【摘要】：随着中国经济的快速发展和人们生活水平的不断提高,汽车数量呈现出了快速的增长趋势。汽车数量的持续增长在方便了人们出行的同时,也使道路交通需求急剧增长,由此产生的道路交通问题以及衍生的资源浪费、环境污染等问题亟待解决。限制汽车数量增长和不断扩大交通路网规模的方法已经不适应现代社会发展的要求。借助科技手段研发智能交通系统是解决这个问题的有效途径,其中实时交通信息系统的建设是关键。实时交通信息系统可以提供实时的道路交通状况等信息,对道路交通流进行动态引导,从而有效地解决道路交通拥堵问题,同时为用户提供实时交通信息服务极大地方便了用户的出行。本文设计并实现为用户提供交通信息服务的交通信息发布系统。交通信息发布系统由交通信息发布服务器和能够接收交通信息的终端设备两部分组成。交通信息发布服务器负责响应用户终端设备的请求并返回交通信息。接收交通信息的终端设备可以是智能手机、平板电脑、车载导航等,终端设备负责接收、处理交通信息并在终端设备屏幕上显示,为用户提供便利的交通信息服务。本文选择TPEG协议作为交通信息发布协议,研究了TPEG协议的内容,分析了TPEG协议的结构和特点,并且说明了主要的TPEG交通信息的表述方式。设计了交通信息发布服务器的方案,完成了服务器对终端请求处理程序和交通信息发布程序的编写,实现了交通信息发布功能。设计了Android平台下交通信息移动终端软件方案,实现了Android平台下的TPEG协议的交通信息解码,实现了终端设备处理和显示交通信息的功能并能够响应用户的各种操作。最后本文对交通信息发布系统进行了功能测试。测试结果表明交通信息发布系统能够正常工作。交通信息发布服务器能够及时响应终端设备发出的请求并正确返回相应的交通信息；终端设备能够接收、处理并显示交通信息,为用户提供全面便利的交通出行服务。
[Abstract]:With the rapid development of Chinese economy and the improvement of people's living standard, the number of cars is increasing rapidly. The continuous increase of the number of cars not only facilitates people to travel, but also makes the demand for road traffic increase rapidly. The resulting road traffic problems and the resulting waste of resources, environmental pollution and other problems need to be solved. The methods of restricting the growth of the number of cars and expanding the scale of the traffic network are no longer suitable for the development of modern society. It is an effective way to solve this problem by using scientific and technological means to develop intelligent transportation system, and the construction of real-time traffic information system is the key. Real-time traffic information system can provide real-time information such as road traffic condition, and guide the road traffic flow dynamically, so as to effectively solve the problem of road traffic congestion. At the same time, providing users with real-time traffic information services greatly facilitates the travel of users. This paper designs and implements a traffic information publishing system which provides users with traffic information services. The traffic information publishing system consists of two parts: the traffic information issuing server and the terminal equipment which can receive the traffic information. The traffic information publisher is responsible for responding to user terminal equipment requests and returning traffic information. The terminal equipment that receives traffic information can be smart phone, tablet computer, vehicle navigation, etc. The terminal device is responsible for receiving, processing traffic information and displaying it on the terminal device screen, providing convenient traffic information service for users. In this paper, TPEG protocol is chosen as the traffic information publishing protocol, the content of TPEG protocol is studied, the structure and characteristics of TPEG protocol are analyzed, and the main expression methods of TPEG traffic information are explained. The scheme of the traffic information publishing server is designed, the terminal request processing program and the traffic information issuing program are written by the server, and the traffic information publishing function is realized. This paper designs the software scheme of traffic information mobile terminal based on Android platform, realizes the decoding of traffic information under Android platform, realizes the function of terminal equipment processing and displaying traffic information, and can respond to various operations of users. Finally, the function of the traffic information publishing system is tested. The test results show that the traffic information publishing system can work properly. The traffic information publishing server can respond to the request of the terminal equipment and return the corresponding traffic information correctly; the terminal equipment can receive, process and display the traffic information, and provide the users with comprehensive and convenient traffic travel service.
