This study analyzes the variation of the Value of Travel Time Saving (VTTS) over travel time. First, we formulate a time allocation model with the discrete choice theory. Next, we derive the VTTS from an approximated indirect utility function. After a discussion on the properties of the variation of the VTTS over travel time, we analyze the VTTS with the empirical data of modal choice of inter－urban leisure travel of Japan. The empirical analysis shows the VTTS decreases as the travel time increases. Finally we discuss the reasons for the results of the empirical analysis

A recent economic growth enabled Asian container hubs to undertake dramatic innovation of terminal management and operations which resulted in rapid increase in the container throughput. On the other hand, former container hubs of Japan such as Kobe have stagnated in the last decade because of the high port charges and time consuming port procedures.

This study describes recent policy development undertaken by the Japanese government to improve port competitiveness with launching new soft loan and taxation measures for assisting private terminal operators. This study also examines the policy by evaluating its efficiency and effectiveness.

The flexible operation of terminal air traffic was analyzed to enhance runway capacity at HANEDA airport. The airport capacity determined by landing aircrafts was estimated using a simple microscopic air traffic simulation system developed in the study. Using this simulation system, it is possible to reproduce the aircraft movements considering the size-depended characteristics of each aircraft such as separation minima, runway occupancy time and noise level. The results showed the significant increase of airport capacity and the consequent changes of user's benefit and noise pollution by proposed aircraft control patterns.

The object of this report is to introduce the basic concept of "The Manual for the Comprehensive Evaluation Method of Railway Projects in Japan" and the result of discussions about 1) Application of the comprehensive evaluation method into railway projects evaluation, 2) Establishment of advance and post evaluation methods based on PDCA (Plan-Do-Check-Action) cycle, 3) Revision of a cost-benefit analysis at the Committee meeting for a manual creation.
