摘要
介绍了收费站仿真模型的主要模块,讨论了仿真程序的总体框架及数据结构,介绍了关键类的主要成员变量和成员函数,在此基础上开发了ETC收费站仿真程序。选择沪宁高速公路无锡东收费站作为仿真对象,对其交通流特性做了调查和分析。利用仿真程序ETSP对1条、2条和3条ETC专用车道情况下的收费站平均延误进行仿真,绘制出低、中、高三个代表性交通量下的ETC车道数对收费站整体服务水平的影响图,分析了ETC车道数和收费站通行能力之间的关系,以确定最适当的ETC车道配置数量,为ETC的实施提供依据。
The software framework and data structure of simulation model for ETC toll station were introduced firstly.On the base of the major variable and member function, Electronic Toll Simulation Program （ETSP） was developed.The traffic flow characters for simulation of East Wuxi toll station in Shanghai-Nanjing expressway were investigated and analyzed. The ETSP was running respectively under the situation of one/two/three ETC lane （s）, and the curve diagrams were outputted corresponding to the low/middle/high traffic flow. The relationship between numbers of ETC lane and service level was analyzed accordingly, which to be the basis to determine the most appropriate number of ETC lane in a certain condition.
