针对高速公路施工段、收费站等通行能力瓶颈路段等时常出现的车辆拥挤缓行、频繁停行、燃油急剧增加的问题,在充分调查交通拥挤缓行时车流特征的基础上,结合交通控制、感应检测等技术,建立了基于节能减排的交通拥挤缓行车流控制系统。实例分析表明:该控制系统在不增加车辆通过时间的前提下,大幅减少了车辆的起停次数,降低了燃油消耗。 In view of the problems such as congestion, frequent stop and sharp increase of fuel consumption, such as traffic congestion bottleneck sections such as expressway construction section and tollbooth toll stations, traffic congestion control, sensor detection And other technologies, based on energy saving emission reduction traffic congestion control flow control system. The case study shows that the control system can significantly reduce the starting and stopping times of vehicles and reduce the fuel consumption without increasing the passing time of vehicles.
