Research Highlights

Transit Impacts on Jobs, People and Real Estate

Arthur C. Nelson Kristina Currans , Nicole Iroz-Elardo
Transit Impacts on Jobs, People and Real Estate, from the University of Arizona, represents the culmination of nearly a decade of research into the economic effects of transit. To unpack the dense and substantial findings from 17 LRT, 14 BRT, 9 SCT, and 12 CRT systems in 35 metro areas across the United States, the final report is split into five volumes. Arthur C. Nelson and fellow researchers Robert Hibberd, Kristina Currans and Nicole Iroz-Elardo of UA have completed the final phase of… Read More

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… Read More
