    Due to the recent progress of technology in information and communication systems, the necessity is increasing to make some frameworks to analyze traffic behavior including the influence of traffic information. In this paper, driver's responses to uncertain traffic situations and traffic information are observed by making several traffic activity models. For these analyses, two types of model using generalized means formula are proposed. One is a regression model to estimate travel time on next trip by travel times based on past experiences and the other one is a disaggregate logit model which is considered substitution of plural factors of utility function. These models are applied to SP data and the possibility of application is considered.

    A critical question in water resources developments is how to allocate the joint costs amongst multiple uses. If each use has a different incentive in the timing and ordering of participation, the cost allocation method to be applied is required to appropriately reflect such bargaining factors. This paper approaches this type of cost allocation problem by use of game theory. Theoretical study is carried out to examine the Weighted Shapley Value as a promising method. Another fair allocation schemes called the Priority-Ordering Nucleolus and Expected Priority Ordering Nucleolus are also developed by modifing the definition of Nucleolus. Theoretical and numerical examinations are made to examine applicabilities and limits of the proposed methods.

    A connectivity measure is proposed for evaluating the reliability of a deteriorated transport network. The connectivity between an origin and destination pair is defined as the probability of whether the ratio of the OD travel distance in a degraded network to that in the normal network is less than a given criterion. Approximation methods for calculating the connectivity measure and the cumulative distribution function of the travel distance of an OD pair are developed which considers a part of probable state vectors. Through numerical examples, proposed connectivity measure and its calculation method are verified.

    Recently, the production of reasonable landscape design method is one of the most principal problems on river. The authors had presented that fractal objects have been found out in the location and size of elements in landscape, such as stones or trees, and shape of waterfront.
    In this paper, the authors have examined the applicability of landscape design utilizing fractal of landscape elements. Consequently, the reasonable plane models of location and size on stones or trees, and shape of waterfront are produced by this supporting method. And, it is shown that river landscape design in consider of fractal can be one of objective design methods to reflect the naturalness of each river.

    In recent years, ports have been increasingly opened to general citizens. As a result, it has become possible for citizens to enjoy viewing a variety of scenic elements there. In such locations, importance should be attached to the views of port facilities, which constitute scenic elements characteristic of harbors.
    The results of this research, based on an hearing survey taken at the site (harbors), is designed to shed light on citizens' evaluation of the scenery of port and harbor facilities, on desirable combinations of these facilities with other existent scenic elements, and on properties of scenery that compose such desirable combinations.

    The purpose of this paper is twofold. Firstly, we constructed the model to discuss the two-regional equilibrium model for evaluate to the welfare losses of transportation infrastructure improvement projects. Secondly, we utilized the ADD measure and its second order approximation to analyse the approximity of the equivalent variation within the context of two-regional general equilibrium model. In particular, we clarified the limit of overestimation or underestimation of ADD second order approximation in regard to sensitivity analysis of parameters of cost function. Concluding, we could see the accuracy and availability of the ADD measure and its second order approximation.

    This paper proposes a model for choosing a departure time by air travel passengers for the purpose of business. It is the first model for forecasting the temporal demand of transportation on a long distance travel. The passengers, ordinary have their work start time and end time. The passengers make a schedule of their travel in the time. The model is formed two models that choosing a flight on the day of the business and choosing a flight on the day before the business. The model is based on an assumption that passengers choose their departure times to minimized the sum of disutilities derived from their life pattern. The model reappears the behavier of the air travel passenger going to Haneda form Thitose.

    This research proposes the formulation and a solution algorithm for the reactive dynamic user optimal assignment with physical queues. Given a many-to-many OD, under the reactive assignment, users are assumed to choose their shortest routes to their destinations based upon current instantaneous travel time, but not based on their actual travel time (or cost). First, the flow conservation and the First-In-First-Out discipline are established as constraints of the assignment. Second, the optimality condition of the reactive assignment is formulated. Third, based on the shockwave theory, the back-up phenomena of physical queues are included in the model. Finally, a solution algorithm is proposed and demonstrate an example of the assignment using a network with parallel arterial and freeway.
