Stated preference survey on shifting commuting time by incentive measures is conducted to railway commuters in Tokyo metropolitan area. ‘Points for train ride’, ‘discount of station access cost’, ‘lounge service at the terminal station’ and ‘train congestion reducing’ are set as incentives for commuters’ time shifting in the survey. As a result of that, authors find that 1) the condition of incentives (e.g. amount of point) is independent from the amount of time shift, 2) the intention to shifting time is not linearly related to the amount of time shift, and seat availability and points for train ride have potential to change departure time.

Currently, the local government usually plans the public transportation service in rural areas. It is critical to show the service level standard of public transportation service in order to hold the fairness of the plan. This study discusses the meaning of the service level standard which can be found in Local Transport Plan in England. Then the methods to derive the service level standard are developed by using mathematical models. Specifically, the methods for classification of the area and assignment of the service level are discussed. Finally, the case studies are performed to demonstrate the usefulness of the standard.

This paper discusses the crucial issues considering the desirable demand balance among three airports locating in Metropolitan Osaka, i.e. Kansai, Osaka, and Kobe Airports; the issues are runway capacity constraints at Kobe Airport, and unfavorable location of Kansai Airports in terms of accessibility. We apply the bi-level type network equilibrium model to domestic transport markets from/to Metropolitan Osaka. We have a few suggestions from the computation. One is that in terms of total passenger's flow, the discount of access fee to Kansai is limited, while relaxation of capacity constraints at Kobe is very effective.

Recently the promotion of tourism is active in Japan. A time-series analysis based on statistical data is very important in order to suggest efficient tourism policies. This study focuses on the number of tourists in approximately 230 sightseeing areas and analyzes the time-series data from 1985 to 2004. In the study, the relation between the type of sightseeing area and the trend of tourism is illustrated.

The number of passengers is falling in most of airports operated by local government. This study shows how to operate and manage these airports by making a trial calculation of revenue and expenditure, examining beneficiary payment principle, and considering possible designated manager system. The study concludes with some implications for policy makers.

This paper examines ways to assess impacts of commuting by mass transportation both on physical and psychological health of workers. Two set of indicators are proposed, both of which are calculated by applying heart rate variability analysis to examine the condition of autonomous nervous system of commuters. One of the indicators assesses the magnitude of stress in a particular time or running section, while another indicator assesses the volume of overall stress accumulated during commuting. A comparative study of commuting stress for Express train and Local train running on one of major lines in the Tokyo metropolitan area is to be conducted.
