摘　　要：针对目前基于GPS浮动车的交通信息采集方法相关研究不够系统、全面,导致大量基础数据浪费、交通信息质量偏低、系统运行成本较高等问题,提出了一种新的基于GPS浮动车的交通信息采集方法。依托长春市局部路网的空间信息,采集GPS实测数据进行技术验证。验证结果表明:本文方法可以很好地解决已有方法存在的诸多问题,从而为改善交通状态判别及车辆动态导航系统的应用效果奠定数据基础。According to the problem of lack of systematic and overall studies on traffic information collection methods based on GPS equipped floating car at present,which leads to a large number of basic data wasted, the low quality output traffic data,the high cost of system etc,the key technologies of traffic information collection based on GPS equipped floating car are put forward,and the functions of the key technologies are indicated,and the key technologies are studied deeply. The key technologies are verified with measured GPS data which collected on the part road network of Changchun,China. The results show that the key technologies and algorithms put forward above have obvious effects for solving problems,which will improve application effects of the road traffic conditions identification and vehicle dynamic navigation systems.
