摘要
随着经济社会和城市建设的发展,出租车出行供需矛盾和运营服务水平不高的问题日益突出,有必要对出租汽车的运营特征,尤其是出租车交接班行为特征进行深入地分析,正确评估出租车交接班行为对出租车供给能力的影响.本文以北京市出租汽车数据为例,利用出租车交接班分析算法,研究了出租汽车的交接班时空分布特征.以交接班车辆数、交接班车辆比例和交接班覆盖强度为指标,采用样本分析的方法,研究结果表明:交接班车辆数在一天中的时变规律与出行需求变化基本一致,上午10时至晚22时,交接班车辆数均处于相对较低的水平;交接班地点大都集中在进出京高速公路的周边,呈现出明显的区域集中特性;交接班的时间间隔对交接班的时空分布影响明显.
With the development of economic society and urban construction,it is outstanding that the disequilibrium of taxi supply-demand and low services level.It is essential that researches on characteristics of taxi operation,especially on taxi shift,which will contribute to observe taxi shift affects the supplying ability of taxi.Based on Beijing taxi data and spatial analysis algorithm for taxi shift,three indexes,which are the amount of vehicles for taxi shift,the percent of vehicles for taxi shift and detecting intensity for taxi shift,are designed to analyze the time space distribution characteristic of taxi shift by sample analysis.The result shows that the variation of the amount of vehicles for taxi shift in the day consistent with the change of travel demand,which the amount of vehicles for taxi shift are in the low level from 10 a.m.to 10 p.m.Location for taxi shift lies in the area around the freeway,which had significant area-central character.It is obvious that interval for taxi shift affect the time space distribution of taxi shift.
