【摘要】 本文介绍了智能交通系统ITS(Intelligent Transportation Systems)的组成。智能交通系统是将先进的信息技术、数据通信传输技术、电子控制技术以及计算机处理技术与先进的行政管理手段结合起来，使其有效地综合运用于交通运输的服务、控制和管理。其目的是使人、车、路密切配合、和谐统一，极大地提高综合交通运输效率，保障交通安全，改善环境质量和提高能源利用率。 文章首先介绍了美、日、欧等国家和地区智能交通的一些发展情况，我国智能交通系统的发展情况。主要从适应智能交通方面，介绍了智能车辆的发展情况，智能交通与智能车辆的关系；世界智能车辆的研究现状，我国智能车辆的研究现状，适应我国智能交通的智能车辆需要具备哪些性能。智能车辆系统(IV：Intelligent Vehicles)利用传感器技术、信号处理技术、通讯技术、计算机技术等，辨识车辆所处的环境和状态，并根据各传感器所得到的信息做出分析和判断，或者给司机发出劝告和报警信息，提请司机注意规避危险；或者在紧急情况下，帮助司机操作车辆(即辅助驾驶系统)，防止事故的发生，使车辆进入一个安全的状态；或者代替司机的操作，实现车辆运行的自动化。智能车辆技术按功能层次可以分为三层，即智能感知／预警系统、车辆驾驶系统和全自动操作系统；智能车辆的研究涉及计算机测量与控制、计算机视觉、传感器数据融合、车辆工程等诸多领域，可以说，智能车辆的研究是计算机视觉与计算机控制研究在车辆工程上的综合。 智能车辆的定位、导航、路径推算、避障是本文的主要内容；主要从机器视觉技术、雷达技术、高精度的数字地图和导航技术，介绍了全球定位系统GPS、车辆组合导航定位、数字地图数据库技术等智能车辆的主要技术，最后得出了适应智能交通系统的智能车辆的模型。智能车辆模型具备定位、导航、避障、信息传递等功能。具备了这些功能的智能车辆能更好的满足智能交通的需要，从而达到缓解交通压力，提高运输效率，提高车辆的安全性能的目的。更多还原

【Abstract】 This article introduced intelligence transportation system ITS (Intelligent Transportation Systems). The intelligence transportation system is the advanced information technology, the data communication transmission technology, the electronic control technology as- well as the computer processing technology and the advanced administration method unifies, causes its effectively to synthesize utilizes to the transportation service, the control and the management. Its goal is causes the person, the vehicle, the road close coordination, the harmonious unification, enormously enhances the synthesis transportation efficiency, the safeguard traffic safety, the improvement environment quality and raises the energy use factor. The article first introduced national and the local intelligence transportation and so on America, date, Europe some development situations, our country intelligence transportation system development situation. Mainly from the adaption intelligence transportation aspect, briefed,,the intelligent vehicles development situation, the intelligent transportation and the intelligent vehicles relations; The world intelligence vehicles research present situation, does our country intelligence vehicles research present situation, which performance adapt our country intelligence transportation intelligent vehicles to need to have. Intelligent vehicles system (IV: Intelligent Vehicles) uses the sensor technology, the signal . processing technology, the communication technology, the computer technology and so on, recognizes environment and condition which the vehicles locates, and the information which obtained arrives according to various sensors makes the analysis and the judgement, or sends out to the driver advises and reports to the police the information, proposes the driver to pay attention dodges the danger; Or in the emergency case, helps the driver to operate the vehicles (namely assistance control loop), prevented the accident the occurrence, causes the vehicles to enter a safe condition; Or replaces driver’s operation, realizes thevehicles movement automation. The intelligent vehicles technology may divide into three according to the function level, namely intelligent sensation/early warning system, vehicles control loop and entire automatic operating system; The intelligent vehicles research involves the computer survey and the control, the computer vision, the sensor data fusion, the vehicles project and so on many domains, may say, the intelligent vehicles research is the computer vision and the computer control research in the vehicles project synthesis. The intelligent vehicles localization, the navigation, the way calculated, evades bonds is the this article main content; Mainly from the machine vision technology, the radar technology, the high accuracy digital map and the navigation technology satellite, introduced global positioning system GPS, the vehicles combined navigation localization, intelligence and so on digital map data bank technology comes out the main technology, finally has obtained the adapt ion intelligence transportation system intelligent vehicles model. The intelligent vehicles model has the localization, the navigation, evades bonds, function and so on information transmission.Had these functions intelligent vehicles to be able the better satisfied intelligent transportation need, thus achieved alleviated the traffic pressure, enhanced the transportation efficiency, enhanced the vehicles the security performance goal.更多还原
