Evaluation of Bus-Bicycle and Bus/Right-Turn Traffic Delays and Conflicts

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 ...

The state of Oregon has one of the highest per-capita EV sales markets in the country. However, much is to be done if Oregon is to reach their ambitious goal of complete electrification of the private automobile ind...
