Research Highlights
Planning Ahead for Livable Communities Along the Powell-Division BRT: Neighborhood Conditions and Change
Lisa Bates
Aaron Golub
New transit investments can be a double-edged sword for disadvantaged communities (e.g. those included in environmental justice and Title VI potected classes). Transit investments improve community’s mobility and access and may improve health with reduced driving nearby. However, there is also the potential for transit-oriented development to spur gentrification and displacement if affordable housing is lost.
Understanding transit corridor conditions and change with new infrastructure is ...

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 ...
