摘要
基于GPS定位的浮动车交通信息采集的关键问题之一就是如何确定浮动车的样本数量,分析在不同交通参数检测需求下,浮动车样本数量的确定方法,同时在考虑定位精度和通信效率下,给出计算模型,具有重要的应用价值。
One major problem of GPS equipped probe vehicle traffic information collection is how to determine probe vehicle sample sizes. Based on requirements of different traffic parameters measurements,methods of determining probe vehicle sample sizes are analyzed. Considering the precision of positioning and efficiency of correspondence, a calculative model is given and it has an important application value.
