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-...

Community-based Assessment of Transportation Needs to inform City of Portland Smart Cities Plan
Aaron Golub
The Portland Smart Cities UB Mobile PDX proposal is being transformed into a City of Portland Smart cities plan. The original proposal focused strongly on developing mobility solutions that would serve traditionally underserved populations. As the proposal moves into a plan, we intend to deepen our community engagement work, explore and assess what the transportation needs are in traditionally underserved communities, and explore how new mobility solutions embedded in Mobile PDX can best be c...
