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.

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.

The main purpose of this paper is to measure and compare the network performance of selected thirteen major airports in Japan. After classifying network connectivity into four -direct, indirect, onward and ub, this paper develops a model (NetScan model), taking into account transfer time and detour time. By quantifying an indirect connection and scaling it into a theoretical direct connection, the network diversity behind direct connections and the competitive position of Japanese major airports are identified. The results reveal that Narita has the remarkable network performance behind its direct onnections, especially to North America.

The Tokyo Metropolitan Area has been developing for a long time since early last century. Despite of this, the population census in 2000 reported decrease of daytime population in the Tokyo Special Ward center of Tokyo Metropolitan Area). Using data from population census in 2005, this article estimates the current trend of daytime population in the Tokyo Special Ward.

CO2 emission from transportation sector in Japan has been reducing due to increasing fuel price, economic recession and CO2 mitigation policy mix, which includes fuel economy regulation and tax exemption for purchasing better fuel economy vehicles. Japanese government makes further CO2 reduction polices with tightening fuel economy regulation, because Japanese government intends to certainly reduce CO2 emission from transportation sector. Existing researches, however, show that policy mix based on fuel economy regulation and tax exemption for buying new fuel-economy-improving car losses social welfare. Fuel economy trading has been gotten a lot of attention as an alternative policy for fuel economy regulation. This study evaluates introduction of fuel economy trading policy, a kind of tradable permit policy in transportation sector, to Japan. I use computational partial equilibrium model to simulate and evaluate effects of the policy. As a result, fuel economy trading policy doesn’t undermine social welfare than fuel economy regulation, but reduction of CO2 emission by the policy is less than by the regulation.

Considering induced/developed traffic means that it relaxes the assumption in the evaluation/forecast of the conventional transportation plan, and changing assumption surely ends up with the changes in the results. In this paper, we simulated the change of the benefit by the further development of road networks in the Tokyo Metropolitan area with the different assumptions. As result, we found that including induced/developed traffic does not change user benefit a lot, while CO2 emission are subject to much more change compared to the conventional way.

Dramatic changes in international trades were analyzed to identify recent development of Asian manufacturing network and interdependency among Asian countries in this regard. Current situation of Asian transport network was also reviewed, focusing on road and railway sectors, in terms of both supply side and demand side for discussing possible future needs to further invest in soft infrastructures and hard infrastructures in the context of creating trans-Asian seamless transport network. Finally possible actions to be taken by parties concern were recommended for developing Asian common transport policy.

Information on the trend of ship dimensions at intra-East Asia sea route is very little. However, an increasing percentage of Japan's foreign trade is with East Asia. Therefore, in this report, the trend of full cellar container ship dimensions at intra-East Asia sea route was quantitatively analyzed.
Deploying new, large container ships into trunk line has the cascading effect, which leads to redeploying smaller existing ship to other sea routes. The impact of this cascading effect to the enlarging the size of container ship at intra-East Asia sea route was also analyzed.

An increase of automobiles in Japan slowed down year by year recently. The increasing rate of last year (2006) was only
0.2%. Demands for new automobiles of the first half of this fiscal year (from March to September of 2007) decreased down about 91% compared with the same term of last year. This report reviews the process of Japan’s motorization and saturated status of Metropolitan Area such as Tokyo Metropolitan Area, Osaka Metropolitan Area, etc and tries the future prospect of automobile in Japan.

Sightseeing Railway, mainly cable car still plays a significant role as access mode to pleasure spot. However owing to motorization and diversification of leisure, their financial environment is extremely severe．And some lines were forced to a stop．This paper reports their peculiarity of operation and correlation of passenger demand and customer traffic．I suggest a wish for maintain or activation of Sightseeing Railway．
