Research Highlights
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 ...

Improving Trip Generation Methods for Livable Communities
Kelly Clifton
Nico Larco
This NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers. Headed by Kelly Clifton of Portland State University and Nico Larco of the University of Oregon, this project is the latest effort in an ongoing collaboration to create more open sourced, widely available data about non-motorized road users.
Over the last decades, cities have become more invested in fostering the ...
