Abstract
Aging society gives rise to the problem of resource allocation in a country in the future. Taiwan, currently, is facing this challenge with a high proportion of aging population reaching 11.53% in 2013, which is faster than developed occidental countries in the aging process. A stable social mobility for the elderly plays an important role in balancing the rapid change of society.
Therefore, this study aims to evaluate the social benefits of implementing demand responsive transit service (DRTS). First, the study developed a mathematical model with objective of maximum social mobility and delivery times as decision variable to provide different patterns of service of DRT for the elderly among districts in Taipei City. Gini index is also used to evaluate the benefits in terms of the equity of resource allocation in public transportation after the implementation of the DRTS.
Three optimal models with objective function including social mobility, equity and operation cost are set to decide the best arrangement of the DRTS in each of district. The result of numerical case shows that the DRTS is better to be deployed in areas lack of public transportation such as Nangang district and Beitou district. Meantime, either objective in the numerical case proves that social mobility, equity and operation cost gets better performance after the differential arrangement of DRTS. It is also shown that range of service area, travel speed of vehicle and in-vehicle time are sensitive to the result. Results of this study provide a reference for the development of future transportation policy in the aging society.
