基于GPS轨迹时空特征的长途客车站外违规载客点自动识别系统研究

摘要

部分区域的长途客车在运营时，存在在规定的停靠站点外上下旅客的违规行为，带来严重的安全隐患，现有车辆动态监控系统无法识别这种违规行为。本文提出了一种基于车辆GPS轨迹时空特征的长途客车站外违规载客点自动识别方法，开发了可视化系统，通过结合深圳市长途客车实际GPS数据的案例分析，验证了方法的准确性和有效性。%In some regions,intercity bus staffs would pick up passengers outside of the scheduled bus stations and pocket the ticket money. Such il egal act brings large potential safety risks. The alert functions offered by the current vehicle tracking systems barely can catch the il egal act. We propose an approach to automatical y detecting suspected il egal pick-up locations from GPS traces, and implement the approach in a geographical information system. A case study demonstrates the effectiveness of the system with its high accuracy of detecting il egal pick-up locations, as wel as its functionality to help understand il egal pick-up behavior and plan on-site investigation.
