基于“快出慢进”的城区出入干道的信号协调控制

Exit and entrance trunk road signal coordinated control of urban region based on fast exit and slow entrance

通过采取"快出慢进"交通协调控制优化策略,主线车流早、晚高峰时段的总停车次数比现有的单点信号控制方案分别下降了40%和47%;主线车流由西往东方向的早、晚高峰时段的平均行程车速比现有的单点信号控制方案分别提高了52%和76%,由东往西方向的早、晚高峰时段的平均行程车速比现有的单点信号控制方案分别提高了105%和163%.表明"快出慢进"的交通管理策略能满足交通管理需求,提高主线车流的运行效率.

Compared with the situation single point signal control scheme,the mainline traffic flow total number of section stops in morning and evening peak-hour reduced by 40% and 47% respectively; the mainline traffic flow average travel speed in morning and evening peak-hour from west to east increased by 52% and 76% respectively,the mainline traffic flow average travel speed in morning and evening peak-hour from east to west increased by 105% and 163% respectively,by use of the traffic coordinated control optimization strategy such as＂fast exit and slow entrance＂. It suggested that the traffic management strategy could meet the demand of traffic management,and improve the operation efficiency of mainline traffic flow.
