碩士 / 國立交通大學 / 運輸與物流管理學系 / 101 / With GDP growing rapidly, ownerships and uses of private vehicles have increased dramatically and have worsened traffic situation. Road transportation systems, especially private vehicles are highly dependent on fuel and result in environmental pollutions. Therefore, how to develop public transportation to elevate transportation efficiency has become an important issue.
The purpose of this study is to examine the impacts of urban form on operational efficiency of mass transit by using, 19 cities in East Asian as sample. This study began with a cluster analysis to categorize the sample cities into two groups, the following criteria: population density, GDP per capital and proportion of aging population. Then, this study applied Data Envelopment Analysis to evaluate the relative efficiencies of the sample cities in two groups. Finally, the factors affecting operational efficiency of mass transit were explored by Tobit regression model, and considerable strategies of urban form were drawn based on the empirical evidence.
The major empirical findings are as follows: (1) The sample cities can be categorized into two groups: developed cities and developing cities. (2) The results of DEA show that operational efficiencies of the developed cities were significantly higher than that of the developing cities, and the pure technique efficiency is the highest index among all efficiency indexes. (3) Most sample cities were in the phase of decreasing returns to scale and they need to improve their effectiveness by decreasing inputs of mass transit systems. (4) The results of Tobit regressions indicate that the environment variables result in different effects on operational efficiencies between the two city groups.
