【摘要】：现今时代，社会经济飞速发展，城镇化的进程也随之而快速推进，伴随而来的是汽车保有量的井喷式发展。汽车骤增带来了城市道路的拥堵和交通事故的发生愈加严重，居民出行难的问题已经成为了社会共性问题，亟待解决。公众对交通信息的渴望，促进了现代交通信息服务技术的全面迅速发展。根据不同的用户需求，如何提供准确而高效的交通信息服务成为了大众关注的热点。日前，政府以及企业主导研究出现的交通信息服务平台显著增加。这些平台的建设急切的需要系统化的理论进行指导和应用性较高的关键技术提供支持。结合近些年智能手机等移动终端设备飞速发展的情况，广大出行用户试图通过移动终端获取相关交通信息服务的需求日益强烈。本文以科研项目为依托，针对移动终端下的交通信息服务技术进行了深刻而广泛的研究。同时，本文设计出了基于移动终端的交通信息服务系统。现对本文的主要工作介绍如下：首先，针对高速公路这一道路群体，设计得出了基于移动终端的高速公路交通信息服务系统。针对该系统的需求进行了可靠的分析，同时设计得到四个功能：位置服务，智能导航，出行管家和动态预警。每一个功能的具体实现，本文也给出了相关的实现流程，从而为类似的研究提供了参考。然后，本文针对交通位置信息获取的技术进行了广泛研究，主要从基于移动终端的无线定位技术以及地图匹配这两个方面进行了研究。先对辅助GPS定位技术的原理，流程和算法进行了简单介绍，然后介绍了RSSI定位技术，最后提出了基于以上两种定位方式的组合定位，并给出了具体定位流程。基于上述定位技术的基础上，本文设计了地图匹配的算法，并对相应的匹配参数和权值进行了确定和验证工作。最后，本文对以移动终端为基础的实时导航技术做了分析，得出结论：良好实时诱导的关键是求解以得到最优路径。进而，简单阐述了蚁群算法基本模型的思想和理论方法，并利用改进的蚁群算法求解了最优路径，同时进行了验证。
[Abstract]:Nowadays, with the rapid development of social economy, the process of urbanization is also advancing rapidly, accompanied by the blowout development of vehicle ownership. The sudden increase of cars has brought more and more serious traffic accidents and congestion on urban roads. The problem of residents' travel difficulty has become a common problem, which needs to be solved urgently. The desire of the public for traffic information has promoted the rapid development of modern traffic information service technology. How to provide accurate and efficient traffic information service has become the focus of public concern. A few days ago, There has been a significant increase in the number of transportation information service platforms emerging from government and business-led research. The construction of these platforms urgently requires systematic theoretical guidance and support from key technologies with high application. The rapid development of mobile terminal devices such as mobile phones, The demand of the vast number of travel users to obtain related traffic information services through mobile terminals is increasingly strong. Based on scientific research projects, this paper makes a profound and extensive research on the technology of traffic information services under mobile terminals. This paper designs a traffic information service system based on mobile terminal. The main work of this paper is as follows:. First of all, a highway traffic information service system based on mobile terminal is designed for the freeway group. The demand of the system is analyzed reliably, and four functions are designed: location service. Intelligent navigation, travel housekeeper and dynamic early warning. The specific implementation of each function, this paper also gives the relevant implementation flow, thus providing a reference for similar research. Then, this paper has carried on the extensive research to the traffic location information acquisition technology, mainly has carried on the research from the mobile terminal wireless localization technology and the map matching these two aspects. First, the principle of the auxiliary GPS localization technology, The flow and algorithm are briefly introduced, and then the RSSI localization technology is introduced. Finally, the combined positioning based on the above two methods is proposed, and the specific positioning flow is given. In this paper, the algorithm of map matching is designed, and the corresponding matching parameters and weights are determined and verified. Finally, this paper analyzes the real-time navigation technology based on mobile terminal, and concludes that the key to good real-time guidance is to get the optimal path. The improved ant colony algorithm is used to solve the optimal path.
