, are a powerful, data-driven way to prioritize safety activities and improvements and justify your investment decisions. A formal plan helps to communicate your priorities to other stakeholders including elected officials and the public, and may help secure any necessary funding. Last week we highlighted County Road Safety Plans in Minnesota, but any type of road agency can create Local Road Safety Plans (LRSPs).

The planning process has some key steps, obtaining stakeholder input, using crash and roadway data, and choosing proven solutions to implement. This process is scalable and can be modified for any level of available data and expertise. Data is critical to the plan, but lack of data shouldn’t prevent an agency from developing one. For instance, if traffic volumes aren’t available, agency staff can categorize the roads into low, medium and high volume. If roadway departures are occurring on curves for which geometric information is not available, a map can quickly help identify the sharpest curves or other areas that may require attention. Law enforcement, public health officials, and roadway maintenance staff are a great resource for this type of data.

This Local Roads Safety Plan video shows the overall steps to develop a Local Road Safety Plan.

In California, Caltrans piloted a project with five counties to develop LRSPs. When these pilot counties apply for Highway Safety Improvement Program (HSIP) funds, Caltrans can be confident these are data-driven safety projects. Caltrans is considering an approach which will require a local agency to have an LRSP or equivalent plan to qualify for HSIP funding.

Next week, we will look at some proven countermeasures for reducing roadway departures.

Bundling Helps Improve System Performance

Did you know project bundling has proved to be a valuable tool in all three major approaches to managing bridge condition and performance: preservation/preventive maintenance, rehabilitation, and replacement? It allows agencies to strategically focus resources and increase return on investment as they improve system-wide performance and safety.

The New York State Department of Transportation (NYSDOT) is combining the preservation needs of eight eastern counties into three project bundles, one each for preservation, painting and washing. NYSDOT also bundled 81 deck replacement projects into 9 bundles, improving the efficiency of program delivery. In total, NYSDOT replaced 116 bridge decks in two years using bundling.

Read FHWA’s Bridge Bundling Guidebook (pdf 19.5 mb) for case studies on these programs and others. For technical assistance, contact Romeo Garcia, FHWA Office of Infrastructure, or David Unkefer, FHWA Resource Center.   9/19

 

Focus on Reducing Rural Roadway Departures

Thirty people will die today, and every day, in a rural roadway departure—accounting for one third of U.S. traffic fatalities. The Focus on Reducing Rural Roadway Departures (FoRRRwD) EDC initiative aims to provide technical assistance and training to States, counties, parishes, townships, and other local agencies across the country to address this deadly problem. This is accomplished through FoRRRwD’s four pillars.

The first pillar is recognizing that roadway departures happen on all public roads. Up to half of roadway departure deaths happen on locally-owned roads, off the State highway system. This is why the FoRRRwD initiative puts emphasis on helping both local and State agencies.

Another pillar of FoRRRwD is systemic safety analysis to identify locations for safety improvement. The systemic approach identifies locations that are at high risk of serious rural roadway departure crashes. The analysis is based on roadway features that correlate with particular crash types. Then agencies can install countermeasures at multiple locations across the system with those higher-risk features. Essentially, historic crash and roadway data help agencies identify locations with the greatest potential for future crashes. Because roadway departures are scattered across the rural network, the systemic approach is essential, as it involves widely implemented low cost improvements.

Narrowing down probable crash locations and implementing countermeasures, sometimes even before crashes occur, allows agencies to improve rural road safety in a proactive way.

The Minnesota Department of Transportation (MnDOT) used systemic safety analysis as it developed road safety plans for each of the State’s 87 counties. Using a process similar to that outlined in the systemic safety project selection tool, MnDOT helped identify high-risk locations in each county. The analysis also identified emphasis areas to significantly reduce the severe and fatal crash types and helped compile a list of potential safety countermeasures. Ultimately, this information helped counties identify low-cost safety projects to implement on a systemic basis, a key objective of the road safety plans.

Next week, we will discuss how to use the results of systemic analysis to develop safety action plans, the third pillar of FoRRRwD.   8/19

 

Leading Pedestrian Intervals Key to Pedestrian Safety in the District

The FHWA Safe Transportation for Every Pedestrian (STEP) program promotes leading pedestrian intervals (LPIs) as a proven safety countermeasure for pedestrians crossing at signalized intersections. LPIs allow pedestrians to walk—usually 3 to 5 seconds—before vehicles receive a green signal to turn left or right.

The District Department of Transportation (DDOT) in Washington D.C, is implementing LPIs across their network. Starting in 2018 with the Citywide Signal Optimization program, DDOT developed selection guidelines and criteria where intersections could be evaluated quickly for LPI implementation. These guidelines capture the magnitude and severity of pedestrian-vehicle interactions at signalized intersections, and identify locations where the physical characteristics of the intersection make those interactions more dangerous.

The data used to drive these decisions includes crash data, pedestrian and vehicle volume counts, land use, and a visual inspection of sight line obstructions and crosswalk locations.

Under DDOT's program, every signal in the city will be evaluated for LPI implementation by the end of the current five-year cycle. Last fall, DDOT implemented approximately 90 new LPIs, bringing its total to over 330. This year, it expects to implement over 250 new LPIs as they maintain their commitment to Vision Zero.

Is your agency considering widespread installation of LPIs? If so, please contact Becky Crowe of the FHWA Office of Safety or Peter Eun of the FHWA Resource Center.   8/19

 

Washington Virtually Engages Public on First Diverging Diamond Interchange

The Washington State Department of Transportation (WSDOT) launched a virtual public involvement (VPI) initiative to inform the public on what to expect from its first diverging diamond interchange (DDI).

The State’s visual engineering resource group (VERG) used three-dimensional modeling to create a virtual representation of the project and how it could impact drivers and pedestrians. WSDOT then captured public opinion on various aspects of the proposed model through the use of online polling.

A video of the project, “Diverging Diamond Interchange Comes to Washington State,” was a valuable tool to describe the project and its benefits in high volume interchanges to improve safety and efficiency. The video has more than one million views, indicating the VPI initiative was successful at reaching a wide audience of stakeholders.

WSDOT officials believe this project provides an example of how other States can incorporate VPI into projects. For more information on how Washington incorporated VPI in this project, contact Kurt Stiles with the WSDOT VERG.   8/19

 

Unmanned Aerial Systems

Unmanned aerial systems (UAS), or drones, transform highway transportation by enhancing safety and productivity and reducing cost.

North Carolina uses UAS in construction inspection to routinely monitor and document large and complex construction projects. Source: North Carolina DOT

During August, we will give you examples of UAS deployment in three major categories— structural inspection, construction inspection, and emergency response— and show the benefits agencies using UAS are already seeing.

  • In structural inspection, UAS improve safety for inspection teams and the traveling public by reducing the need for temporary work zones.
  • In construction inspection, UAS provide data for surveying, project scoping, quantity verification, and work zone traffic monitoring.
  • In emergency response operations when roadways are impacted and difficult to access, UAS allow agencies to make informed decisions in response to rockslides, avalanches, floods, earthquakes, fires, severe storms, and other emergency events.

To learn more about UAS and how they are changing the way transportation agencies do business, visit FHWA’s UAS website. If you would like to learn how to deploy UAS in your State, please contact James Gray with the FHWA Office of Infrastructure or John Haynes of the FHWA Utah Division.   8/19

 

How Many Bridges to Bundle?

How Many Bridges to Bundle?

When it comes to project bundling, there is no one-size-fits-all approach. States have successfully used bridge bundles ranging from 2 to more than 500.

  • Missouri replaced or rehabilitated 802 bridges over 3.5 years using a single contract for 554 bridges and smaller bundles for the remainder.
  • Georgia accelerated the replacement of 25 local bridges using 5 bundles with 4–6 bridges each, based on location.
  • Pennsylvania is replacing 558 State bridges in under 3 years in a single public-private partnership procurement. The State also offers a local agency program that bundles bridges with similar designs into smaller contracts.

Learn about the criteria used to determine bundle size and select projects for these programs and others in FHWA’s Bridge Bundling Guidebook (pdf 19.5 mb). For details, contact Romeo Garcia, FHWA Office of Infrastructure, or David Unkefer, FHWA Resource Center.   8/19

 

Colorado Uses Friction Sensors to Increase Safety and Lower Costs

The Colorado Department of Transportation (CDOT) is using friction sensors— electronic radars attached to the back end of fleet vehicles— to collect data on the amount of grip present on a roadway, increasing road safety and lowering costs. The sensors relay information on pavement temperature changes, along with friction and moisture levels present on a roadway, to the Maintenance Decision Support System (MDSS) where they determine which segments of roadway need salt, liquid materials, plowing, or a combination of treatments. By mapping site-specific data, maintenance workers can focus on areas that need treatment rather than treating whole sections of roadway.

In testing these sensors on a small selection of roads, CDOT reduced use of solid materials by 21 percent and liquid materials by 56 percent over the course of three statewide snowstorms. These reductions resulted in $180,000 of savings in material costs for CDOT. If implemented State-wide, CDOT estimates these sensors will save over a million dollars per year with the State’s average 15 snowstorms per winter.

The program’s success has resulted in its expansion, with the State expecting to have 70-80 mobile sensors in the field by the end of winter, 2019-2020. To learn more about road weather management – weather-savvy roads, contact Ray Murphy of the FHWA Resource Center.   7/19
