Data-Driven Mobility Strategies for Multimodal Transportation
Yao-Jan Wu
Xianfeng (Terry) Yang , Sirisha Kothuri
How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit?
The project was led by Yao Jan Wu, director of the Smart Transportation Lab at the University of Arizona. Co-investigators were Xianfeng Terry Yang of the University of Utah, who researches traffic operations and modeling along with connected automated vehicles, and Sirisha Kothuri of Portland State University, ...

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 ...
