Once large scaled disaster hits a society, a large number of households and firms are simultaneously damaged. The traditional cost benefit analysis of disaster mitigation mainly focuses upon expected loss reduction, neglecting the catastrophe aspects of disaster risks. In this paper, it is claimed that the disaster risk management methods can be classified into risk control and financing methods. In order to cope with the catastrophic disaster risks, it is requested to build the integrated disaster management systems and extend the theoretical framework of cost-benefit analysis. In this paper, the authors present cost-benefit analysis methods of catastrophe risk mitigation and summarize research issues to be solved in future.

CVM has been applied to measure the value of non-market goods including natural environment. It has been known that measuring values by CVM tends to involve a number of biases. Consequently the NOAA's guidelines were proposed for measuring values without biases by CVM. However, the validity of the guidelines has not been clearly tested. In the present study, we replicated the CVM survey designed according to the guidelines by Kuriyama et al. for measuring values of natural environment in Yakushima-Island, and analyzed cognitive decision making processes based on a verbal-protocol method. The analysis indicated that it is not easy at all to measure value without any biases by CVM designed according to the NOAA's guidelines.

Although it has been questioned whether CVM can measure value assumed in micro-economic theory, CVM may be used for reflecting people's opinion or attitudes toward a public good in the policy with respect to the good. Therefore the policies determined based on CVM may be regarded as procedurally fair by people and may be more easily accepted by people due to the high procedural fairness. In order to test the hypotheses that policy based on CVM is perceived to be more procedurally fair and the perceived procedural fairness, in turn, increase the level of acceptance of the policy, a survey was designed and implemented. The data from the survey confirmed the hypotheses.

In this paper, the concept of ‘Social Capitalization of City’(SCC) is presented and the SCC Index (SCCI) is defined. The counter measures of SCCI are categorized into four groups: city planning legislation, building regulation, taxing and subsidizing institution, and environmental legislation. Finally, through the comparison with the English and German cities, the reasons why Japanese cities cannot be stocked and the counter measures to improve the SCCI are suggested.

This paper aims to develop a model of location preference of manufacturing industry companies in response to the change in level of service of travel time caused by highway construction. Two types of location choice model are proposed: One is a Logit type model directly incorporating a function decreased by distance. The other is a Dogit type model that represents the area-specific component determined by this distance function. The results show that the estimated parameters for both of two models are statistically significant, while hit ratios are not enough. They also suggest that, as the correlation coefficients between land price and the estimated area attractiveness are not insignificant, the area attractiveness have relations with the potential of the areas.

In the new environmental standard for road traffic noise, equivalent sound level was adopted instead of medium value. At the same time, the prediction model of road traffic noise was proposed by Acoustical Soc. of Japan. This model is utilized for the environmental assessment, and the application range is also wide. However, designers can not calculate easily the value of the road traffic noise using this model. Therefore, authors proposed the calculation method which satisfied two following requirements regardless of usual pavement, drainage pavement, though the application range is limited to the roadside noise as the automobile steadily runs.(1) Equivalent sound level can be easily calculated using mathematical expressions and figures.(2) Designers can easily decide noise reduction countermeasure of the object site.

We do not always well provided against disaster. This paper investigates how capital for restoration is procured after a society is damaged by an unexpected arrival of disaster whose damage scales are unknown. If a household's view along time horizons is finite, the financial initiatives arranged by the central government have non-neutral effects on life-long consumption of the household, and eventually have substantial impacts upon market dynamics. Besides the availability of capital in world financial markets, polar cases of which are represented by a closed-economy-model and an open-economy-model, plays decisive roles for recovery of the economy from disastrous destruction. In this paper, an overlappinggeneration-model is formulated to analyze effects on a restoration path driven by a financial procurements after disaster and a redistributive policy among generations.

This type of approach is especially useful for evaluating non-visible and constantly changing recovery state of commnities from a disaster. Based on the niche overlap index, an attempt has been made to derive theoretical implication of spatial-temporal statistics. It has been shown that community cohabitative communication level as measured by the proposed indicators showed some aspects of the inside of communities which can not be measured by the speed of recovery of buildings.

In Edo period, a lot of elements that characterized the city were gathered in the waterfront as a traffic terminal based on navigation systems, and that closely tied with residents. Waterfront and navigation systems still existed, but the role of them had to be changed because of railway systems and rapid industrialization. As a result, most characteristic facilities and amenity of the city were taken away from the waterfront However they were expected to sustain the management of the city in flood control and navigation systems.

We argue that context dependence (CD) affects the temporal change of SP data. To reflect this, we propose a new mode choice (r-RP/SP) model based on relative utility function, which consists of the term of alternative similarity and the term of other context-dependent factors like previous choice results. Throughout an empirical analysis, it is confirmed that, (1) the way of using relative utility to incorporate the influence of the CD is effective, (2) the parameters of relative importance (RI) are variant temporally and affected by the CD, (3) as the number of explanatory variables increases, the parameters of RI fluctuate largely among individuals and over time.

This study aims to verify several non-compensatory decision strategies, such as conjunctive rule or disjunctive rule in travel mode choice. Decision strategies are formulated as probabilistic models. The attributes specifying the selection of alternatives are defined as latent variables through structural equation modeling. The empirical analysis focuses on the choice of public transportation for private trips to the surrounding inner-city areas in Tokyo. Finally, we concluded that non-compensatory decision rules, particularly the conjunctive strategy, were found to be more prominent compared with the compensatory rules in the process of alternative cut-off.

In this paper, time choice models to and from work are developed using panel data collected during a three-year period after the introduction of flex-time system in a company. Interesting facts revealed include:(1) the habitual effect of to work departure times continues after the new system is implemented, but decreases over time, (2) household structure does not have a great effect on to and from work departure times, and (3) interdependence between times to and from work are significant. In the light of these conditions, it is believed that to and from work departure times are decided simultaneously, hence a simultaneous choice model is formulated and estimated based on the same data. The interdependence between these two times is significantly confirmed in the model.

Existing activity-based models typically assume an individual decision-making process. In household decision-making, however, interaction exists among household members and their activities during the allocation of the members' limited time. This paper, therefore, attempts to develop a new household time allocation model by combining group decision-making theory and time allocation theory. To do this, this paper proposes defining household utility function in the form of multi-linear utility function to represent the interactions among household members and the interactions among their activities. The effectiveness of the developed model is confirmed using activity-travel diary data. Finally, several future research issues are also mentioned.

User equilibrium assignment models considering realistic intersection delays, signal setting control and soon, generally have no analytical guarantees on stability and uniqueness solution. However, these models should not be denied immediately. That is, these models will give useful results under the condition that the solutions have adequate validity to use by verifying the validity of solutions. This study verified the validity of user equilibrium assignment model introduced signal control that authors developed and clarified that the model do not have unique solution but have solutions with adequate validity.

In this paper, we propose using a disaggregative behavioral model in choice of bicycle-parking place, and using the Alternative Hieratical Process (AHP) as the method for grasping consciousnesses of illegality.
First, we did a cluster analysis using the score of AHP, and carried out segmentation of the sample. As a result, we made two segments with completely different consciousness about illegal parking. Moreover, we observed that the utility functions of these two segments, considered from the disaggregative behavioral model built for every segment, differ clearly.
Finally, We verified the validity of using the model built by sensitivity analysis.

One of the solutions for energy resources and environmental problems is to promote bicycle transportation. In this study, we investigate the modal shift in the transition period from bicycle users to automobile users. As a result, there were four factors. Physical conditions refer to reasons that influence bicycle usage. Financial Conditions refer to how much one can spend on purchasing a car and on its maintenance. Bicycle Habit is experience of bicycle use in the past Bicycle Favoritism is the preference of bicycle as a transportation mode. Bicycle transportation planning must be based on the policy to enhance these factors.

The objective of the study is to analyze information acquisition and activity-travel patterns in traveling by walk and public transport through an experiment of implementing an activity program. It was examined when, where and how respondents used information by PHS spatio-temporal data and information diary survey. The process of activity scheduling and rescheduling, and information acquisition behavior were described in detail. The frequency of referencing a map was high for searching current location and travel route on road and in buildings. Pedestrian navigation system guiding a route of minimum distance in traveling multiple destinations could decrease travel distances.
