摘要
出租汽车GPS数据记录了车辆的出行轨迹、时间、起讫点等信息,利用相关算法可以挖掘车辆或乘客的运行特征、时空分布特征等,应用于交通规划和运营管理。在总结出租汽车GPS异常数据的处理方法以及时空分布特征主要算法的基础上,对广州市约2万辆出租汽车的上下客流热点区域、时间分布、OD分布等进行总结。以广州市为例进行实证研究,从交通规划、运营管理、服务模式等方面选择典型案例,剖析广佛出租汽车返程点布局规划、公共汽(电)车夜班线路优化,以及如约巴士+出租汽车新服务模式的应用尝试。
The taxi GPS data,containing travel path,time,origin and destination(OD)and etc.,can be used to reveal a passenger travel characteristics in spatial and temporal terms,which is valuable to the transportation planning and traffic operation management.This paper presents a case study that analyzed the GPS data from 20,000 taxies in Guangzhou,which clearly reveals the passenger hot spots,temporal distribution,OD distribution.This real world case study provides the empirical evidence not only to the Guangzhou transportation planning and operational management but also for optimizing night-time public transit service routes as well as new combined service of paratransit and taxi.
