智能交通系统中的数据处理与分析

智能交通系统是以提高路网通行效率、提高道路利用率、减少交通事故为目的,利用交通信息系统、通讯网络、定位系统和智能化分析与选线的交通系统的总称。文章以天津市智能交通示范工程为背景设计开发交通数据信息分析系统,讨论交通数据的组织形式、查询方式和查询结果的表示方法。该系统对由激光传感器采集的车高、车速和车型数据进行分析处理,提供给用户多种查询方法,并以表格、图形等多种方式展示查询的结果,帮助用户更好的了解交通状况,从而为科学决策提供依据。

The Process and Analysis of Data in the Intelligent Transportation System

Intelligent Transportation System is a system which utilizes traffic information system,communication network, positioning system and transportation of intelligently analyzing and path-selecting,with the aim of improving the efficiency and usability of road networks while reducing traffic accidents.In this article,we discuss the ways to organize, query and display traffic information,based on the Tianjin Intelligent Transportation System,which analyzes and processes the height,velocity and model information of the traffic vehicles collected by the laser sensors,provides user various of query approaches,and finally presents the query result in various modes such as figures,tables and charts, helping user obtain a better appreciation of the current traffic conditions,which in turn gives the user evidence to make further decisions.
