城市道路交通安全管理决策支持系统

Decision support system of traffic safety management

针对城市道路交通安全管理的流程、模式及特点,结合决策支持系统的理论和方法,采用决策支持四库模式,对道路交通安全信息进行采集、管理、分析、决策和反馈。按照管理决策支持系统建立的一般过程,对系统的功能和构成进行研究,确定系统组成和构建方法。该系统包括7个子系统,分别是道路交通安全综合信息管理子系统、事故成因分析子系统、事故预测子系统、道路交通事件管理及预警子系统、安全评价子系统、安全对策子系统和经济分析及决策子系统。并对数据的管理和实现、模型的实现以及人机界面等方面进行设计,结合程序开发流程,进行了实例应用研究。

Aiming at the process, mode and characters of urban road traffic safety management, four databases model of DSS integrating decision support system theory and technology was adopted to collect, analyze, manage, decide and feed back road traffic safety information. The system function and structure were studied according to the general building process of management on DSS, the main parts and constructional methods were decided. The system was designed from seven parts： integrated road traffic safety information management subsystem, accident causation analysis subsystem, traffic accident prediction subsystem, traffic incident management and alarming in advance subsystem, safety evaluation subsystem, safety countermeasures subsystem, economicanalysis and decision subsystem. The data management and realization, modal realization and man-machine interface were designed, an application example was studied with integrating program development flow. 6 figs, 11 refs.
