Taking Santana as the standard car, on the basis of a great deal of GPS data, this paper studies acceleration characteristics of starting vehicles, and developed the acceleration statistic model of starting vehicles in free flow.

• 本文以普通桑塔纳为基准车型,以大量gps实测数据为分析基础,研究了车辆在自由状态下从速度为0一直加速到期望车速的整个过程,建立起在自由流状态下的车辆启动加速统计分析模型。
