Transportation Undergraduate Research Fellowship (TURF)
Avinash Unnikrishnan
Miguel Andres Figliozzi , Christopher Monsere
The main purpose of the Transportation Undergraduate Research Fellowship (TURF) Program is to expose and equip engineering undergraduate students with critical thinking and research skills and tools through supervised research on topics relevant to transportation engineering and planning with a livability theme under a faculty mentor. The program enables undergraduate students to work with a faculty on a pre-approved research plan. At the end of the research program, the students will be expe...

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-...
