The objective of this paper is to develop a model system of departure time choice for commuter trips in Tokyo metropolitan area, for forecasting urban railway passenger travel demand. There are few comprehensive departure time choice model systems in consideration of urban railway policies for practitioners. This model system is composed of an integrated combination of departure choice model, time of day choice set generation model and link cost model. By using this model system, we can measure the effectiveness of demand management policies such as flexible work time system, congestion charging. Furthermore, the increase in the number of train operation to reduce peak period congestion may cause decrease of user's utility can be pointed out.

This paper discusses the "100 yen bus" which has been introduced by bus companies since the late 90s. Based on our survey research, lowering bus fares tends to decrease the revenue of bus companies on balance and it does not lead to the revitalization of city centers on holidays. However, the number of elderly passengers and passengers on week days increases in many cases, in particular, in regional hub cities. Under a well planned urban transportation policy including subsidies, the "100 yen bus" or elastic bus fare system has the possibility of activating those cities as well as bus companies.

Real options, a development of financial economics, is a workhorse for dealing with uncertainty. This method, however, has seldom been applied to public infrastructure investment. We present a method of real options analysis that is easily used in the on-site planning process for large scale projects. We also present the rational criteria for determining the maximum amount of cost increase due to conducting the construction process in phases, and the maximum amount of anticipatory investment.

The Customer Satisfaction Evaluation Method (CS) is applied as the tool for the performance management of airports. On the other hand research on CS as an Evaluation Measurement Tool (EMT) for airport planning is inadequate. This paper discusses on the usefulness of applying CS as EMT on the quality of airport service by using the case study survey of Fukuoka airport. As the result of this study the efficiency of each service area connecting to the whole airport service and the structure of CS on the airport service are clarified.

This study analyzed competition promotion policy regarding shipping conferences in the U.S., EU and Japan, and subsequent changes in corporate behaviors. It also analyzed competitive nature of liner shipping industry by estimating Panzar-Rosse H statistic based on panel data of three major Japanese shipping companies between 1986 and 2002. The block exemption for price fixing and capacity regulation by shipping conferences has been granted. However, since early 1980s, the competition promotion policy has enabled each shipping company to set its own price freely, affecting price cartel significantly and leading to the decreased market power in shipping conferences. On the other hand, new cooperative firm relation has been formed between shipping conference members and independent operators. Panzar-Rosse H statistic indicates that the three major Japanese liner carriers do not behave as forming perfect collusion. This result is consistent with monopolistic competition. It seems that competition has been intensified following the introduction of competition promotion policy.
