【摘要】：针对高速公路收费站交通拥堵时车辆长时怠速且频繁启动导致油耗急剧增加的问题,提出了收费站拥堵车流交通控制系统。该系统通过设置车辆感应器防止收费亭空闲,利用车流控制灯将拥挤缓行的车流变为分批放行车流,综合考虑排队长度、收费通道数、收费广场长度、主线车道数、收费时间等因素,以排队系统中车辆油耗最低为目标,建立了车辆感应器和信号灯位置及信号灯时长等参数优化模型,从而实现了不增加车辆通行时间同时减少车辆怠速时间和停车次数的目的。最后结合实例,运用交通模拟技术对该控制系统效果进行了验证。结果表明:当收费站排队长度为2 000m时,采用该控制系统可使车辆通过收费站的油耗降低90%。
[Abstract]:Aiming at the problem of long idle speed and frequent start-up of vehicles in freeway toll stations, fuel consumption increases sharply. A traffic control system for congested traffic in toll stations is proposed. The system uses vehicle sensors to prevent toll booths from idle, and uses traffic flow control lights to turn traffic flow into batch traffic flow, taking into account the queue length. The number of toll lanes, the length of toll plaza, the number of main lanes, the time of charging, and so on, aim at the lowest fuel consumption of vehicles in the queuing system. The optimization model of vehicle sensor and signal lamp position and signal time is established, which realizes the purpose of reducing the idle time and parking times without increasing the traffic time. Finally, an example is given. The effect of the control system is verified by using traffic simulation technology. The results show that when the queue length of toll station is 2 000m, the fuel consumption of vehicle passing through the toll station can be reduced by 90% when the queue length is 2 000m.

【正文快照】： 0引言受恶劣天气、交通事故、交通需求波动等因素的影响,高速公路收费站常常出现排队长龙,尤其是高速公路主线收费站,由于其通行能力远小于路段通行能力,当交通流急增时,很容易形成大面积的交通拥挤。例如2012年国庆期间,惠河高速平南至泰美段,车辆排队长度达40km;2013年春运
