实际运营中,公交车辆服务的线路编号调整频率高,而在车辆信息表中存在更新不及时及只增加不删除的情况,极大地影响了结合GPS数据匹配上车站点方法的准确性。本文提出了一种基于公交GPS到离站数据的线路校核方法,首先根据距离最近原则为每条公交GPS到离站数据匹配上车站点,并对途经该上车站点的线路号计数一次;然后按照车辆编号对GPS到离站数据进行分组,分别统计各组中,线路号计数值最大的线路号,以此作为该车辆编号的校核线路;最后根据GPS数据点、原始线路、校核线路进行抽样人工复核,验证校核的准确度。案例数据表明,校核有效率高达98%,并将人工检查的比例降至20%以下,在保证准确度的同时提高了处理效率。
In actual operation, bus service line number adjustment frequency is high, but there is not updated in the vehicle information table and only increase does not delete, greatly affecting the accuracy of the GPS data matching on boarding station method. In this paper, we propose a method of line checking based on the GPS data from the bus to the station. First, according to the nearest distance principle, the GPS to the departure data of each bus is matched to the bus stop, and the route number passing through the bus stop is counted once. And then according to the vehicle number to GPS to leave the data grouping, respectively, statistics of each group, the line number of the largest count of lines, as the vehicle number of the check line; Finally, according to GPS data points, the original line, check Line sampling manual review to verify the accuracy of the check. Case data show that the efficiency of the check up to 98%, and the proportion of manual inspection dropped to 20%, while ensuring accuracy and improve processing efficiency.
