In a project funded by the National Cooperative Highway Research Program (NCHRP), Portland State University is partnering with the University of North Carolina at Chapel Hill and Safe Streets to develop guidance to help agencies identify the appropriate crosswalk spacing to ensure that people can cross arterials and other streets at safe crossing locations, and that a...

Evaluation of Bus-Bicycle and Bus/Right-Turn Traffic Delays and Conflicts
Miguel Andres Figliozzi
The interaction between transit vehicles and bicycles can create conflict when both share the same space. In particular, the location of transit stops poses specific challenges along bicycle facilities. Little research exists to offer insight on how the placement of transit stops affect bicycle safety and comfort levels or how bicycle flow affects transit operations (stop dwell times, delays, etc.). This project builds on existing UTC-funded work using high-resolution bus GPS data to analyze ...
