The invention discloses an emergency vehicle tailgating passage and special signal control method, which comprises the following steps of: acquiring physical characteristics of an intersection, social vehicle states and flow, quantity and density of vehicles under different flow rates, and calculating the length of a reverse left-turn lane of the intersection according to a shock wave theory; if the emergency vehicle arrives at the intersection, taking a reverse left-turn lane as an emergency lane, carrying out pre-signal control to empty social vehicles on the emergency lane, and carrying out speed guidance on the emergency vehicle in a speed guidance area; and calculating the green light turn-on time and duration of the emergency phase of the emergency vehicle, and calculating the intersection signal timing by taking the emergency vehicle passing through the intersection preferentially and the conflict relation of different phases of the intersection as constraints and taking the minimum total travel time of social vehicles as a target. According to the invention, under the existing urban traffic condition, the emergency vehicle speed and intersection signal control scheme is collaboratively optimized, and the social vehicle benefits are ensured under the condition that the emergency vehicles pass preferentially.

    本发明公开了一种应急车辆借道通行及专用信号控制方法,包括:采集交叉口物理特征、社会车辆状态和不同流率下车辆的流量、数量和密度,根据冲击波理论计算计算交叉口的逆向左转车道长度;若应急车辆到达交叉口,将逆向左转车道作为应急车道,进行预信号控制来清空应急车道的社会车辆,并在速度引导区域对应急车辆进行速度引导;计算应急车辆的应急相位的绿灯开启时间与持续时间,以应急车辆优先通过交叉口和交叉口不同相位冲突关系为约束,以社会车辆总出行时间最小为目标,计算交叉口信号配时。本发明在现有城市交通的条件下,对应急车辆速度和交叉口信号控制方案协同优化,在应急车辆优先通行下保证社会车辆效益。
