摘　　要：为解决目前获取路况信息成本高、准确度低的问题,设计并实现一种基于移动终端的路况信息实时采集与显示系统。该系统采集移动终端的速度和方向信息,将其转换为道路上浮动车流量,据此划分交通拥堵状况。系统服务器端以My SQL作为数据库,采用Servlet技术开发,客户端采用j Query Mobile+Html5技术设计为Web App以适应不同的移动设备,交通路况的显示借助于百度地图,数据更新采用AJAX技术。测试结果表明,在4G网络及移动智能终端普及的今天,该系统获取实时路况信息成本低、准确度高,有助于缓解交通拥堵压力,方便人们出行。In order to solve the problems of high cost and low accuracy of traffic information collection, a real-time traffic informa- tion collection and display system based on mobile terminal is designed and implemented. In this system, traffic flow is firstly converted from the moving speed and direction of the mobile terminal, and then is used to grade traffic congestion. The server is designed by Servlet technology, and MySQL is used as database in server. The client is designed as Web App using jQuery Mo- bile ＋ Html5 technology to adapt to different mobile devices. Baidu Map is used to display the traffic flow information in this sys- tem, and AJAX technology is adopted to update the statistics. Testing results show that the system has advantages of low-cost and high-accuracy in getting real-time traffic information based on popular use of 4G network and mobile intelligent terminal, which is helpful to relieve traffic congestion pressure and facilitate people to travel.
