公交优先仿真系统概念设计

首先综述了公交优先仿真技术的发展状况。然后,基于对实际公交优先管理系统的解析,将公交优先仿真模型划分为交通管理系统背景模型、公交优先设施模型、公交线网模型、公交车特性行为模型、信息采集模型、通信系统模型、公交优先策略模型、公交优先信号模型等。由此进一步给出了仿真系统概念设计方案。该方案将仿真系统分解为路网交通状态模拟、信息采集、通信、公交调度中心、信号控制中心及本地控制机等模块,并定义了各模块的主要功能和相互间的信息交换内容。

A Conceptual Design of Bus Priority Simulation System

The state-of-the-art of bus priority simulation technology is reviewed at first.Then,based on the analysis of real bus priority management system,a classification of bus priority simulation models is put forward,which includes traffic management system background models,bus priority infrastructure models,bus route models,bus-specific driving behaviour models,information collection models,communication models,bus priority strategy models,bus signal priority models.Whereafter,a conceptual design of bus priority system is proposed,in which,the system is broken down into some major modules including network traffic status module,information collection module,communication module,bus dispatch center module,signal control center model and local controller module,the functions of each module and exchange information contents among these modules are also defined.
