【摘要】：交通是社会、经济活动的动脉和纽带,对社会经济发展和人民生活水平的提高起着非常重要的作用。近年来,随着经济的高速发展,交通基础设施建设虽然在不断扩张,但交通状况仍然在日益恶化,交通安全形势也异常严峻,交通拥堵更是大中城市交通中的普遍现象。这也充分说明了交通设施利用率比较低下,交通管理技术相对落后以及智能化程度亟待进一步提高等。针对现有交通系统仅包含静态信息,用户体验不佳,创新性不够等问题,设计与实现了基于iOS的智能交通系统。基于iOS的智能交通系统是一款致力于提升行人交通出行效率的公共交通服务软件,它将静态交通信息和动态车辆位置信息有机结合,方便了乘客安排出行计划和出行时间,改善了交通的运行状况。系统很好的满足了人们对交通运输系统的需求,并且对智能交通系统的研究和发展具有指导性作用。基于iOS的智能交通系统采用的是C/S结构模式,包括服务器端、iOS客户端、交通监控中心系统、网络通信等部分。(1)服务器端使用轻量级的JFinal框架和MySQL数据库,用于接收用户的请求,进行处理并把请求数据信息返回到客户端；(2)iOS客户端采用高内聚、低耦合的模块化设计思想,用于和用户交互,接收用户的输入搜索请求,并把请求信息发送给服务器端,获得用户所需数据后再以一个友好的方式展现给用户；(3)交通监控中心系统的车载终端设备实时采集车辆的GPS位置信息并传输给交通监控服务中心,交通监控服务中心把车辆数据信息发送到服务器端的数据库中；(4)网络通信则采用HTTP通信协议,使用JSON数据交换格式,并应用基于DES和RSA的混合加密体制,实现客户端和服务器之间安全可靠的数据信息传输。系统经过一系列的功能性测试和稳定性测试,符合当初系统的设计需求,运行期间的稳定性和可靠性都能达到标准,平均1.0s的查询速度也比较理想。智能交通系统的功能强大,结构简单,方便实用,稳定性好,不仅提高了乘客的出行效率,极大地改善了用户的出行体验,而且推动了智能交通系统的进步,是交通运输行业智能化发展的又一个具有里程碑意义的重大突破。
[Abstract]:Transportation is the artery and tie of social and economic activities, which plays a very important role in the development of social economy and the improvement of people's living standard. In recent years, with the rapid development of economy, traffic infrastructure construction is expanding, but the traffic situation is still deteriorating day by day, the traffic safety situation is also extremely severe, traffic congestion is a common phenomenon in large and medium-sized cities. It also shows that the utilization ratio of traffic facilities is relatively low, the traffic management technology is relatively backward, and the degree of intelligence needs to be further improved. Aiming at the problems that the existing transportation system only contains static information, the user experience is not good and the innovation is not enough, the intelligent transportation system based on iOS is designed and implemented. Intelligent Transportation system (its) based on iOS is a public transportation service software dedicated to improving pedestrian traffic travel efficiency. It organically combines static traffic information with dynamic vehicle location information to facilitate passengers to arrange travel planning and travel time. Improved traffic conditions. The system meets the needs of transportation system, and has a guiding effect on the research and development of intelligent transportation system. The intelligent transportation system based on iOS adopts C / S structure mode, including server, iOS client, traffic monitoring center system, network communication and so on. (1) the server uses lightweight JFinal framework and MySQL database. For receiving a user's request, processing and returning the request data information to the client; (2) the iOS client adopts the modular design idea of high cohesion and low coupling, which is used to interact with the user, receive the user's input search request, and send the request information to the server. After obtaining the data required by the user, it will be presented to the user in a friendly manner. (3) the vehicle terminal equipment of the traffic monitoring center system collects the GPS position information of the vehicle in real time and transmits it to the traffic monitoring service center, which sends the vehicle data information to the database on the server side; (4) the network communication adopts HTTP protocol, uses JSON data exchange format, and uses the mixed encryption system based on DES and RSA to realize the secure and reliable data transmission between client and server. After a series of functional tests and stability tests, the system meets the design requirements of the original system, the stability and reliability of the system during operation can reach the standard, and the average query speed of 1.0s is also ideal. The intelligent transportation system has powerful function, simple structure, convenient and practical, and good stability. It not only improves the travel efficiency of passengers, greatly improves the travel experience of users, but also promotes the progress of intelligent transportation system. It is another milestone breakthrough in the intelligent development of transportation industry.
