碩士 / 中華大學 / 運輸科技與物流管理學系碩士班 / 97 / Because of the advances in medical technology, Taiwan has gradually entered the era of an aging society. In addition, the ratio of elderly to the population in rural areas is higher than that in urban areas. In rural areas, the elderly usually heavily depend on the local public transport system but those systems often can’t meet their needs. Therefore, the main purpose of this study is to design a demand responsive transit system (DRTS) for these senior citizens in rural areas in order to provide better transport service.
Firstly, this study chose the Sigang Township of Tainan County as the implemental case of rural areas. Secondly, a questionnaire survey for Sigang’s elderly was conducted to collect the data of their travel characters and demands, and then an operational model of DRTS was proposed according to the results of the previous survey. This operational model, a pre-reserved many-to-few ride-shared DRTS, is based on the use of official-hired vans and private taxis, and includes the following contents: (1) six specific destinations (Sigang Township Office, Jiali Market, Jiali General Hospital, Madou Market, Madou Sin-Lau Hospital and Chi-Mei Hospital); (2) four service routes (Sigang-line, Jiali-line, Madou-line and Chimei-line); (3) the Sigang-line is served by two free-charged official-hired vans and other lines are served by charged taxis; as well as (4) passengers must make a reservation in advance one day before the day they need to be served. Finally, this study developed a prototype of booking and dispatching system and adopted a series of simulation test.
According to different settings of passenger demand, limitation of routing time, and maximal waiting time, a total of 27 combinations of parameters were particularly implemented 30 times for each combination. Moreover, four indexes, such as reject-rate of reservation, carpool-rate of order, supporting-rate of taxi, and average executive-speed of system, are calculated for evaluating the performance of the proposed prototype. Numerical results show that: (1) the reject-rate is zero; (2) the carpool-rate is low if the maximal waiting time reduced, as well as the carpool-rate is high if the demand increased; (3) the more demand, the higher supporting-rate; (4) the difference of trips between taxis is not significant; and (5) the average executive-speed is under 0.9 seconds. Such a result implies that the propose DRTS model and the computational prototype are full of potential and feasibility in practical applications.
