| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 100 === For development of demand responsive transit service (DRTS), there are many influence factors such as social and economic condition, demographic composition, transportation demand characteristics and available transportation services. Analyzing the circumstance for application of DRTS is crucial to determine if a specific region has the potential to implement the new transportation system. In this study, mathematical models of conventional bus, DRTS and automobile are developed and used to analyze appropriate thresholds and circumstances for DRTS while minimum social total cost is considered as the objective function. Moreover, numerical examples are used to verify the applicability of model. Sensitive analysis has also been conducted to evaluate the effects of important parameters on the application environment for DRTS, such as demand density, value of time, and operating cost. Results of this study could help to identify in which circumstance DRTS is more preferable to automobile and conventional bus service in terms of demand density and other environment factors.
