| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 96 === The vacancy rate of taxi continued to raise in the last few years; up to 2006 the taxi vacancy rate of Taipei Metropolitan has already exceeded 70.4%. Different from the past researches focusing on issues of taxi pricing, administrative management, taxi pooling, supply-demand and vacancy rate, this study aims to compare loading strengths of taxi stands with differential ridership possibility and to characterize factors affecting that possibility.
According to the results of previous empirical studies, the time-location factors, such as landuse types and time period, usually affect the mode choice of urban users. This study further examined the interaction between temporal and locational factors, as well as the relationship between factors and passenger loads by applying regression models. The results show that the other factors, such as services of alternative modes, also play a significant part of affecting passenger loads.
Thereafter, this study applied a searching algorithm of modified minimum spanning tree to simulate the best queuing locations for optimizing passengers carrying in different districts of Taipei city. The simulation results reveal that if taxis’ origins at East or West district, they tend to operate in an intra-district pattern; however, those who originate at North or South district prefer to operate crossing districts. In summary, this study shows that time-location factors indeed significantly affect the operating outcome of taxi, and the simulation results can be used as reference for taxi choosing stands by time-location considerations.
