高等级公路收费站通行能力分析

高等级公路收费站的通行能力直接影响着路段通行能力，从而在总体上制约着公路的交通运行状况．因此提高高等级公路收费站的通行能力和服务水平，是改善高等级公路通行能力及服务水平的有效方法．本文根据高等级公路收费站交通流特性的分析，建立了收费站的排队模型．在深入分析实地调查数据的基础上，应用M／G／K模型，计算出了适合在不同服务水平下的收费站最大服务交通量，并提出了分析收费站通行能力的方法．

Traffic Capacity Analysis of High-Level Highway Tollgates

The traffic capacity of tollgates on the high-level highways influences the traffic capacity of highway section directly,thus the traffic conditions is restricted on the whole.So improving the traffic capacity of the tollgates and their service level is an effective method.According to the analysis of the traffic flow characteristics on the highways,a tollgate model of standing in line is set up in this paper,and the maximum service volume of different level of service is presented through analyzing the field data in detail with M/G/K model.The method to analyze traffic capacity of tollgates is put forward.
