| 摘 要： | 提出了一种在干线协调控制背景下的主动式公交信号优先方法,旨在达到公交车辆、社会车辆共同利益最大化的目标。首先需要明确干线协调与公交优先的优先级关系,确立双层优化方法,上层为干线协调,下层为公交优先。优先方法中采用主动式早启、晚断模式为核心模块,绿波带上下限作为约束条件调整公交信号优先的具体方案。然后,根据优化方法,构建了由公交请求生成系统、通信系统、交通信号控制系统组成的主动式公交信号优先系统。最后通过系统验证分析,从干线协调效果和公交车辆延误时间等方面评价了这种优先方法的具体效果,并给出了实际应用建议。

| Abstract: | A method of active public traffic signal priority based on coordination of trunk road for maximizing the common interest of buses and cars is described.First,it is necessary to make sure the relative priorities of trunk road coordination and public traffic priority and determine double layer optimization.The upper of double layer optimization is for coordination of trunk road,and the lower is for public traffic priority.The core module consists of active advanced and extended control in the priority method ... |
