本申请涉及智慧交通技术领域,公开了一种区域交叉口的车辆通行方法和边缘计算设备。获取第一检测区域的描述信息;若确定第一检测区域处于拥堵状态,则控制下匝道信号机执行自适应交替放行策略;自适应交替放行策略为根据第二检测区域的车辆排队情况和第三检测区域的车道车流密度确定的主路和辅路交替放行的策略;若检测到下匝道信号机执行自适应交替放行策略的时长大于第一设定时长,第一检测区域仍处于拥堵状态,且第四检测区域处于拥堵状态,则控制上游信号机、下游信号机和匝道信号机执行多路口联动控制策略:上游信号机压缩绿灯时长的策略、下游信号机执行延长绿灯时长的策略,以及下匝道信号机的控制策略。提高下匝道路口的车辆通行效率。
The invention relates to the technical field of intelligent traffic, and discloses a vehicle passing method at a regional intersection and edge computing equipment. Acquiring description information of the first detection area; if it is determined that the first detection area is in the congestion state, an off-ramp signal machine is controlled to execute a self-adaptive alternate release strategy; the self-adaptive alternate release strategy is a main road and side road alternate release strategy determined according to the vehicle queuing condition of the second detection area and the lane traffic flow density of the third detection area; if it is detected that the duration for the off-ramp signal machine to execute the self-adaptive alternate release strategy is longer than a first set duration, the first detection area is still in a congestion state, and the fourth detection area is in a congestion state; if yes, the upstream signal machine, the downstream signal machine and the ramp signal machine are controlled to execute a multi-intersection linkage control strategy including the strategy that the upstream signal machine compresses the green light duration, the strategy that the downstream signal machine prolongs the green light duration, and the control strategy that the down-ramp signal machine is used for controlling the down-ramp signal machine to execute the multi-intersection linkage control strategy. And the vehicle passing efficiency of the off-ramp intersection is improved.
