本研究探讨了一些交通参数对公交信号优先（TSP）应用程序的有效性的影响。以温哥华市格兰维尔街沿着98辆B线快速公交车为例，对TSP进行了测试。利用微观模拟软件VISSIM对TSP在廊道上的运行进行了模拟。研究的交通参数包括：公交引道交通量、过街交通量/通行能力（v/c）比、公交车时距、公交车站位置、公交车检票检测器位置、左转条件和信号协调。根据这些实验的结果，建议TSP的应用加连威老街。在一般情况下，它被发现，TSP的应用程序将是最有效的交通条件下，有中度到重度的巴士接近量，很少或没有转向量阻碍巴士运动，轻微到中度的跨街v/c比，farside巴士站，和信号协调的交通运行在高峰方向。
This research examines the impacts of a number of traffic parameters on the effectiveness of a Transit Signal Priority (TSP) application. TSP is tested with the 98 B-line rapid buses along Granville Street in the City of Vancouver as a case study. VISSIM, a micro-simulation software, is used to simulate TSP operation on the corridor. The traffic parameters studied include: bus approach volume, cross street volume/capacity (v/c) ratio, bus headway, bus stop location, bus check-in detector location, left turn condition, and signal coordination. Based on results from these experiments, recommendations are provided for TSP application on Granville Street. In general, it is found that a TSP application would be most effective under a traffic condition that has moderate to heavy bus approach volume, little or no turning volume hindering bus movement, slight to moderate cross street v/c ratio, farside bus stop, and signal coordination for traffic running in peak direction.
