摘要
交通道路情况复杂多样,干线协调控制优化方法可根据实际道路问题进行改进。本研究为了优化高峰时段的连续T型交叉口交通状况,基于传统AM-BAND模型,结合双周期协调控制理论改进模型。并以南昌市红谷滩区赣江中大道为例,利用模型对协调控制方案进行优化,并对改进前后的协调控制方案进行仿真验证,通过对比评价指标数据,干线总延误减少16.78%,平均延误减少21.48%,总停车次数减少27.93%,平均停车次数减少31.78%,改进后的双周期协调控制模型有效优化了连续T型交叉口的交通状况,使得高峰时段内,道路拥堵情况大大减少,车辆通行更加顺畅。
Traffic road conditions are complex and diverse,and the optimization method of trunk coordination control can be improved according to the actual road problems.In order to optimize the traffic conditions of continuous T-intersections during peak hours,this study improved the model based on the traditional AM-BAND model and combined with the two-cycle coordinated control theory.Taking Ganjiangzhong Avenue,Honggutan District,Nanchang City as an example,the coordinated control scheme was optimized by using the model,and the coordinated control scheme before and after the improvement was verified by simulation.By comparing the evaluation index data,the total delay of the trunk line was reduced by 16.78%,the average delay was reduced by 21.48%,the total number of stops was reduced by 27.93%,and the average number of stops was reduced by 31.78%.The improved two-cycle coordinated control model effectively optimizes the traffic conditions of continuous T-intersections,which greatly reduces the road congestion during peak hours and enables vehicles to pass more smoothly.
