一种基于出租车轨迹数据的优质客源评价模型及实证研究
A model of high quality passenger based on taxi trajectory and case verification
摘要
Abstract
Taking taxi trajectory as the research object,a new high efficiency passenger model based on taxi trajectory is proposed and constructed.The model redefines a complete taxi trip and adopts the profit of taxi in per unit time to quantify the trip.In order to calculate the dynamitic cost of taxi in different situation,the relationship between travel speed and the cost (mainly refers to fuel consumption)of taxi is introduced.Taking the taxi data of May 2015 in Fuzhou as an example,the pre-process and density calculation of the trajectory data were carried out according to the model.The spatio-temporal distribution of the high efficiency passengers is analyzed.The result shows that the model can quantify the taxi source and provide a scientific basis for analyzing the spatio-temporal distribution of taxis.关键词
