摘要
在分析目前城市交通信息采集系统中存在的检测成本高、检测范围有限等主要问题的基础上,提出通过GPS/蜂窝无线定位进行交通信息实时采集处理的新方法,深入剖析了该方法的技术关键,并给出该方法的测算效率改进模型,结果显示本文模型相对原有模型改进了5%以上。
High cost and low efficiency of measurement are the main problems of urban traffic information collection system. Based on the analysis of these problems, this paper discusses the traffic information collecting technology based on GPS/Cell wireless location. Analyzing the characteristics and difficulties of this approach, this paper also reasons the modified (efficiency) calculating model. The result shows the efficiency is promoted above 5 percent.
