Research Highlights
Pedestrian and Bicycle Master Planning: Training for Practitioners
Lynn Weigand
The growing focus on context sensitive solutions and design in roadway planning, increased support for addressing public health objectives through transportation and land use planning, and concerns about oil dependence and global warming all point to a need for planning practitioners to have more knowledge and skills related to pedestrian and bicycle planning. At the same time, the amount of funding going toward pedestrian and bicycle infrastructure has increased significantly since the earl...

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-...
