Abstract

Abstract: Traffic data collecting and processing are the basis of intelligent transportation technology. Through analyzing types of traffic data collecting techniques，a new measure based on CDMA is presented. The Structure of traffic data collection system is also given. The procedure of data processing combined with the characteristics of the traffic in urban road is described. The traffic road condition is displayed real-time on GIS map. Finally，a case study in the city of Chongqing is shown.

Key words: intelligent transportation, data collection, CDMA, GIS, dynamic traffic data

摘要： 交通数据采集与处理技术是构建智能交通系统的基础。首先通过分析各类交通数据采集技术，提出了基于 CDMA网络实施动态交通数据采集的方法;然后以重庆市主城区为例构建了动态交通数据采集系统;最后结合城市道路交通的特性对数据进行处理，使数据与道路相匹配，并在GIS地图上实现道路交通状态的实时显示。
