Environmental problems are becoming worse, and increase in the movement of people is also causing concerns. However, the change of transport activities is slow, the unnecessary use of cars has not adequately decreased and the optimum conditions of transport activities are not satisfied from a viewpoint of mobility and accessibility. An intermodal transport policy for highway buses and city railroads is necessary to effectively use the social infrastructures in neighboring cities where various transportation options exist. We must change from cars to use of public transit. However, the convenience of transfer to highway buses and city railroads can not be clearly incorporated. In this study, to plan and perform an intermodal transport policy in regional public transportation planning, we quantitatively verified the intermodal transport policy for the construction of a transportation network system connecting the highway and the city railroads in neighboring cities at the planning stage. Specifically, we investigated the various factors affecting the transport activities of the inhabitants of Kameoka in Kyoto Prefecture, Japan along the Kyoto Jyukan Highway. A questionnaire based on this area was used to analyze the transport activities of the inhabitants and their consciousness about the intermodal transport policy. We constructed a traffic choice model based on an intermodal transport policy that connects highway buses and city railroads (Park and Bus Rail Ride) to the present transport system and estimated the shift in transport activities with a new traffic mode in this area. In addition, we also conducted a resident questionnaire on issues such as parking, railroads, and buses to clarify the incentives used in the selection of mode of transportation. The results of this evaluation confirm the importance of intermodal frames and help to clarify the impact of the traffic behavior of people.JEL Classification: R41, R48, L91, C91
