摘要为有效利用车道资源，提高ETC车辆的通过率，部分省份将军警车道升级改造成前置式军警ETC车道或后置式军警ETC车道，但不同军警ETC车道布局对收费站服务水平的影响程度尚不明确。文中以广韶高速太和收费站为研究对象，运用Vissim交通仿真软件进行仿真建模，对比分析不同军警ETC车道布局下ETC车辆、军警车辆、人工半自动收费(MTC)车辆等车种的平均行程时间、平均延误时间、平均排队长度等评价指标。仿真结果表明：经升级改造后，ETC车辆的各项评价指标改善显著，军警车辆受到较小的影响，MTC车辆未受到影响；在低峰、平峰时段中，2种军警ETC车道布局模式下收费站的各项评价指标差别较小，在高峰时段中，与前置式布局模式相比，后置式布局模式下ETC车辆和军警车辆的平均行程时间均提高了9.6%、平均延误时间均降低了12.8%、平均排队长度均减少了26.7%。因此，建议交通流量较大的大型收费站采用后置式军警ETC车道布局模式，交通流量较小的小型收费站可采用前置式或后置式军警ETC车道布局模式。

Abstract:In order to use resources of lanes effectively and improve the passing rate of ETC (Electronic Toll Collection) vehicles, some provinces upgraded the lane for police cars of toll stations to a front mounted or a rear mounted layout of lane for both police vehicles and ETC vehicles, but the influence of the different layouts of lane for both police cars and ETC vehicles on service level of toll station was unclear. In view of this, this paper took the Taihe toll station of Guangshao freeway as a case study, and used the Vissim traffic simulation software to build up several simulation models, and analysis the average travel time, the average delay, the average queue length of ETC vehicles, police vehicles and MTC (Manual Toll Collection) vehicles by the different layouts of lane for both police vehicles and ETC vehicles. The simulation result showed that the evaluation indexes of ETC vehicles improved significantly after upgrading, the evaluation indexes of police vehicles had a small influence, and the evaluation indexes of MTC vehicle were not affected. In the low peak and flat peak time, the evaluation indexes of both front and rear mounted layouts of lanes are nearly the same. In the peak time, compared to the front mounted layout of lane, the average travel time of ETC vehicle and police vehicles increased 9.6%, the average delay time decreased 12.8%, the average queue length were reduced 26.7% in the rear mounted layout of lane. Therefore, this paper suggests that larger stations which have large flows are more suitable to use the rear mounted layout of lane, and smaller stations which have small flows can use a front mounted layout of lane or a rear mounted layout of lane.
