Abstract
Passive transit signal priority (TSP) controls have long been recognized as a viable method for reducing bus delays on urban arterial roads. This paper introduces a partition-enabled multi-path model designed to address the problems of categorizing progression and coordinating signals for multiple bus paths on urban arterials. By incorporating the spatial distribution of bus stations, the proposed approach allows for the subdivision of progressions into multiple sub-progressions, thereby expanding the feasible region. Additionally, this approach considers the potential overlaps or conflicts between different bus paths. The diverse stopping demands of multiple bus paths are also taken into consideration. Furthermore, to get a more feasible solution, we optimize offset and phase sequences at each intersection simultaneously. A binary mixed-integer linear program (BMILP) is used to formulate the proposed models, which can be solved precisely through mathematical solvers or the standard branch-and-bound technique. The numerical examples and simulation experiment results presented in this paper demonstrate that compared with the BUSBAND and INTEBAND, the proposed models can significantly reduce average delays, average stop times, and average travel time for buses while having almost no impact on passenger cars. Furthermore, Model-2, which includes phase sequence optimization, shows higher levels of reliability and effectiveness.
