【摘要】：自从GPS等定位服务出现以来,地理位置信息被广泛得应用于军事,通信等各种各样的软件应用中。随着定位技术的不断发展,通过传感器获得地理位置变得越来越轻量化,定位也越来越准确。各地政府和公司已经越来越重视定位系统在公共交通领域的应用,以达到更好的管理交通线路,为用户提供更全面的帮助等目的。目前,越来越多的公交车等公共交通工具上安装了定位传感器,并实时得向后台更新位置信息。公交公司通常会利用实时的车辆信息来调度公交车,规划线路,检测事故等。然而普通乘客却很少有机会能获得公交的实时信息。本篇论文所涉及的项目是一个通过进一步利用公交实时的地理位置信息,配合上本身公交系统中的路线,时刻表等静态信息,来给用户提供更好的出行帮助和导航的手机应用。相比于其他的公交应用,本项目大范围应用了公交实时信息,为用户提供更为动态和智能的出行帮助。应用中包含了旅程搜索,动态旅程,时刻表,收藏等基本功能模块。其中动态旅程中应用了间断数据连续化算法来通过间隔更新的车辆位置模拟持续移动的公交车。在用户引导中利用了基于点与多边形距离的算法来简化路线更新,并且利用实时公交信息和用户当前路线比对来反馈用户的状态。应用也会根据用户在使用该程序时的行为习惯来简历速度分布模型以提供更加准确的时间分析。整个应用通过对实时信息和通过对实时公交信息和用户当前状态的结合和分析来全面分析当前行程的关键时间点,可行性等要素,帮助用户获得并利用实时的公交信息。该项目是瑞典爱立信和公交公司?stg?ta Trafiken公司合作开发的,整个系统包括IOS,安卓等前台和提供各类接口和大数据分析的后台系统。本论文主要只涉及IOS应用部分。
[Abstract]:Since the emergence of location services such as GPS, geographical location information has been widely used in military, communications and other software applications. With the development of positioning technology, it becomes more and more lightweight and accurate to obtain geographical location through sensors. Local governments and companies have paid more and more attention to the application of positioning systems in the field of public transport, in order to better manage the traffic lines and provide users with more comprehensive help. At present, more and more public vehicles, such as buses, install location sensors, and update the location information to the background in real time. Public transport companies usually use real-time vehicle information to schedule buses, plan routes, detect accidents, and so on. But ordinary passengers have little chance of getting real-time information about public transport. The project involved in this paper is a mobile phone application which can provide users with better travel assistance and navigation by further utilizing the real-time geographic location information of public transport and matching the static information such as route and timetable in the public transport system. Compared with other bus applications, this project uses real-time bus information to provide users with more dynamic and intelligent travel assistance. The application includes basic function modules such as journey search, dynamic journey, timetable, collection and so on. The discontinuous data continuity algorithm is used in the dynamic journey to simulate the continuously moving bus through the updated vehicle position. An algorithm based on the distance between point and polygon is used to simplify the route updating, and the real-time bus information and the current route alignment are used to feedback the user's status. The application also provides a more accurate time analysis based on the user's behavior in using the program. Through the analysis of real-time information and the combination and analysis of real-time bus information and user's current state, the whole application can comprehensively analyze the key points and feasibility of the current travel, so as to help the users to obtain and utilize real-time public transport information. The project was developed in partnership with Swedish Ericsson and bus company stg?ta Trafiken. The entire system includes IOS, Android and a variety of interfaces and big data analysis of the background system. This thesis is mainly concerned with the application of IOS.
