城市快速路出入口匝道联动控制策略研究

Coordination Control Strategy of Urban Expressway On-ramp and Off-ramp

以北京市快速路为研究对象,对分布密集的出入口匝道实施信号联动控制。为减少驶入与驶出车流间的交织冲突,保证快速路主线交通流处于最佳运行状态,提出出入口匝道信号联动控制方法。采用Vissim对提出的控制方法进行模拟验证,结果表明该方法可以提高主线车辆的运行速度,有效缓解交织区的严重冲突现象。

By taking Beijing urban expressway as research object, the coordination control strategy between the close on-ramp and off-ramp was studied. In order to reduce the conflicts between the traffic streams of entering and exiting and to ensure the optimal traffic state of the mainline, the on-ramp and off-ramp signal coordination control method was proposed. The method was simulated by VISSIM. The result shows that it can improve the vehicles average speed of the mainline and effectively reduce the conflicts at weaving area.
