深圳“城市交通仿真与公用信息平台”设计与实践

Design and Development of Shenzhen Urban Traffic Simulation and Public Transport Information Platform

深圳市城市交通仿真系统(SUTSS)是深圳“城市交通仿真与公用信息平台”的一期建设内容和启动工程,以城市智能交通公用信息平台为依托,以城市交通仿真为核心技术是本期建设的技术思想。系统包括:城市交通信息通信与传输网络;城市交通信息综合采集与处理系统;城市交通仿真(宏观、中观、微观)系统;城市智能交通公用信息平台和城市交通信息服务系统五个部分。如何从构架城市智能交通公用信息平台体系结构入手,将城市交通信息采集、城市交通信息通信与传输、城市交通仿真、城市交通信息服务等作为城市智能交通公用信息平台一体化设计与建设,是这一大型系统工程的关键之处。

Shenzhen urban traffic simulation system （SUTSS） is the first phase for the development of an intelligent transport information platform for planning and public information service purposes, and its main theme is to construct a core traffic simulation system based upon the urban intelligent transport information platform for Shenzhen. The project consists of five components： a network and communication system for transport information, a subsystem for data collection of transport information, a traffic simulation subsystem （ including macro, meso and micro levels） and a service subsystem to provide supporting traffic information for planning and policy-making purposes. As a huge system, the major challenge is to develop a transport information platform to meet the framework of integrating the four subsystems mentioned above.
