| Summary: | 碩士 === 國立交通大學 === 運輸與物流管理學系 === 101 === The owner vehicles are increasing every year, it depends on the raised of income and urbanization improvement. Thus, the government has made some transport policies to solve the traffic problems because of reasons as explain earlier. Similarly, economic development, the number of population, income promotion and the number of cars and motorcycles are growing rapidly; consequently, the government has to develop the public transportation systems to reduce the owner vehicles in the network.
The purpose of this research is calculated the variables to impact the intercity public vehicles choices in Taiwan. It provides the suggestions to increase the public transportation used. This research focuses on the 348 townships in Taiwan and the model is divided by the distances such as, short trip (20-50km), long trip (over 50 km). The data come from MOTC survey, and also it uses the Aggregate Logit model to estimate one set of parameters associated with explanatory variables such as generic variables, social-economic variables, private variables and public transportation variables. Additionally, it uses elastic analysis to receive the management strategy of transportation.
As the results, travelers prefer to choose motor rather than public transportation (rail transportation, ground transportation, paratransit) for the short trips within the intercity network. Also in the long trip, travelers prefer to choose car rather than public transportation (rail transportation, ground transportation). The management strategies, both travel costs and travel times are important variables for impact to mode choice of intercity travelers. If travel cost of owner vehicles are increased, the number of owner vehicle users will decrease. In addition, if travel times of public transportation are decreased, the number of public transportation users will increase.
