Abstract
In general, traffic congestion in local area is observed only at peak hour. Therefore, it is significant to estimate the effects of transport policy for temporal dispersion of traffic at peak hour in local area. The present paper is aimed at identification of factor for decision-making of departure time on commuting by car in local area. In the present study, commuting time of car user in local area is analized with the database of the person trip survey in the Tokushima city area. The distribution of commuting time for commuter with the fixed starting time for work and commuter of the flextime system is analized. In particular, the commuting time decision model of car user in the local area is described with survival time analysis. As the result, it is not easy to acquire sufficient compatibility in the model with specific probability distribution. On the other hand, it is suggested that the semi-nonparametric model is suitable for description of commuting time of car user in local area.
