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…

Developing a model for Transit Oriented Development in Latino Immigrant Communities: A National Study of Equity and TOD
Gerardo Sandoval
Multimodal transportation and land use decisions have important effects on vulnerable low-income communities. TOD (transit oriented development) projects can encourage livability and help these communities by providing access to public transportation, affordable housing and jobs via the transportation network (Crane and Schweitzer 2003; Cervero, R.; Ferrell, C; Murphy, S, 2002). NITC is currently funding a comparative case study of TOD projects in Latino immigrant communities in Los Angeles, CA…
