摘要分析了网约车计程计时的误差来源,在微波暗室环境下对6种不同场景,4家不同的网约车平台计程计时数据进行检测。结果表明,计时误差均满足规定要求,在高速公路,机场周边,由于卫星信号相对较好,计程误差在-0.4%～1.6%之间;而在市区道路,火车站及工业园区,由于有建筑物遮挡及其他环境的干扰,尤其在市区道路之间,由于经过隧道,导致部分路段出现信号消失的情况,计程误差在-0.4%～5.5%之间;在高速辅路,卫星信号不连续导致轨迹丢失较多,计程误差在2.4%～8.4%之间。

Abstract：To analysis the error sources of app-based ride-hailing calculating mileage and time, 6 different scenes and 4 different app-based ride-hailing service platform calculating mileage and time data are tested in the microwave anechonic chamber environment. The results show that the timing error meets the stipulated requirements, on the highway, around the airport, due to the relatively good satellite signal, the mileage error is -0.4% to 1.6%, while in urban roads, railway stations and industrial parks, due to the interference of buildings and other environments, especially between urban roads, due to passing through the tunnel, with the disappearance of signals on some road sections, the mileage error is -0.4% to 5.5%. In high-speed auxiliary roads, the signal was not continuous, and the mileage error is 2.4% to 8.4%.
