Exploring Diversity of Public Transport Usage with Smart Card Data and Its Associations with Accessibility and Land Use Patterns

抄録

With the rapid development of information and communication technologies in recent years, developing better ways to utilize the large amount of data has become an important research agenda in urban and transportation planning. In this study, we (1) develop a method for estimating the role of each station/bus stop in a city by quantifying the regularity of public transport usage at the station/bus stop level using smart card data, (2) calculate the diversity index using the regularity information, which is defined as “the degree to which there is a mixture of people who use public transportation at various frequencies”, and (3) analyze the relationship between the diversity index with land use patterns and accessibility of stations/bus stops. Our empirical analysis confirms that improved accessibility encourages diversified use of public transport systems, that may contribute to the stabilization of travel demand and hence the stabilization of public transport services.
