This study aims to clarify proper information provision methods for residents with different decision-making process in a river disaster situation. A protocol survey was conducted on the decision-making of 22 subjects (7036 actions) in terms of behavior and evacuation using images of flooding. The analysis results showed that the thought patterns of the subjects could be divided into three types : recollectors, envisioners, and composites. It was investigated effective methods of information (not only the evacuation order, inundation and river flooding conditions, but evacuation sites and routes, relating to their families and house) provision that are based on thought patterns. Prior awareness of the river disaster risk perception suggested to influence thought patterns. So it was investigated land transaction prices of 812 sites using the hedonic approach to analyze risk perception. The people's awareness of river disaster risk perception was quantified and examined. Awareness of disaster-related factors, such as magnitude of past, present and future flooding, time since the previous flood, and distance from flood locations were characterized.

About the transportation phenomenon in case of an earthquake disaster, it has been solved in detail by various researches after the Kobe earthquake. However, it is not in the situation that analysis does not progress what kind of influence is brought about by the people who are difficult to escape from the disaster area to their home, since it did not become a big problem in the Kobe earthquake. In this research, influence of these people to the transportation situation after an earthquake disaster is clarified, and after some countermeasures for corresponding to it are shown, the effects of these countermeasures are compared by “an urban activity simulation system in case of an earthquake disaster”. The countermeasures considered here are relating with the distribution method of relief goods, method for going back home and reinforcement of a stockpile, and comparing the effect shows the direction of the transportation countermeasures in consideration of the correspondence to earthquake disasters.

This paper aims to measure a historical impression of streets on the composition of roadside elements. “Grain Theory” was introduced that intends to analyze the character of streets or districts by the density of town element such as shops and housings. The results of an experiment on the historical impression were analyzed by 11 sorts of grains. As a result, some important facts were gained : to get an historical image, over 20-30% of authentic grains were needed, and disturbing grains should be under 10-20% of historical grains. And a formula was shown that predicts the historical impression of a street on the composition of grains. Some measures to reinforce the historical street image were taken from it.

Improvement of Quality of Transport (QoT) is urgently required under increasing need for mobility. But planning methods based on existing LOS concept are inadequate to reflect various needs of mobility-handicapped and non-handicapped people. In this paper, assessment method of QoT in congested pedestrian space is developed and is applied to a collaborative design by engineers and citizens. In a case study conducted in pedestrian-space plan, enhancement of QoT by setting moving-walk, resting space, information office etc. is quantified by the following four elements, mobility, amenity, information, and assistance (MAIA). Based on the quantification of MAIA-weights and QoT of design options, we examined an effective procedure for screening of alternatives and consensus building.

This paper's goal is to develop the international trade model with the equilibrium constraints on maritime transport market in order to estimate the short-term economic impact of transition of port management policy. Especially, the present model explicitly concerns the effect of global alliances. First, we assume the oligopoly market, in which global carriers compete with vessel frequency in each OD market as well as the stochastic allocation on the shippers' route choice behavior. Thirdly, we bind these two sub-models to full model, which obtains the Nash equilibrium between global alliances. We apply this model to the actual international maritime transport market in 2000, and evaluate some scenarios of discounting the port charges.

This paper discusses on the design works of Masayoshi Kabashima (1878-1949), one of the famous bridge engineers in the modern period of Japan, for the pourpose of showing characteristics of his design thinking and examines where we should place the significance of his design methodology in the modern history of Japanese bridge design. The most important works of Kabashima is urban bridges design in Tokyo city, Kaji-bashi bridge, Gohuku-bashi bridge etc. In these works Kabashima showed the design method to create bridge appearances or landscape based on the understanding of the placeness which is reached by reading the urban context. The usual design method of urban bridges in Meiji era was to put some ornaments on bridge structures like plate girders or trusses, so his methodology based on the values of urban spaces and landscapes not on only ornaments can be placed as an epoch in the modern history of Japanese bridge design.

A multi-modal traffic assignment model is proposed in this study. Auto, bus and railway transport system, and their interactions are simultaneously expressed in the model. A model that determines optimal amount of antifreezing admixture dispersion is also proposed. This problem is formulated as Network Design Problem (NDP) because passengers would change both transport modes and routes depending on the level of service for road network determined by the amount of antifreezing admixture dispersed in winter. Responses from passengers to the amount of antifreezing admixture dispersed are expressed by the multi-modal traffic assignment model. Lastly, calculation results obtained by using test network are presented.

We examined the use of rumble strips on a national highway as a measure against head-on collisions. Studies were conducted on the necessary construction machinery, construction methods, and the effects of installation on a road in service. In addition, we examined the use of rumble strips as a measure against run-off-the-road accidents. The strips were found to be less costly, and easier to install and maintain than traditional measures against head-on collisions. They were found to be safer for motorcycles than are center poles and chatter bars, and effective in reducing head-on collisions.
