摘要:针对高峰时段高速公路收费广场交通拥堵现象日益严重,介绍了收费站的收费通行方式,搭建车辆分段经过收费广场的时间延误模型、车辆换道模型和综合评价模型,考虑到收费站的建设成本,利用模糊层次分析法分析评价了传统单亭式收费广场的车辆交通流。为提高收费站的交通流量、安全性和经济性,提出了改进型单入双出复式双亭收费车道,通过理论设计、数值分析、模拟仿真,以及对低车流量和堵车情况时的性能分析,较好的验证了该设计方案的可行性,为我国高速路收费广场建设提供了一条新思路。
Abstract: In response to the increasingly serious traffic congestion on the toll plaza during the peak hours, the toll collection station's charging method was introduced, the time delay model for building vehicles passing through the toll plaza, the vehicle lane change model, and the comprehensive evaluation model were taken into consideration, taking into account the construction cost of the toll station. Using fuzzy analytic hierarchy process to analyze and evaluate the vehicle traffic flow in the traditional single booth toll plaza. In order to improve the traffic flow, safety and economy of the toll station, an improved single-in, double-out, dual-kiosk toll lane was proposed, through theoretical design, numerical analysis, simulation, and analysis of performance at low traffic flow and traffic jams. This has proved the feasibility of the design proposal and provided a new idea for the construction of the toll plaza in China.

随着我国经济水平飞速发展,汽车保有量持续增加,人口流动和物质交换需求日益变大,高速公路的交通量呈现逐年增长趋势[1,2]。收费站作为高速公路通信能力的瓶颈,尤其是在节假日及早晚高峰时段,交通拥堵现象十分严重。因此,分析高速公路主线收费站拥堵机理和事故应急处理,规划设计一种新型收费车道,确保高峰时段收费广场车流量畅通,是高速公路收费站设计管理中所面临的重要任务[3],对加快我国高速路经济发展建设、提高人民生活质量有着积极影响。
1 收费站收费方式
高速公路收费站往往通过“坡道收费”和“障碍收费”收取过往车辆的通行费用。坡道收费是设立在高速公路的出入口斜坡处的收费窗口。……
