|
摘要
随着社会经济的发展,城市化、汽车化速度的加快,无论是发达国家,还是发展中国家,都毫无例外地承受着不断加剧的交通问题的困扰。在此背景下,为了缓解经济发展带来的交通运输方面的压力,尽可能地利用现有的资源,使其发挥最大的作用,各国都加大了对智能交通系统的研究和建设的力度。
车—路和车—车之间的无线通信系统作为智能交通系统发展的重要部分越来越受到人们的关注,该系统主要是在相邻的车辆之间,或者在车辆和路边的基础设施之间交换、提供与驾驶安全相关的信息,扩大司机的视野,从而帮助司机实现安全驾驶,减少城市交通伤亡。
本文首先概述了智能交通系统；介绍了针对车辆通信网络的IEEE 802.11p标准、IEEE 1609标准,及车辆通信网络的组成；然后介绍了基于这些标准下的车—车间安全通信的无线传播范围要求；并介绍了车—车间无线安全通信的相关模型；通过对一个已知模型的修改,得到了一个新的车—车间无线通信传播模型并对新模型进行了仿真。仿真结果表明,新模型不仅满足车—车间无线通信安全要求,而且与实际交通场景更为接近,因此对进一步研究车—车间无线通信有积极作用。
最后,车—车间无线通信作为新兴的研究方向,必然存在着很多的问题,文章列出了新模型未解决的一些问题,同时也指出了下一步的研究方向。
With the development of society and economy and with the acceleration of urbanization and motorization, all the countries, whether developed or developing, are undoubtedly troubled by increasing traffic problems. Under this background, in order to relieve the traffic pressure caused by the economic development, every country strengthens the research and construction in intelligent transportation system, making full use of the current resources to play their biggest role.
As an important part of the intelligent transportation system, the wireless communication system of vehicle-to-road and vehicle-to-vehicle has been paid more and more attention. The system exchanges and provides the related information about safe driving mainly between neighboring vehicles or between vehicles and roadside infrastructure to improve drivers'vision, help drivers to drive safely and reduce the traffic casualties in cities.
This paper outlines the intelligent transportation system, and then for vehicle communication network it introduces IEEE 802.11p standard, IEEE 1609 standard and the composition of vehicle communication network. On the basis of these standards, the safe requirements of vehicle-to-vehicle wireless communication are included. After the related model of safe communication between vehicles is introduced, a new wireless propagation model for vehicle-to-vehicle communication is got and simulated by modifying a known model. The simulation result shows that the new model not only meets the safety requirements of vehicle-to-vehicle wireless communication, but also resembles the real traffic scenes. Therefore, it will have a positive effect on the further study of vehicle-to-vehicle wireless communication.
Finally, as a new research direction, the vehicle-to-vehicle wireless communication system certainly has many problems, and the paper lists some of them which have not been solved in the new model. At the same time, it also points out the direction for future research.
