Title: Comprehensive Evaluation of a Transit Signal Priority System Using Observed and Simulated Traffic Data
Accession Number: 01088562
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: The South Snohomish Regional Transit Signal Priority (SS-RTSP) project was launched to improve the level of service for Community Transit buses. To understand the overall benefit of this project, the SS-RTSP system was tested and evaluated after the completion of the hardware and software installations on the 164th Street SW street corridor (phase-one) and the SR-99 corridor (phase-two) in Snohomish County, Washington. In this study, impacts of the SS-RTSP system on both transit and local traffic operations were quantitatively evaluated based on field data. Simulation models were also built and calibrated to compute measures of effectiveness that could not be obtained from field data. The evaluation showed that the SS-RTSP system produced remarkable benefits to transit vehicles with insignificant negative impacts to local traffic on cross streets. The overall impact of the SS-RTSP system on local traffic at each intersection was not statistically significant at the p=0.05 level. Recommendations are also given to improve the performance of the current TSP system.
