摘要
在实际绿波控制应用中,公交车进站停靠所形成的交通瓶颈往往会使路段实际通行能力降低,对绿波控制效果产生一定的影响.应用集散波理论分析了公交车进站停靠对最大绿波带宽的影响,并提出了在无公交车停靠和有公交车停靠两种情况下,不同的绿波控制相位差及最大绿波带宽的计算方法,在VISSIM仿真平台进行了在线仿真,仿真结果表明:考虑公交瓶颈影响下获得的绿波带参数,其控制效果明显优于未考虑公交瓶颈影响下的控制效果,同时也验证了应用集散波理论获取公交停靠瓶颈下绿波控制参数方法的可行性.
In the real Green Wave Control applications, the traffic bottlenecks caused by the bus stop always reduce road traffic capacity, which make some influence on the Green Wave Control. Firstly, gather-disperse wave theory is used to analyze the effect that the bus stop make to the maximum green wave band. Then the calculation methods of phase difference and the maximum green wave are put forward at the bus stops or no bus stops case. Finally, the simulation is made on the software VIS- SIM. The simulation result, on one hand, shows that the parameter control of the phase difference is better when considering the influence of the bus stop than not considering, on the other hand, verifies the feasibility that using the Gather-disperse wave to obtain the control parameters under the bottle- neck of bus stop.
