基于相位优化的公交优先单点控制策略研究

建立了公交专用道公交独立相位,从交叉口控制策略的各种协同关系出发,系统分析了动态公交相位的优先级关系,提出了公交相位剩余时间的二次分配问题,建立了公交相位实时在线控制逻辑框架,实现了公交相位与社会相位之间的优化组合,最后运用VISSIM进行了系统仿真和效果评价,结果表明优化策略实现了交叉口公交优先和交通畅通有序的控制效果.

Transit Priority Control Strategy of Single Point Based on the Phase Optimization

In this thesis we set up the bus independent phase at bus line,analyzed the priority relationship of dynamic bus phase systematically and proposed the problem of re-distribution of the remainder of bus phase.Meanwhile,we also established the real-time online bus phase control logic framework,realized the optimization between the bus phase and the social phase and finally used VISSIM for the system simulation and evaluation.The results show that the optimization strategy has achieved the bus priority and smo...
