碩士 / 國立交通大學 / 交通運輸研究所 / 99 / The rapid economic growth in Taiwan leads to the severe deterioration of the level of service of road, and excess delays, energy consumption and emissions. In order to improve such a condition, the Ministry of Transportation and Communications (MOTC) implemented several public transportation improvement strategies, including The Alternatives for Promoting the Development of Public Transportation and The Statutes for Public Transportation Development during 1996-2002. Although the public transportation in some urban areas has been significantly improved, the public transportation in rural areas with sparsely population and low transport, demand till suffering from seriously operation deficit and low patronage problems.
Based on this, this study proposes an integrated bi-level mathematic programming model for the optimal subsidy allocation and service planning for rural area transit service. The upper level assumes the subsidy is allocated by the central government to different local governments under a subsidy budget constraint; while the lower level is for local government to plan the optimal transit service for the rural areas in its jurisdiction based on the allocated subsidy to maximize its transit usage rate. Two objective functions in the upper level are considered: fairness (to minimize the differences in transit usage rate among areas) and efficiency (to maximize the aggregate transit usage rate). Different transit service types are considered: fixed-route direct bus service, fixed-route hub-and-spoke bus service and flexible bus service. Residents in rural area choose among these transit modes and private vehicles (cars) based on a mode choice Logit model. To simplify the solution algorithms to the proposed model, the decisions of the upper level are replaced by several commonly adopted subsidy allocation strategies while a genetic algorithm is used to solve the lower level problem (to determine the optimal combination of transit services). A case study on an exemplified example is conducted to examine the applicability of the proposed model. Results show that different optimal transit services are solved in different rural areas depending upon their population densities and the fairness and efficiency indices of different subsidy allocation strategies are also compared. At last, the effects of key parameters are further investigated by sensitive analyses.
