CTS Webinar: How Infrastructure Shapes Driver Behavior and Pedestrian Safety

About the Event 

Improving pedestrian safety requires a deeper understanding of how people interact with roadway design and infrastructure. This webinar will highlight two recent research efforts examining how transportation infrastructure influences driver behavior and pedestrian safety outcomes.

Curtis Craig, a research associate in the Human Factors Safety Laboratory, will present findings from two complementary studies examining infrastructure at intersections. The first study explored how right turn lane configurations affect pedestrian safety using a combination of behavioral analysis and multiple research methods. The second project examined how drivers and pedestrians respond to different infrastructure treatments and how those designs influence behavior in real-world environments.

These study findings offer transportation agencies, planners, and engineers practical considerations as they work to create safer and more accessible pedestrian environments.

Addressing disparities through more equitable transportation planning

Reprinted from CTS Catalyst April 16, 2026

Transportation capital investment planning plays a vital role in shaping the future of infrastructure—but often leaves people with disabilities, youth, older adults, people of color, and disadvantaged communities underserved. A recent UMN research project aimed to gain a better understanding of how to include equity in planning and decision making.

To gain a better understanding of how to include equity in planning and decision making, a recent research project explored this complex topic through a literature review, statewide survey, and analysis of case studies. This research, sponsored by the Minnesota Department of Transportation (MnDOT) and the Minnesota Local Road Research Board, resulted in considerations and strategies, including a toolkit, to increase community engagement and guide future transportation development for Minnesota localities and Native nations.

Camila Fonseca-Sarmiento, director of fiscal research for the Institute for Urban & Regional Infrastructure Finance at the University of Minnesota’s Humphrey School of Public Affairs and a CTS scholar, led a team of researchers through a review of case studies for which equity was included in capital investment planning. As in other states and localities across the United States, the team found that the definition of equity and the goals of equity-related funding ranged widely across Minnesota’s counties, cities, and Native nations.

Incorporating equity factors in transportation investment planning in Minnesota has occurred through small, incremental changes. A few jurisdictions have already integrated equity into their planning efforts, while some others are in the process of doing so. Jurisdictions with a more comprehensive equity framework are those in which equity is part of a local initiative, compared to those who mentioned equity efforts as a response to federal funding requirements, such as Title VI of the Civil Rights Act of 1964 and the Americans with Disability Act.+6

Minnesota brings an additional set of equity considerations through the inclusion of the state’s 11 Native nations. These Ojibwe and Dakota communities and reservations share many of the same needs and challenges as other localities but also possess unique cultural considerations, including sovereignty, sacred sites, and environmental protection. For example, on a practical level equity for Native nations means fair employment—equitable job opportunities, wages, and hiring preferences for tribal members to ensure benefits stay within the tribal nations on or near reservations. On a cultural level it means dual language signage for English and Ojibwe or Dakota on roads and highways that traverse Native lands.

“Equity is not a one-size-fits-all approach,” Fonseca-Sarmiento says. Engaging community members early in the planning process helps planners understand transportation needs beyond roadway investments—such as a community’s historical experience, culturally specific needs, and current gaps. The research findings offer guidance on how to gather local input through surveys and in-person meetings guided by trained staff. 

The transportation capital investment planning and decision-making process consists of several phases where equity could be integrated: identifying projects, prioritizing capital investment projects through multi-step processes, and selecting projects for funding through community advisory committees.

A toolkit developed by the researchers could help improve communication and engagement with underserved communities. Its two key tenets are that agencies need to proactively reach out to the community, and trust-building is essential for effective relationships.

In addition, Dillon Dombrovski, deputy public works director/city engineer with the City of Rochester and the project’s technical liaison, says the community engagement toolkit “provides effective guidance to combine community input with supporting data to invest in more equitable transportation projects.”

Fonseca-Sarmiento says it’s also critical to listen and then include diverse perspectives in the final transportation plan. “Engaging local stakeholders in the planning process but then leaving them out of the finished project decreases trust and limits future engagement,” she says. “Overall, having regular community engagement for identifying transportation capital investment projects can also help prevent perpetuating past inequities.”

Alerting Drivers Dangerously Approaching Work Zones

Motorists driving dangerously in work zones present a safety risk to workers and themselves. Alerting these drivers about their driving behavior before they reach the work zone could reduce the number of work zone crashes and enhance work zone safety. This project developed and evaluated the performance of a device that provides audio and visual alerts to drivers whose vehicles are approaching work zones at a high speed and on a dangerous trajectory.

Evaluating the Safety Impacts of Select Pedestrian Infrastructure

To enhance pedestrian safety at intersections, transportation agencies may install temporary or permanent infrastructure such as curb extensions or pedestrian refuge islands. While more permanent infrastructure with concrete is generally considered effective, specific details about temporary infrastructure with flexible delineators (or bollards), such as installation, use and safety impact, would be valuable to optimize cost-effectiveness. This project evaluated both temporary and permanent pedestrian infrastructure at crossing sites to measure the effects on pedestrian safety and driver behavior.

Assessing Recycled Pavement for Use in Road Design

Cold recycling road pavement materials into new road construction is a cost-effective and sustainable practice. However, the properties of these materials must be characterized to adequately design pavement structures. This project developed a framework and tool for transportation agencies to estimate the key material properties of cold recycled materials incorporated into road designs.

Limiting Pavement Damage from Detours

Detours for highway construction projects direct heavy freight vehicles onto local roads that were not designed to accommodate the frequency of heavy loads. Detours to these local roads often accelerate pavement deterioration that shortens their service life and requires additional repair. This project examined the structural and economic impacts of detours on local roads to develop a framework for optimizing detour routes that limit pavement damage while maintaining traffic mobility.

Assessing Rejuvenators That Extend Pavement Service Life

Over time, asphalt pavement becomes stiff and brittle due to oxidation, often leading to surface cracking and distress. To mitigate these damages and extend the service lives of roads, transportation agencies may apply a spray-on rejuvenator (SOR) to restore essential components of the asphalt. This project investigated the short- and long-term effectiveness of 12 SORs that state and local transportation agencies may consider for future use.

Increasing Equity in Transportation Investments

Historically, equity has not been a primary objective in the transportation infrastructure investment planning process. By effectively incorporating equity into the process, underserved communities and Native nations can realize increased benefits from transportation improvements. This research explored effective strategies for incorporating equity in transportation capital investment planning and provides guidance to transportation agencies, planning organizations and Native nations.

Evaluating Taconite as a Lower Cost Friction Treatment

High friction surface treatments (HFSTs) on Minnesota roads are composed of imported, industry standard calcined bauxite aggregate. This material is expensive, and producing it is energy-intensive. Taconite aggregate, a by-product of the Minnesota mining industry, is a potential alternative to calcined bauxite that is less expensive. This research compared taconite and calcined bauxite in field skid resistance performance testing to determine the feasibility of using taconite in place of calcined bauxite in HFST applications.
