EVALUATION OF NETWORK STRUCTURE WITH A NON-UTILITY BASED TIME ALLOCATION MODEL

Abstract

Understanding appropriate characteristics of network structures is necessary to construct efficient transport systems. This research proposes a methodology evaluating transport network structures with considering how large people's activity area is expanded by transport system. People's behaviour in a network is described with a non-utility based time allocation model which is newly developed in this study. An index referred to as “visiting ratio” is proposed in order to evaluate the area where people intend to visit. The proposed method shows that network structures where travel times to the different destinations are distributed equally are more appropriate in terms of the visiting ratio. Also, a phenomenon that constructing a new link may result in lower function and an advantage of scale-free networks are also shown.
