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-...

Encouraging Low-Income Households to Make Location-Efficient Housing Choices
Andree Tremoulet
The purpose of this project is to develop and evaluate tools to assist Housing Choice Voucher (HCV) program participants in the Portland, OR, metro region with considering transportation needs and options when making decisions about where to live. The project consists of two elements: development of a set of tools in collaboration with the four metro-area housing authorities, and an evaluation of the effectiveness of the tools. The four housing authorities conceptualized and initiated this pr...
