Advancing Safety At Intersections: Measuring The Effectiveness Of Traffic Signal Strategies For Speed Management On Operations And Safety
Sirisha Kothuri
Many states are adopting the Safe System approach (USDOT, 2022) to improve traffic safety. As the role of speed in injury severity is becoming increasingly clear, one of the key elements of a Safe System approach is Safer Speeds. Specifically, higher motor vehicle speeds lead to higher injury severity during a collision, especially for nonmotorized users (Rosén and Sander 2009; Tefft 2013) who are the most vulnerable users in the transportation system. Most pedestrian crashes occur on higher-...

How can community members become more engaged in transportation decision making?
Individuals and groups can learn to effect powerful change, but success requires some familiarity with how civic processes work. Community Transportation Academies, or CTAs, provide a basic technical understanding of how a city or region’s transportation system operates, along with the decision makers and decision-making processes that determine how the system is shaped.
Supported by the National Institute ...
