Abstract
This paper deals with bus use promotion measures for commuting travel which is a low-cost solution to the traffic congestion during peak hours. It first categorizes factors determining mode-captive situation into 4 groups, namely subjective, residential area, work place and time factors, based on a questionnaire survey conducted in Naha metropolitan area in Okinawa Prefecture. Then it estimates the effects of park-and-bus-ride measures, which reduce mode-captive factors connected with residential areas, to divert commuting travel from car use to bus use. Captive-conscious modalchoice models are proposed and applied to Naha metropolitan area with success.
