智能交通系统(ITS)信息采集技术评述

实时交通信息是实现城市交通智能化的关键，是ITS各子系统实施的核心基础数据和重要前提，在交通规划和交通管理控制等方面具有广泛的应用前景。有效利用实时交通信息是智能交通系统中最基础、最重要的组成部分，介绍了用于驾驶员信息和交通控制系统的路边及中枢设备和应用便携式计算机对车速及延误进行采集处理两种信息采集技术，探讨了系统的辅助功能及其相互影响，对应用试验车采集车速和延误的软硬件系统以及分析数据采集概念进行了论述。

Discussion of intelligent transportation systems (ITS) information collection technology

Real-time traffic information is the key to urban intelligentized transportation, and has wide applications in transportation planning and TMC utilities. Therefore, we identify in this paper the requirements and characteristics of roadside equipment and central installations necessary to realize and support the functions. In this context synergetic effects are highlighted by showing that many subfunctions as well as most physical units support more than one function. This paper also describes the hardware and software components of a system designed to collect speed and delay data using a moving vehicle and the data collection concept. All of these are necessary to realize and support the functions of ITS system.
