基于车路协同的特种车辆绿波通行

基于车路协同技术，提出了通过定位与检测特种车辆通行状态，控制信号灯提前或延长特种车辆所在方向绿灯相位以及车速引导来实现特种车辆绿波通行的方案。运用VISSIM仿真模拟金山大道通行情况，在本文方案下特种车辆通行时间减少了81%，验证该方案可提升通行效率。

Green wave traffic of special vehicles based on vehicle-road coordination

Based on the vehicle-road coordination technology, a scheme was proposed to realize the green wave passing of special vehicles by locating and detecting the traffic status of special vehicles, and controlling the signal lights to advance or extend the phase of the green light in the direction of the special vehicles and provide speed guidance. VISSIM was used to simulate the traffic situation of Jinshan Road, and results show that the traffic time of special vehicles is reduced by 81% under the proposed scheme, which verify that the scheme can improve the traffic efficiency.
