摘　　要：实时车速是城市智能化的核心基础数据。基于ITS子系统,包括先进的交通管理系统(ATMS)、自动车辆识别(AVI)系统、车载GPS系统和视频采集系统,分析其实时车速信息采集与整合的几种方法;对比分析两种数据采集结构,即完全分布式和分布式;详细讨论数据描述、数据存储以及数据传输问题;提出区域范围内实时车速的采集系统应该与现有ITS子系统相结合,有效利用实时数据资源,对ITS数据采集、处理和分析具有重要的理论意义和应用价值。Real?time speed is the key data bases of urban intelligentized transportationBased on ITS subsystems,including the ATMS,AVI,GPS and vision?based collection system,several methods of real?time speed collection are discussed in detail,especially on data description,data storage and data transmissionTwo system architectures are contrasted and analyzed,vizcompletely distributed architecture and distributed system with centralized repositoryHence development of an area?wide real?time speed collection system integrating subsystems of ITS is put forward,and real?time traffic data resource can be made full use of,which is important both in theory and in practical application for ITS data collection,processing and analysis
