Abstract:

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.

Key words: urban traffic, time space distribution, sample analysis, taxi shift
