Abstract
Rural and mountainous areas in Japan (covering 70% of the total area and 13% of the population) are characterized by poorer level of public transit services and higher car ownership than in urbanized areas. Most of the elderly usually depend on “deliver/pick-up” by other household members when going=out. This paper therefore aims to develop a new household time allocation model, which can represent heterogeneous intra-household interaction based on iso-elasticity social welfare function. Throughout an empirical analysis using activity dairy data collected from a rural and mountainous area in Shimane prefecture, the effectiveness of the proposed model was confirmed. Furthermore, model applicability to evaluate the influence of the elderly transportation policies was examined based on simulation analysis.
