    Effectiveness as well as financial accountability of investments of infrastructure and disaster prevention is guaranteed by economic growth in future. On the other hand, non-uniform distribution of their benefits brings up an issue of cost allocation. Areas of infrastructure planning and disaster management have shown interests in issues of long-term impacts and distribution. Taking recent vigorous discussions on “growth and inequality”, it is meaningful to review past questions and insights derived from them. This draft puts arguments about impacts that disasters and infrastructure investments give on economic growth and inequality into shape, and proposes a new perspective that the area of infrastructure planning could take.

    Changes of a physical property in a local asset such as a park and a shopping street may result in changes in the number or variety of participants in festivals and rituals that are held there. Changes of participants may also lead to new collaboration in the activity, through which interactions in daily life would also expand. This expansion of social networks can be regarded as a value that the physical property brings.
    This article, first, demonstrates that existing social network formation models are insufficient for the evaluation of the above function of local assets, and then the article presents our proposed method that overcomes the problems. The method applies a multilayer network formation model which expresses interaction in collaborative activity and in daily life with different network layers. The method could evaluate the function of the collaborative activity itself and the physical property in local assets through measuring the effect of new collaboration in the activity on the network formation in daily life. Through the above process, this article seeks to indicate a direction of the development of a methodology for the evaluation of the function of local assets on social network formation.

    Urbanization and climate change, which are greatly interacted, influence not only urban economic activities but also more multi-dimensional happiness. In order to enhance acceptability of climate policies, it is thus necessary to globally evaluate their impacts on happiness, taking account of the influences of urbanization and climate change. However, the impacts of urbanization and climate change on happiness have not been examined comprehensively, considering both influences of the urban environment and the natural environment. This study aims to clarify the capabilities and limitations of internationally-developed happiness indicators for the application to the evaluation for influences from urbanization and climate change. First, a literature review on happiness evaluation is conducted to classify the evaluation methodology. Then, another literature review on the relationship between urbanization, climate change and happiness is made to identify key factors of their influential mechanisms. Finally, the characteristics of existing happiness indicators developed by international organizations are sort out to clarify their capabilities and limitations for the application to the evaluation.

    The evacuation to an offshore area is recognized as a method to prevent risks to fishing boats under tsunami attack. However, when the boats encounter a tsunami in areas with insufficient water depth, evacuation offshore is a dangerous method. To evacuate to the land from the sea, one must decide the fishing port and shelter for fast evacuation.
    Through evacuation drills at Minamiise town, Mie, Japan, we attempted to understand evacuation time and the means of getting tsunami warnings at sea. The results of our survey were announced at some workshops, and a questionnaire for fisherman was used to discuss ways to evacuate their fishing grounds to tsunami shelters or offshore. As the result of such activities, a tsunami evacuation map for use at sea can be prepared.

    It is pointed out that those who have a high recognition of disaster risk does not always take precautionary actions against natural disasters. This is called disaster risk perception paradox. It implies that improvement of disaster-risk perception does not always lead to individual preparedness or response against natural disasters. A lot of past researches focused on individual implementation or motive of actions against natural disasters to promote them; however, they are different in the promoting or disturbing factors to explain them. Against this background, this paper verifies global and local characteristics of individual mitigation actions through the same questionnaire surveys over 6 regions to obtain an unified view of the resolution of risk perception paradox. Consequently, for the promotion of preparing an emergency bag, it concludes that it is commonly effective to improve a perception of the coping appraisal in response efficacy and cost rather than the threat appraisal about natural disaster.

    This study estimated the number of seriously injured people and spatial distribution and examined the transportation strategies of seriously injured helicopter in the isolatability villages as a study of Shikoku area which expected to suffer severe damages in the Nankai Through massive earthquake.
    As a result, seriously injured people in Shikoku were scattered widely when the Nankai Through massive earthquake occurred. In addition, it was clear the strategies of transporting seriously injured people on villages level requires an enormous number of days. It was suggested that one transportation base is provided in the elementary school district or the junior high school district and serious injured people are transported by combining the large helicopters and the small helicopters from there, so that it can be transported more quickly and efficiently.

    This study investigates the effectiveness of infographics in public notice documents through eye tracker experiments. Pupil diameter is considered to assists in determining a participant's attention to a specific object. Typically, pupils unconsciously expand in response to stimulation due to participants' interest and excitement. Through measuring the pupil diameter of participants under the condition reading newsletters with and without infographics, it is found larger pupil diameters occur when infographics were applied. Statistical t-tests confirmed that the difference between the condition with and without infographics was significant. Therefore, it can be implied that increasing interesting contents through using infographics in newsletter can attract readers.

    The collaboration between residents, local government and professionals is said to be an important issue for revitalization of community. Although, it is inevitable for the projects of revitalization of community to adopt a collaborative approach with getting local government and coordination experts' support, confusions in partnership sometimes occur due to the lack of continuous or effective professional coordination. The aim of this study is to clarify rolls of professional coordinator in forming collaborative activity using a method of profile of practitioners proposed by John Forester, by analyzing profiles of five practitioners whose position of collaboration or professional expertise are different. As a result, All practitioners had the some actions for the objectives of collaborative approach listed by the authors, but there action for each is not the same style and depends on their role.

    Computable urban economic models (CUEMs) have been developed as strong tools for analyzing the effects of urban policies such as transport investment projects. CUEM describes the interaction between land use market and transport market consistent with microeconomic theory. This paper develops a new framework of CUEM considering agglomeration externality and floor market, which are typical aspects of urban area. We furthermore analyze the characteristics of model behavior comparing with the existing CUEMs which consider either of the above two urban aspects.

    Mobile phone location data enable us to overview the damage of disaster on human behavior from new viewpoints. In this research, we proposed the new viewpoints and methodology for observing the damage and recovery process on human mobility patterns from mobile phone location data. The methodology were applied to the “congestion statistics ®” data for analyzing the Kumamoto Earthquake 2016. The results indicate that the proposed methodology can estimate the rough number of evacuees. Moreover this methodology enable us to obtain additional information (ex. conditions of working or moving behavior) in real time. These information help us to decide the disaster response and relief supply strategies.

    The development, measure, location guidance and any of other projects that the local government is working on for achieving a certain purpose has possibility to show negative influences when we look from the other point of view. However, if each department would be able to assume these influences in multiple perspectives easily, it become a motivation to bring other departments, which be affected by projects, to the table for examine the countermeasure together. As a result, it would be expected to ensured consistency across the different departments.
    In this paper, we studied the structure for evaluating the influences of the projects with a various perspectives, and ran it practically in the actual city. From the result of questionnaire survey for practitioners in each department, we figured that they already recognized the importance of evaluation from the different perspectives. And also, by the responses from the each department towards evaluation index, we indicated how important to build the structure of evaluation that involved other departments.

    Water is essential for human lives and social activities. By the increase of urban population, the amount of water particularly used in the urban cities will also increase accordingly. In this prediction, it is fared that water stress will also be higher. In previous study, they showed the water stress map based on the county size or river basin size. However, no studies focus on the water stress based on city level. This study proposes a new parameter “river basin urban population density” that can consider the river basin area where a city included in as a hinterland. By using this parameter, water stress in cities is evaluated in Israel. The results show that the water stress in the cities increases about 1.4-5.6 times compared with the water stress in Israel.

    As large-scale floods caused by climate change have occurred recently in areas throughout Japan, there is an urgent need for the formulation and implementation of adaptation measures. Since 2013 we have been studying large-scale flood countermeasures based on workshops involving local cooperation in Kagawa Prefecture's Chusan area (the Doki River basin). When large-scale flood damage occurs, a response as a unified community is required from the viewpoint of regional continuity, and consideration of a DCP (District Continuity Plan) is necessary to maintain regional functions. The government is collaborating with residents under the aim of formulating a DCP for the Doki River ahead of other areas in Japan.
    In this research, we organized the examination processes carried out in the Doki River up until now and in addition to extracting their features, examined the possibility of improving the community's disaster preparedness through implementation of the action plan that had been created.

    This paper develops a short-run economic damage assessment model. The model contains two sub models. One is the conventional traffic assignment model, which calculates traveling time under the damaged transportation infrastructure. The other is the economic damage assessment model, which determines the decrease in production level in the short run. This model can analyze the factors that affect economic damage the most in each industry in each zone. As a case study, we applied this model to the Chukyo metropolitan area to evaluate the short-run economic damage of the Nankai Trough Earthquake. In addition, we also analized the effects of recovery plans for transport facilities and the influences on the time shift of the economic damage by considering inventories of intermediate goods. As a result, it is assumed that the comprehensive policy, considering the recovery timing, the damage factor and the regional characteristics, should be planned.

    Urban transport projects generate not only direct effects such as transport required time reducing benefits but also indirect effects such as effects of location change or creation of jobs, expansion of firm products and household incomes. The CUE (Computable Urban Economic) model has been developed to evaluate influences of location change. However the CUE model has a issue that can not evaluate the effects of creation of jobs or expansion of firm products and household incomes, because, in the CUE model, only land markets are taken into consideration without considering other goods or factors markets. In this paper, we built the integrating model of CGE and CUE modelling and applied to evaluate benefits of the Ring Road Projects in Nagoya. We measured the incidence benefits of each zone included the effects that is generated by job creation or expansion of firms products and household incomes.

    Last decade, there are many studies about the productivity related to the transportation investment in not only Japan but also several foreign countries. However, there is no common result on this issue because of differences of the measuring the service level of the transportation network and the productivity and of the using the data set among the prior studies. Thus, the purpose of this study is the establishment of the standard method to measure the productivity change from transport investment. Firstly, this study classifies previous studies from 6 points of view. These contents the analytical method, functional type of the production function, explained variable in the production function, service level of the transporta-tion network, estimation method, and aggregation level. Then this study measures the productivity of transport investments in Japan as an empirical study. From these analysis, differences in the results are made by the difference of the measuring the total factor productivity despite the same data set. So, it is important to establish the standard method to measure the service level of the transportation investment and the productivity.

    Cascading failure is a phenomenon where a local failure triggers a global propagation of failures, leading to serious damage to the whole system. In mutual interdependent infrastructures, failures in one system can spread out across multiple systems because of existence of interdependency. This study focuses on the interdependency between power grid and communication system and proposes a simulation model for cascading failure in interdependent networks which considers both failures by overloading and failures by dependency. In the numerical analysis, we input conditions which are based on Italy blackout in 2003 to the proposed model. The numerical results imply that even if a network itself is robust against cascading failure, vulnerability can be increased even when the network has weak interdependency with another network. It is necessary for the assessment of the vulnerability of interdependent networks to take properties of interdependency into consideration.

    Due to an increasing severity of recent disasters, shelter site selection and evacuation planning have become an essential function for the purpose of helping at-risk persons to avoid or recover from the effect of a disaster. Therefore, this study aims to propose an integrated mathematical optimization and fuzzy analytic hierarchy process for shelter site selection and evacuation planning. The mathematical models are formulated under different constraints and model types, in which the objective of each mathematical model is to minimize the total travel distance. The mathematical models are coded and run in optimizer tool for creating plans. Then, Fuzzy Analytic Hierarchy Process is applied to choose the appropriate plan under uncertainty and vagueness of the expert's opinion. A numerical example with a real case study of a Banta municipality in Thailand is given to demonstrate the application of our conceptual model. This study will be great significance in helping decision makers consider placement of emergency shelters and evacuation planning with respect to both qualitative and quantitative measurement. Moreover, our study can be a guide of the methodology to be implemented to other problems as well.

    The evacuation environment from the tsunami was changed significantly along Sanriku coastal region because of reconstructions of land use, transportation infrastructure and tsunami evacuation facilities. The evacuation to the nearest evacuation place does not necessarily mean that you can escape the tsunami flooded area quickly. Rather than the evacuation to the nearest evacuation place, the evacuation to the outside of the tsunami flooded area by use of the shortest distance route is effective to evacuate from tsunami. In this study, we analyzed the applicability of the procedure of evacuation to the outside of tsunami flooded area at fast. Through the analysis of the tsunami evacuation route before the Great East Japan Earthquake and also after the completion of the reconstruction project, we clarified the applicability of the procedure of escaping from the tsunami flooded area and evacuate to the evacuation place.

    Evacuation planning and shelter site selection are the most important function of disaster management for the purpose of helping at-risk persons to avoid or recover from the effect of a disaster. This study aims to propose a stochastic linear mixed-integer mathematical programming model for improving flood evacuation planning and shelter site selection under a hierarchical evacuation concept. The hierarchical evacuation concept is applied in this study that balances the preparedness and risk despite the uncertainties of flood events. This study considers the distribution of shelter sites and communities, evacuee's behavior, utilization of shelter and capacity restrictions of the shelter by minimizing total population-weighted travel distance. We conduct computational experiments to illustrate how the proposed methodical model works on a real case problem in which we proposed Thai flooding case study. Also, we perform a sensitivity analysis on the parameters of the mentioned mathematical model and discuss our finding. This study will be a great significance in helping policymakers consider the spatial aspect of the strategic placement of flood shelters and evacuation planning under uncertainties of flood scenarios.

    The economic value of water concession project depends on two major factors, unit price of water and the number or the rate of connection. If the government provides appropriate level of unit price or the number of connection as a requirement in a concession contract, the information of technology for water provision is necessary. However, it is rate for the government to have sufficient information of technology owned by private companies. Therefore, ‘technology-proposal bidding system’ under which bidders propose both of unit price and the number of connection is often applied. This paper analyzes the economic results under two typical award systems under technology-proposal bidding system, i.e. the lowest price award system and the most number of connection award system. In addition, the strategic hold-up behavior of concessionaire after signing the contract is analyzed. Based on the analytical result, the policy implication on the pros and cons of two award systems are discussed.

    Recently, the study of extending the service life of bridges has gained attention. Many bridges have been built during high economic-growth periods, and have reached their service life. Therefore, their rebuilding and the extending of their service life must be considered. Within this situation, local municipal governments are also conducting regular inspections once every five years as part of preventative maintenance, rather than performing corrective maintenance. In this study, we will shed light on which bridges are most prone to rapid deterioration by using data from the regular inspection of bridges. We will do this by calculating the deterioration rate from inspection data from two inspection cycles in order to determine the environmental factors that affect the deterioration rate. In regards to analysis methods, we used Hayashi's Quantification Method Type I to examine the level of influence each factor has on the deterioration rate of concrete girder.

    Recently, a plan based on the concept of “Compact and networks” is progressing in societies experiencing a population decline. However, planning has been promoted in municipalities because of the influence of decentralization. Therefore, it remains doubtful whether city planning has consistency from a wide viewpoint. The purpose of this study is examination, from a wide viewpoint, whether a municipal master plan has consistency. To achieve that purpose, we create a consolidated map of a municipal master plan by particularly addressing the future urban structure in a municipal master plan. Because of the consolidated map of the municipal master plan, results show that each regional plan is fragmented. Additionally, results suggest that it is necessary to match the plan in each municipality.

This research specifically analyzes the causal relation between the community environment and residents' physical and mental health. Therefore, this study applied a questionnaire about self-health awareness and physical health, community environment, daily routine, etc. Additionally, the research uses health indexes such as body mass index (BMI) and health-related quality of life (HRQOL) as evaluation standards. Results suggest the following. 1) An improved community environment, such as satisfactory public transportation system or public garden, tends to be non-obesity and foster a healthy mental state. 2) Health-awareness directly affects residents' physical and mental health.

    Intensive population migration of the university graduates from countryside to city has been observed for a long time. Currently encouraging them to find the employment in the regions where the university is located is an important policy for local government as migration is a contributing factor of depopulation. To make the policy, it is necessary for the government to assess status quo of local employment of the students and identify the characteristics of the region. In this study, the method of assessment is developed using latent class analysis. Also we compare prospect and actual number of employment, the factors that affects the employment is specified. As the result, the strategy for each region is suggested empirically.

    Improving local government planner attitudes is important to promote compact city policy. Existing studies have demonstrated the effectiveness of one-shot lecture (OL) for awareness improvement. For this study, we administered an attitude survey related to compact city policy and analyzed relations between acceptability and individual attributes or difficulties in realizing compact city policy. Thereby, we ascertained OL effects more specifically. Results show the following. 1) Planners with low acceptability consider budgets and expert knowledge as difficulties that can be improved by providing fundamental information related to compact city policy. 2) Planners with originally high acceptability show a slight change in improvement and consider problems at sites such as a lack of understanding of citizens, and coordination among departments as difficulties. 3) Planners who are not improved acceptably even if OL is implemented consider physical problems such as opposition of lawmakers and lack of human resources as important difficulties.

    “Compact Villages” have been set in rural areas under the “Compact plus Network” of national land policy. However, the government has not indicated how to choose Compact Villages. This study was undertaken to ascertain suitable locations for Compact Villages and to consider how to choose Compact Villages. From our analyses, we identified the possibility that not only a distribution of daily facilities, but also the social capital produced by residents can maintain standards. We presented various meanings of Compact Villages occurring from variation of the function and distribution of daily facilities produced by differences of chosen standards. Especially, the improvements of road network infrastructure will not bring benefits to all Compact Villages. Rather, it will promote the selection of fewer Compact Villages. This suggests that policy of “Compact plus Network” may have paradox.

    In recent years, the tourism industry has drawn attention as a means to revitalize cities. In this paper, when using local gourmet as tourist attractions, we examined a method to measure its activity quantitatively. Since we thought that the spatial accumulation of restaurants that served local cuisine would influence regional revitalization after the previous research, we analyzed the points of addresses of local cuisine gourmet restaurants using spatial statistics. As a result, in many cities the local gourmet stores are not located spatially randomly. It can be classified into three groups of locating such as gathering in one place, sitting to a certain distance, and gathering in multiple places. We can also compare and classify cities with regard to similar store placement.

    Japan is now facing with the long-term decline in population. Depopulation also brings with scattered housing in urban area which sometimes lowers quality of life of the area. These effects must appear more clearly in small towns/villages and their local society as a whole. Japanese government implements policies such as ‘Settlement and Independence Area plan’ (Ministry of Internal Affairs and Communications) and ‘Compact plus Network’ in National Spatial Planning (Ministry of Land, Infrastructure, Transport and Tourism) so as to secure a minimum variety of urban functions necessary for daily lives. Their basic idea is to maintain minimum population and its density of central area, by inviting urban residents from surrounding areas and by enhancing the connecting transport network with surrounding small local towns. This study clarifies the changes of urban population density and connections of surrounding towns by transport network in the last decade. Tottori City and its surrounding areas, constituting the greater Tottori urban area in the eastern Tottori prefecture in Japan, are focused as the case study.

    Many local governments nationwide attempt to develop a comprehensive management plan for public facilities due to the aging of these facilities and increase in expenses for maintaining and renovating them. One of the key issues for the integration and abolition of public facilities is whether the government can gain the acceptance of local residents. The purpose of this study was to survey residents' attitudes towards the integration and abolition of public facilities in their communities and examine psychological factors influencing their acceptance for such a management plan. The results showed that those who disagree with the abolition of public facilities in any conditions tend to recognize relevant issues related to public facility management, trust the government, and have strong place attachment and sense of belonging to their communities. Implications of the results for promoting public acceptance and consensus around a management plan for public facilities were discussed.

    The self-organized health promotion is expected in the project of healthy city planning. Therefore, collaboration and participation of citizens are strongly required to develop the healthy city planning. The questionnaire survey is conducted to the citizens of Suita city concerning with real healthy city planning. In the study, the project called as Northern Osaka Health and Biomedical Innovation Town (NohBIT) is discussed to summarize the attitude of collaboration to the project referring to health condition and health attitude of citizens. It is reported that many citizens recognize the individual health problem and make daily effort to their own health. On the contrary, it is known that the participation of citizens is rather difficult even though the collaboration of citizens tends to be accepted rather easily. The different consciousness of residential area is analyzed. The response patterns of the residential area to the questionnaire are classified with fuzzy clustering analysis method. The spatial relation between the location of project and residential area, life style of the areas are affected to the consciousness of collaboration and participation. The change of consciousness of citizens is estimated with the neural network model. The impact of health policy can be evaluated for future design of the project.

    Recently, in order to obtain the planning information such as a compact city policy, the use of micro-geo data has been applied effectively. In this study, we develop a method to estimate the hourly population inflow during downscaling the spatial analysis resolution by using the RBF Network with respect to the two mobile data of the mobile spatial statistics and the urban planning basic survey. In this study, a model is formulated that estimates the population inflow of each mesh from the total floor space by building application counted on the regional mesh level 3 (1km square grid) scale for estimating the population on the regional mesh level 4 (500m square grid) scale. According to the spatial visualization of the obtained population distribution by this method, it can grasp the distribution of population easily in which it is better than estimating with 3rd scaling.

    This manuscript analyses spatial movements of people living in ancient Kyoto, Heian-kyo based on various literature. For Heian-kyo, although the geometric configuration of roads and the block size are well known, living and working locations of common and noble class people and their spatial movements have not been investigated. The study first estimates the land use and population densities for every block focusing on the middle period of Heian. Then, based on the estimated nighttime and daytime population, OD volume is obtained using Entropy method and finally link volumes are estimated using the Dial's algorithm. Furthermore, movements of noble class people on New Year's Day in year of 1027 is recaptured based on Shoyuki, diary of Fujiwara no Sanesuke.

    In this study, we developed a diffusion model of shared fully-automated vehicles (LV5) and applied this model to the impact analysis of vehicle price, urban extent, population and travel speed on the LV5 dissemination. As a result, we found 1) the LV5 is expected to obtain the certain share of demand even under the 10-fold high cost of conventional personally-owned vehicles, 2) the share of LV5 vehicles is sensitive not only to the vehicle cost but also to the urban extent and travel speed, 3) urban population does not affect the LV5 share, 4) the high share of LV5 can be achieved even with the high vehicle cost if the urban extent is compact. These results indicate that the shared LV5 service should be introduced in the small cities with compact urban extent initially if the cost of LV5 is expensive. To achieve the higher diffusion rate of LV5, the shared service should be introduced in large cities according to the cost reduction of vehicles.

    Probe person survey has received great deal of attentions, as it can automatically collect traveler's spatiotemporal traces using sensors like GPS, making a long-term travel survey easier. However, it is still difficult to collect all of the survey results automatically, because trip purpose—one of the most important characteristics of travel—is not possible to be identified based on such sensor data itself, making a long-term survey costly. This study proposes trip purpose estimation method based on automated sensor data and minimal manual questionnaires, in order to reduce survey burden on respondent and enable a long-term survey. In the proposed method, trip purpose is estimated by a classifier with sequential learning. Specifically, if the estimation confidence is high enough, the estimation result is considered as a survey result. Otherwise, the method asks actual trip purpose to the respondent, and then manually answered trip purpose is used to update the classifier. As results, the method is expected to reduce survey burden on respondents by automatically estimating purposes of recurrent trips, while keep data quality by asking purposes of irregular trips. Empirical features of the proposed method is validated by emulating the method on actual survey data.

    We verified that the geometric factors such as road width, the number of lanes, and the size of intersection have a significant impact on route choice behavior of freight trucks. We estimated parameters of a route choice model, where the explanatory variables are the number of lanes and the size of intersection, by using Maximum Overlapping Model, which is designed to determine parameters so as to maximize overlapped length between estimated passage and actual passage of freight trucks on the general road networks. As a result, we successfully demonstrated that using the size of intersection as one of the explanatory variables can lead to 1.8 times more accurate estimation than ordinary route choice models, such as “the least travel time model.”

    Recently, local cities are suffering from rapid depopulation. The outflow of young people tend to accelerate the population decrease. Also the rapid spread of smartphones and the shift to compact cities have been changing human leisure activities. The purpose of this study is to investigate behavior of and attitude towards leisure activities of young people. As the result of a web-based questionnaire, it was found that some young people wish to increase the volume of leisure activities and are not satisfied with leisure opportunities. In addition, the leisure activities are affected by their age, gender, marital status, having or not having children, youngest child's age and living location. It would be important to provide leisure activity opportunities in local cities taking into account of individual socio-economic characteristics of young people.

    Estimation of pedestrian behavior in high-resolution is expected to advance the facility placement along the street. Generally, when capturing the walking trajectory as high resolution, it does not exist directly above the road network. However, the conventional map matching method, in which measurement coor- dinates are matched onto the network, has a problem from this viewpoint. Therefore, in this research, we propose a method to explicitly consider errors of network on continuous space. We sequentially estimate the deviation of the walking trajectory from the network as a latent variable by the GNSS measurement, taking the positioning error into account at the same time. From the measurement with error, we for- mulated a trajectory estimation which can describe the movement on the network and does not limit the actual position on the network. We showed the usefulness of the proposed method through application to simulation data in multiple settings.

    We focused on road users' evacuation of when the Nankai Trough huge earthquake occurs and analyzed the relationship among individual attributes, understandings of disaster, prior information for tsunami disaster and evacuation behaviors by using questionnaire survey data. From the results of analyses of covariance structure for coastal road users' consciousness and behaviors, it is revealed that the prior information conjures up tsunami disaster in their minds but prompts their speedy evacuation behaviors by car. It is also found that the persons, who have many knowledge of weather warning and evacuation information or live in the area affected by an earthquake and tsunami disaster, tend to evacuate promptly in spite of the presence or absence of priori information while the persons who live in inland and safe area but become potential coastal tourists aren't tend to evaluate quickly. Thus, it is necessary to provide the information not only for the knowledge of disaster but also for promoting evacuation behavior by foot to potential coastal tourists in order to avoid the tsunami disaster risk.

    The purpose of this study is to estimate the origin-destination matrix of urban area by using the activity simulation. The tour-based behavioral model which considers the interrelation of the trips was constructed by Kofu PT survey and applied it to forecasting the travel by the micro-simulation in Kofu. The estimated OD matrix by the simulation is not precise, so that we estimated the OD matrix by assimilating the observed OD matrix of Person trip survey to the simulated OD matrix. After applying the particle filter which is one of the flexible assimilation methods, the precision of the OD table was improved significantly. This study showed that data assimilation is one of the practical approaches to improve the micro-simulation of travel behavior in the big-data era.
