碩士 === 國立交通大學 === 交通運輸研究所 === 99 === Demand Responsive Transit (DRT) is a mode of transportation between mass transportation and private transportation, which is generally suitable for remote areas. The level of services available in the traditional bus service of remote areas in Taiwan, has not only resulted in dissatisfaction from local residents, but also serious losses to traditional bus service owners. Therefore the government must make provisions for substantial financial subsidies. In order to enhance transportation services in remote areas, the Ministry of Transportation and Communication intends to implement DRT as an improvement to traditional bus services. In this case, the Institute of Transportation commissioned a DRT project for setting norms and demonstrating projects in Taoyuan County, Ilan County and Taichung City. As a result of these projects, DRT is mainly based on the advanced equipment combined with telecommunications and internet information management systems, and the use of vans to serve the needs of people in remote areas. However, if an inappropriate type of DRT is implemented this would lead to a waste of costs as high construction costs will be reflected in the fares, and people in remote areas have a lower ability to pay for such means of transportation. As a result DRT will only be a new mode of transportation, but it still cannot meet the needs of people in remote areas. Our research adapts minibuses with 20 seats, vans with 8 seats and passenger cars with 4 seats as DRT vehicles. We apply different types of vehicles operating in various situations to get performance value, and then use performance value to convert costs through the cost analysis model. Further, we use the comparison of cost to define the suitable condition for different DRT types. The suitable condition was defined in accordance to the corridor length and corridor strength of demand in remote area. From conclusions, we know that the suitable condition of minibuses with 20 seats is corridor length between 10km and 40.8km and daily transport demand between 139 and 238 people; the suitable condition of vans with 8 seats is a corridor length between 10km and 40.8km and daily transport demand between 90 and 115 people.
