Study on Positioning and Mileage Error in Carhailing Service based on the GNSS Traces

摘要

In recent years, car-hailing service has been rapidly developed in China, especially in the first tier cities such as Beijing, Shanghai and Guangzhou. The charge of car-hailing service is based on the service mileage. Therefore, it is important for the car-hailing service platform to calculate the service mileage accurately. In a given period of time, the service mileage equals to the summary of distance between adjacent positioning coordinates. In this paper, a research is made to study the relationship between the positioning error of adjacent positioning coordinate and the error of corresponding mileage. Vehicle experiment is carried out in five kinds of typical road conditions, which contains "elevated road above", "elevated road below","tunnel", "shade" and "open-air". The results show that the difference between the positioning error of adjacent point has great influence on the cooresponding mileage error in the same period.
