To improve the level of service for Community Transit (CT) buses, the South Snohomish Regional Transit Signal Priority (SS-RTSP) project was launched. To understand the overall benefit of this project, the SS-RTSP system was tested and evaluated after the hardware and software had been installed on the 164 th Street SW corridor (Phase One) and the SR 99 corridor (Phase Two) in Snohomish County,...

When multiple bus vehicles send priority requests at a single intersection, the existing fixed-phase sequence control methods cannot provide traffic request services for multiphase vehicles. In view of conflict intersections, vehicle is determined, which focus this study. paper, connected vehicle-enabled transit signal system (CV-TSPS) has been proposed, uses vehicle-infrastructure communicatio...

In this paper, data from an on-site survey in Seoul, Korea and the microscopic traffic simulation are used to evaluate the performances of Bus Rapid Transit bus stops operated on different placements to their nearest traffic signals: far-side, and near-side. The influence of Bus Priority Signal Systems is also analyzed. The results reveal that a near-side bus stop performs better under the curr...

Real-time network signal control offer the potential to provide delay benefits over traditional fixed time and actuated control. The SPPORT (Signal Priority Procedure for Optimization in Real-Time) model is a fully distributed heuristic rule-based signal control method that explicitly considers transit priority. While a distributed architecture enables the network control problem to be decompos...

In this study, a comprehensive set of transit, intermodal and multimodal assignment models (FAST-TrIPs) is developed for transportation planning and operations purposes. The core part of the models is a schedule-based transit assignment with capacity constraint and boarding priority. The problem is defined to model the system performance dynamically by taking into account the scheduled transit ...
