高速公路主线收费站通行能力改善研究

Study on Improvement of Passthrough Capacity of Mainline Toll-stations on Expressways

高速公路主线收费站的通行能力直接影响着整个路段的通行能力,针对高速公路主线收费站运行中出现的"前紧后松"问题,依据主线收费站的建设特点,提出了一种优化改造措施,在分析了收费站车辆到达时间与服务时间分布特点的基础上,借助M/G/K排队模型进行通行能力计算和服务水平评估,并通过实例验证了这种改造措施能够有效地提高通行能力。

In light of the problems in the operation of the mainline toll-stations on expressways and in accordance with the characteristic of their construction, we proposed the measures for their optimization and transformation and, on the basis of an analysis of the distributional characteristic of the arrival time and service time of the vehicles at the toll-stations, used the M/G/K queuing model to calculate the passthrough capacity and to evaluate the service level. At the end, through an empirical case, we demonstrated the measures proposed could effectively improve the passthrough capacity of the stations.
