Webinar: Transit Signal Priority Evaluation and Performance Measures
TREC Webinar Series
  • Miguel Figliozzi, Portland State University
Transit signal priority (TSP) can reduce transit delay at signalized intersections by making phasing adjustments. TSP is a relatively inexpensive tool to provide faster and more reliable transit service. This webinar addresses TSP real-word performance measures as well as data integration and evaluation challenges. Results of the TSP evaluation in an arterial corridor in Portland, Oregon indicate that a timely and effective TSP system requires a high degree of sophistication, monitoring, and maintenance. TSP timing is crucial to reduce transit delay. Key takeaways include: performance measures, methodology, analysis of early green and red extension pros and cons, novel real-world results.

Miguel Figliozzi is a professor in the Civil and Environmental Department at Portland State University and director of the Transportation Technology and People (TTP) lab. Figliozzi has been collaborating with TriMet, the Portland region's transit agency, for several years. Recent transit research has dealt with the evaluation of TSP systems, travel time reliability, bus stop consolidation, transit performance measures and transit data visualization.
