The sound development of public transit is in line with not only the basic concepts of green transportation but also the objectives of sustainable transportation. In recent years, the Taiwanese government has been aggressively investing in the development of public transit systems.
Currently in Taiwan, there are about 1,000 operating conventional bus routes, 93,000 bus stops and 8,000 operating frequencies of the conventional buses. With such great amount of conventional bus services, it has become impossible to analyze their service gaps by mean of either manual method or simple information management method. This study integrated such datasets as residential addresses, socioeconomic data, location of public transit stops and frequency information to establish an index capable of assessing the spatial-temporal transit service gap. Furthermore, this study also utilized the spatial analysis functions associated with geographic information systems to develop a spatial decision support system. By means of the simple user interface developed for the system, future users of the system would be able to quickly analyze if there is a temporal public transit service gap in certain areas that causes inconvenience to the public transit users of those areas. In addition, when compared to the traditional spatial-base analysis, this developed index is capable of integrating both temporal and spatial elements making it even more appropriate to distinguish the difference in public transit service among analyzed areas. For those authorities that are developing seamless public transportation service, the results of this study would provide them with a useful reference and a basis upon which to assess their studies.
