摘要
安装了GPS的出租车可实现大范围、全天候的车辆行驶数据采集,这些量大、时刻变化的GPS轨迹数据记录了城市交通、人群移动的动态变化信息,对研究城市交通起着重要的意义.从研究基于数据驱动的智能交通角度出发,综述国内外基于出租车GPS轨迹大数据的城市智能交通研究现状,经过归纳总结,将目前的研究工作分为交通状态分析、运营管理及支持、路径规划及预测三个方面,总结并阐述出租车GPS轨迹大数据在这三个方面的研究及应用情况,并指出该领域目前面临的问题和不足以及进一步需要研究的方向.
Large-scope and all-weather data acquisition of vehicle travel can be realized by taxis installed with GPS, which can record massive and time-varying data of GPS trajectory of dynamic variation information of urban traffic and crowd, playing an important role in investigating urban traffic. With the view of investigation of data-driven intelligent traffic, the current situation of investigation of urban intelligent traffic based on taxi GPS big trajectory data at home and abroad is summarized and, by means of induction, the present research is divided into such three aspects as traffic situation analyzing, operation managing and supporting, and path planning and forecasting; and the research and application of taxi GPS trajectory data in connection with these three aspects are summed up and expounded and the problems faced currently by this field and the development direction of required investigation are also pointed out.
