【摘要】：随着我国经济的快速发展,城市规模的扩大,社会的汽车化发展也很迅猛,由此带来了交通拥挤和交通事故频发等社会问题,这些直接或间接引起的社会经济损失、环境污染和社会效率的降低等问题已经成为阻碍社会发展的重要因素。随着3G、4G和Wi-Fi等无线网络的覆盖,使用智能手机的用户越来越多,这为智能手机进行实时数据的传输和处理提供了便利。根据艾媒咨询研究数据表明,在2013年下半年,中国手机地图用户规模达到4.20亿,增长8.6%,同时在中国智能手机市场操作系统分布状况方面,Android所占的份额进一步扩大到了74.5%。在以上的背景下,同时借鉴智能交通系统(Intelligent Transportation System, ITS)的思想,在现有的车辆系统上,通过融合移动互联网、通信技术和终端定位技术构建一套基于Android的道路交通流量地图服务诱导系统。在道路上,移动终端使用本客户端所提供地图服务的同时,通过通信网络或GPS定位,通过3G、4G或Wi-Fi等无线网络上传自己的经纬度、行驶速度、行驶方向、行驶的海拔等信息到服务器,同时还能上传特殊交通事件的图片和描述信息到服务器,这不仅增加了该事件的可信度,而且方便用户查看,经过服务器对该数据的运算和提取,得到实时的道路交通流量,然后把交通信息反馈给用户,提高用户的出行效率。交通信息包括当前的交通流量状况、特殊交通事件、道路的建设和维修情况以及道路的禁止通行情况等。本文设计并实现了交通诱导系统的客户端,该客户端是以用户为中心,为用户提供了丰富的地图服务。从功能上来说,客户端不但可以上传数据和显示实时交通流量,还能通过二次开发Google Maps的地图服务为用户提供了定位信息查询及显示、地图模式切换、基于起点和终点的路径规划、基于途径地点的路径规划、路线语音导航及终点趋近提醒、查找特定的地点及显示该地点的详细信息、周边感兴趣地点查询及显示地址和图片信息、记录行驶轨迹和距离并能够动态显示在地图的上面等基于位置的服务(Location Based Service, LBS),这些功能可以满足移动终端用户基本的地图服务需求。
[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.
