摘要
城市交通流状态的分析是实现智能交通系统的关键技术之一。其效率和稳定性决定了系统的用户评价和实用性。本文介绍了一个采用GPS探测车进行城市交通流的实时分析算法。该系统主要由网络数据接口、地图匹配等模块组成。通过一些高效的算法,大大加快了对探测车数据的处理,使得在短时间内快速响应成为可能;同时设计了稳定持续的网络接口,减少了由系统中各种因素引起的数据丢失。
The analysis of urban traffic is a key technology to realize the Intelligent Transportation System. The efficiency and stability of it resultedthe usability and evaluation of the system. This paper introduced several algorithms for a real-time urban traffic analysis flow system using the GPS vehicle probe. The system mainly consisted of network interface and map matching module. Through the efficient algorithms, the processing procedure was significantly enhanced. The stable network programming interface also eliminated the loss of data.
