【摘要】：交通是社會、經(jīng)濟(jì)活動的動脈和紐帶,對社會經(jīng)濟(jì)發(fā)展和人民生活水平的提高起著非常重要的作用。近年來,隨著經(jīng)濟(jì)的高速發(fā)展,交通基礎(chǔ)設(shè)施建設(shè)雖然在不斷擴(kuò)張,但交通狀況仍然在日益惡化,交通安全形勢也異常嚴(yán)峻,交通擁堵更是大中城市交通中的普遍現(xiàn)象。這也充分說明了交通設(shè)施利用率比較低下,交通管理技術(shù)相對落后以及智能化程度亟待進(jìn)一步提高等。針對現(xiàn)有交通系統(tǒng)僅包含靜態(tài)信息,用戶體驗(yàn)不佳,創(chuàng)新性不夠等問題,設(shè)計(jì)與實(shí)現(xiàn)了基于iOS的智能交通系統(tǒng)�；趇OS的智能交通系統(tǒng)是一款致力于提升行人交通出行效率的公共交通服務(wù)軟件,它將靜態(tài)交通信息和動態(tài)車輛位置信息有機(jī)結(jié)合,方便了乘客安排出行計(jì)劃和出行時(shí)間,改善了交通的運(yùn)行狀況。系統(tǒng)很好的滿足了人們對交通運(yùn)輸系統(tǒng)的需求,并且對智能交通系統(tǒng)的研究和發(fā)展具有指導(dǎo)性作用�；趇OS的智能交通系統(tǒng)采用的是C/S結(jié)構(gòu)模式,包括服務(wù)器端、iOS客戶端、交通監(jiān)控中心系統(tǒng)、網(wǎng)絡(luò)通信等部分。(1)服務(wù)器端使用輕量級的JFinal框架和MySQL數(shù)據(jù)庫,用于接收用戶的請求,進(jìn)行處理并把請求數(shù)據(jù)信息返回到客戶端；(2)iOS客戶端采用高內(nèi)聚、低耦合的模塊化設(shè)計(jì)思想,用于和用戶交互,接收用戶的輸入搜索請求,并把請求信息發(fā)送給服務(wù)器端,獲得用戶所需數(shù)據(jù)后再以一個(gè)友好的方式展現(xiàn)給用戶；(3)交通監(jiān)控中心系統(tǒng)的車載終端設(shè)備實(shí)時(shí)采集車輛的GPS位置信息并傳輸給交通監(jiān)控服務(wù)中心,交通監(jiān)控服務(wù)中心把車輛數(shù)據(jù)信息發(fā)送到服務(wù)器端的數(shù)據(jù)庫中；(4)網(wǎng)絡(luò)通信則采用HTTP通信協(xié)議,使用JSON數(shù)據(jù)交換格式,并應(yīng)用基于DES和RSA的混合加密體制,實(shí)現(xiàn)客戶端和服務(wù)器之間安全可靠的數(shù)據(jù)信息傳輸。系統(tǒng)經(jīng)過一系列的功能性測試和穩(wěn)定性測試,符合當(dāng)初系統(tǒng)的設(shè)計(jì)需求,運(yùn)行期間的穩(wěn)定性和可靠性都能達(dá)到標(biāo)準(zhǔn),平均1.0s的查詢速度也比較理想。智能交通系統(tǒng)的功能強(qiáng)大,結(jié)構(gòu)簡單,方便實(shí)用,穩(wěn)定性好,不僅提高了乘客的出行效率,極大地改善了用戶的出行體驗(yàn),而且推動了智能交通系統(tǒng)的進(jìn)步,是交通運(yùn)輸行業(yè)智能化發(fā)展的又一個(gè)具有里程碑意義的重大突破。
[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.
