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… Read More

Pedestrian and Bicycle Master Planning: Training for Practitioners

Lynn Weigand
The growing focus on context sensitive solutions and design in roadway planning, increased support for addressing public health objectives through transportation and land use planning, and concerns about oil dependence and global warming all point to a need for planning practitioners to have more knowledge and skills related to pedestrian and bicycle planning. At the same time, the amount of funding going toward pedestrian and bicycle infrastructure has increased significantly since the early… Read More
