| With the trend of urbanization and the increasing number of vehicles, the negativeeffects of urban transportation are increasing while facilitating travel for residents. Theresearches on urban transport problems using taxi GPS data is becoming a hotspot inrecent years. In this paper, the characteristics of taxi traffic and its application researchusing taxi GPS data are studied,mainly in the following aspects：（1）Pretreat the original data, including error analysis of the data, principles andmethods establishment of data processing, data optimization aspects: relevant researchon map matching technology of taxi GPS data including maps of the transverse andlongitudinal matching; Establish taxi GPS data to travel from end recognitiontechnology, the taxi from the end of each trip to identify and visualize rendering the useArcmap:（2）Study the characteristics of taxi transport operating, including on down off thepeak of research, working and non-working passenger duration contrast, peak and flatpeak periods duration contrast, taxi the average distance passenger research, the averagerunning speed of analysis as well as in time and space research taxi empty driving rate,obtained relevant conclusions.（3）Apply cluster analysis techniques in the taxi GPS data application research,combined with the middle traffic zone partition principles and methods, using SPSSsoftware for the Central District of Harbin City Traffic division, and compares thedifferent clustering methods in traffic zoning applicability, finally choose the mostreasonable clustering way to divide Harbin into17middle traffic zone, and theestablishment of traffic in the area of travel and travel expectations cable OD Matrix.（4）Relevant studies set on the setting of taxi stops using GPS data: analyzing thetemporal and spatial distribution characteristics of its passengers of the off points on theYellow River Road of Harbin, establish and Optimize the shortest walking distance taxistand location choice model, and then setting stations with examples.By analyzing the taxi traffic operation characteristics and using the results of theanalysis to divide middle traffic tone and set taxi stops, this study provided data supportand theoretical basis on using taxi GPS data to study traffic characteristics and solve themacroscopic and microscopic traffic problems in traffic planning. |
