摘要：	Transit signal priority (TSP) is an operational strategy that facilitates the movement of in-service transit vehicles through signalized intersections. To improve the level of Community Transit (CT) services, the South Snohomish Regional Transit Signal Priority (SS-RTSP) project has been launched. To understand the overall benefit of this project, the SS-RTSP system (phase one) was tested and evaluated after the completion of the hardware and software installations on the 164th Street SW street corridor in Snohomish County. In this study, impacts of the SS-RTSP system on both transit and local traffic operations were quantitatively evaluated based on field observed data. A simulation model was also built and calibrated to compute measures of effectiveness that cannot be obtained from field-observed data. With the simulation model and field observed data, the impacts of the SS-RTSP system on both transit and local traffic operations were quantitatively evaluated. Our evaluation results showed that the SS-RTSP system introduced noticeable 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 of the whole intersection was net benefit.
