摘要
基于GPS的测试车采集行程时间的方法,具有操作方便、资料丰富和精度高的优点。研究了利用GPS数据计算行程时间的两种方法———端点时间差法和速度积分法,并进行了比较研究,同时还给出了一个实际案例。结果表明,基于GPS的测试车方法采集的行程时间具有较高的精度。
Test vehicle technique based on GPS to collect travel time has such merits as simple operation, detailed data and high accuracy. Two methods, time difference between nodes and speed integration, to acquire travel time based on GPS data were compared and one case was given. The results show that test vehicle technique based on GPS has the merits of high accuracy.
