【摘要】：隨著我國經(jīng)濟的快速發(fā)展,城市規(guī)模的擴大,社會的汽車化發(fā)展也很迅猛,由此帶來了交通擁擠和交通事故頻發(fā)等社會問題,這些直接或間接引起的社會經(jīng)濟損失、環(huán)境污染和社會效率的降低等問題已經(jīng)成為阻礙社會發(fā)展的重要因素。隨著3G、4G和Wi-Fi等無線網(wǎng)絡(luò)的覆蓋,使用智能手機的用戶越來越多,這為智能手機進行實時數(shù)據(jù)的傳輸和處理提供了便利。根據(jù)艾媒咨詢研究數(shù)據(jù)表明,在2013年下半年,中國手機地圖用戶規(guī)模達到4.20億,增長8.6%,同時在中國智能手機市場操作系統(tǒng)分布狀況方面,Android所占的份額進一步擴大到了74.5%。 在以上的背景下,同時借鑒智能交通系統(tǒng)(Intelligent Transportation System, ITS)的思想,在現(xiàn)有的車輛系統(tǒng)上,通過融合移動互聯(lián)網(wǎng)、通信技術(shù)和終端定位技術(shù)構(gòu)建一套基于Android的道路交通流量地圖服務(wù)誘導(dǎo)系統(tǒng)。在道路上,移動終端使用本客戶端所提供地圖服務(wù)的同時,通過通信網(wǎng)絡(luò)或GPS定位,通過3G、4G或Wi-Fi等無線網(wǎng)絡(luò)上傳自己的經(jīng)緯度、行駛速度、行駛方向、行駛的海拔等信息到服務(wù)器,同時還能上傳特殊交通事件的圖片和描述信息到服務(wù)器,這不僅增加了該事件的可信度,而且方便用戶查看,經(jīng)過服務(wù)器對該數(shù)據(jù)的運算和提取,得到實時的道路交通流量,然后把交通信息反饋給用戶,提高用戶的出行效率。交通信息包括當(dāng)前的交通流量狀況、特殊交通事件、道路的建設(shè)和維修情況以及道路的禁止通行情況等。 本文設(shè)計并實現(xiàn)了交通誘導(dǎo)系統(tǒng)的客戶端,該客戶端是以用戶為中心,為用戶提供了豐富的地圖服務(wù)。從功能上來說,客戶端不但可以上傳數(shù)據(jù)和顯示實時交通流量,還能通過二次開發(fā)Google Maps的地圖服務(wù)為用戶提供了定位信息查詢及顯示、地圖模式切換、基于起點和終點的路徑規(guī)劃、基于途徑地點的路徑規(guī)劃、路線語音導(dǎo)航及終點趨近提醒、查找特定的地點及顯示該地點的詳細信息、周邊感興趣地點查詢及顯示地址和圖片信息、記錄行駛軌跡和距離并能夠動態(tài)顯示在地圖的上面等基于位置的服務(wù)(Location Based Service, LBS),這些功能可以滿足移動終端用戶基本的地圖服務(wù)需求。
[Abstract]:With the rapid development of our country's economy, the expansion of the city scale and the rapid development of the society, there are many social problems, such as traffic congestion and frequent traffic accidents, which are directly or indirectly caused by the social and economic losses. Environmental pollution and the reduction of social efficiency have become an important factor hindering social development. With the coverage of wireless networks such as 3G 4G and Wi-Fi, more and more users are using smart phones, which makes it easy for smartphones to transmit and process real-time data. In the second half of 2013, the number of mobile phone map users in China reached 420 million, an increase of 8.6 percent, while Android's share in the distribution of operating systems in China's smartphone market further expanded to 74.5. Under the above background, using the thought of Intelligent Transportation system (ITSs) for reference at the same time, on the existing vehicle system, through the integration of mobile Internet, A set of road traffic flow map service guidance system based on Android is constructed by communication technology and terminal positioning technology. On the road, while using the map service provided by the client, the mobile terminal uploads its latitude and longitude, travel speed and driving direction through the communication network or GPS location, and through wireless network such as 3G 4G or Wi-Fi. At the same time, it can upload pictures and description information of special traffic events to the server, which not only increases the credibility of the event, but also facilitates the user to view, through the operation and extraction of the data by the server. The real-time traffic flow is obtained, and then the traffic information is fed back to the user to improve the user's travel efficiency. Traffic information includes current traffic flow, special traffic events, road construction and maintenance, and road traffic ban. This paper designs and implements the client of traffic guidance system, which is user-centered and provides rich map service for users. In terms of function, the client can not only upload data and display real-time traffic flow, but also provide users with location information query and display, map mode switching through secondary development of Google Maps map service. Path planning based on starting point and destination, route planning based on path location, route voice navigation and destination approach alert, search for a particular location and display details of the location, Search and display the address and picture information of the surrounding place of interest, The location based Service (LBSN), which records the travel path and distance and can be dynamically displayed on the top of the map, can meet the basic map service requirements of mobile end users.
