快速路出口与衔接道路平交口的协调控制问题研究

当出口匝道接地点离交叉口距离太近时，采用基于优先控制思想的协调控制方法，在避免衔接交叉口的拥堵易回溢至快速路主线等方面有较好的实际应用效果。同时，优先感应采用国际通用的NEMA感应规则，可架起快速路控制与城市道路信号控制的桥梁，使两个原本独立的系统在本地控制层面有效地结合起来。

Research on Integrated Control Model of Expressway Off-ramp and Correlative Intersection

When the exit ramp takes place within a short distance from the intersection, an integrated control model based on priority and preemption control can achieve better practical applications of keepping the queues of intersection and off-ramp from backupping to expressway mainline. At the same time, priority induction puts up a bridge between expressway control and urban road signal control by using international common NEMA sense rules,which can make the two originally separate systems combine effectively in the local control level.
