可变信息标志(variable message signs,VMS)作为交通诱导信息的主要发布方式,对城市交通管理起到重要作用。为了提供更合理有效的策略支持系统,在分析VMS发布信息数据资源的基础上,提出了基于历史经验数据的诱导策略发布流程与支持算法,通过将空间地理信息、既有诱导信息和交通流等数据相结合的信息处理技术,建立了VMS诱导信息数据资源管理与发布支持平台,可进行VMS信息、交通流数据和道路交通流相关性的统计分析,实现了包括VMS信息发布内容、时间和范围的策略生成功能。研究结果可作为城市交通信息服务和管理系统的基础组成部分,为城市交通诱导信息发布提供更为合理的策略支持。
Variable message signs (VMS), as the main way to guide the traffic information, play an important role in urban traffic management. In order to provide a more reasonable and effective strategy support system, based on the analysis of the information resources of VMS, an induction strategy publishing process and supporting algorithm based on historical experience data are proposed. Through the introduction of spatial geographic information, induced information and traffic flow Data and information processing technology, a VMS-induced information data resource management and release support platform has been set up, and the statistical analysis of the correlation between VMS information, traffic flow data and road traffic flow can be made. The content, time and scope of VMS information release Strategy generation function. The results can be used as the basic part of urban traffic information service and management system to provide more reasonable tactical support for urban traffic-induced information release.
