The invention discloses a special lane dynamic control method for a mixed traffic flow of an expressway, and the method comprises the steps: collecting the total number of vehicles in the mixed traffic flow in a current time period and the proportion of connected automatic driving vehicles (CAV); according to the front vehicle type of the vehicle in the mixed traffic flow, calculating the vehicle head distance distribution probability in each following mode and the probability that the vehicle adopts different following modes; calculating the maximum traffic capacity of the one-way single lane of the mixed traffic flow before the CAV special lane is arranged; whether the traffic flow rate of the mixed traffic flow single lane exceeds the maximum traffic capacity or not is judged, namely whether a CAV special lane needs to be arranged or not is judged, and the maximum traffic capacity after the CAV special lane is arranged is calculated; and according to the traffic flow rate, calculating the optimal set number of the CAV special lanes and the corresponding CAV permeability of each lane, and realizing dynamic distribution of traffic flow of each lane.
本发明公开了一种面向高速公路混合交通流的专用道动态控制方法,其步骤包括:采集当前时段内混合交通流的车辆总数和网联自动驾驶车辆(Connected and Automated Vehicles,CAV)的所占比例;根据混合交通流中车辆的前车类型,计算各跟驰模式下的车头间距分布概率和车辆采用不同跟驰模式的概率;计算混合交通流在设置CAV专用道前的单向单车道的最大通行能力;判断混合交通流单车道通行流率是否超过最大通行能力,即是否需要设置CAV专用道,并计算设置CAV专用道后的最大通行能力;根据通行流率计算CAV专用道最优设置数量以及各车道相应的CAV渗透率,实现各车道交通流量动态分配。
