    Summary: In Japan, many community bus systems have already been tried after the community bus in Musashino-city, called “Mu-Bus” was operated in 1995. Most of these services depend on subsidies from the local municiparities and many of them have now be forced to discontinue due to budget cuts of the subsidizing local government. As a case study of a successful operation of a community bus system, the cost analysis of Sumiyoshidai Kurukuru Bus system in Kobe, which is operated without public subsidy, has been performed. In the cost analysis, formulas for estimating various costs, which are applicable to other bus services, are proposed. From the cost analysis and sensitivity analysis of Kurukuru Bas, the reasons for its success have been found to be its relatively short service length of eight kilometers.

    Summary:In Japan, land price would not be expected to rise rapidly as before. Therefore, the value of urban redevelopment projects would depend on cash-flow of income gain more than capital gain. The value of income gain would be so sensitive to uncertainty such as floor rent and vacancy rate etc. In addition, recent researches indicate that flexibility of decision making on projects, which is called real option, should be considered in project evaluation. Kariya (2001) and Kawaguchi (2002) developed evaluation methods for real estate projects including uncertainty and real option. Kariya (2001) developed standard method considering uncertainties of floor rent and vacancy rate on building usage stage, and Kawaguchi (2002) expanded it to evaluate various uncertainties on from project planning stage to building usage stage. In this study, we expand those methods of Kariya (2001) and Kawaguchi (2002) as to evaluate urban redevelopment project including real option of multiple staged constructions which can be found in real world. Then the calculation method is presented using Dynamic Discount Cash Flow Method. Finally in application the usefulness and feature of the method are proved.
  • Optimization Method for Population Distribution Using Land-Use and Transport Model of CUE Type, TOMITA Yasuo, TERASHIMA Daisuke, Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 21(1),225-232, 225 - 232, 2004
    Summary:Many cities in Japan are facing such various problems as economic recession, population decrease, shortage of financial resource, decline in city centre, and global and local environment problems. Compact city policies are required in order to lessen those problems. However we do not have a method to examine what urban structure is optimal and how the urban structure can be achieved. In this study, the method was developed by expanding CUE model (Computable Urban Economics Model), which was developed by Mutou and Ueda et. al., to an optimization model with objective function of social surplus, and then a modified Fowkes's method was applied for the optimization problem. Finally the developed method was applied in Nagoya metropolitan area, and the optimal population distribution to be achieved by income subsidy to households was found, which proved the applicability of the developed method.
  • An Attitude Survey on Supply and Demand for Fixed Rental Term Housing and Modelling of their Behaviours, YAGI Hideo, TOMITA Yasuo, TERASHIMA Daisuke, The Japanese Journal of Real Estate Sciences, The Japanese Journal of Real Estate Sciences, 16(4),136-142(4), 136 - 142, 2003
    Summary:In this study, an attitude survey on supply and demand for fixed rental term housing (FRTH) is implemented. Then the logit models for the supplier's/demander's choice behaviours for fixed rental term housing are estimated. The results are summarized as follows:<BR>1) The diffusion of the FRTH to demanders is not enough, then younger generation prefers the FRTH to usual rental housing, and for the generation, the shorter rental term housing tend to be preferred, which should be considered in the advertisement and for the diffusion of FRTH in future.<BR>2) Owners of the older rental housing hope to change to the FRTH in order to rebuild at an adequate period. However, it would be disturbed, because the aged persons tends to live in the order rental housing and they would not prefer to change to the FRTH.<BR>3) Demanders prefer the fixed term of FRTH is between 4 and 6 years, on the other hand, supplies prefer that the term is between 2 and 4 years, whose deference should be adjusted through the FRTH market to be developed well in near future.<BR>4) Finally, the logit models of demanders and suppliers were estimated, which are useful for predicting the amounts of demand/supply for the FRTH.

  • Building Spatial Distribution Model for Evaluating Urban Space in Blocks, TERASHIMA Daisuke, TOMITA Yasuo, Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 20, 427 - 432, 2003
    Summary:Urban landscape is largely affected by land-use patterns, the design of individual buildings, and the spatial harmony among these buildings. In this paper, we have developed a building spatial distribution model for visualizing urban space in blocks. In this model, it is assumed that the developers determine rebuilding and a choice of building type (i. e., land-use type and building height) according to the expected profit. Their decision probability is formulated by disaggregate logit model with explanatory variable of the expected benefit. Then the simulation method and its algorithm are developed. Finally, the validity test of the model is implemented in blocks in the city center of Nagoya.

D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 17, 765 - 769, 2000
    Summary:In the UK, the paradigm of urban transport planning changed from &ldquo;predict and supply&rdquo; to &ldquo;predict and prevent&rdquo; around in 1990, and then the policy is announced through the Transport White Paper in 1998. In this paper, why the paradigm-shift happened is clarified by the review of the context of the urban planning since 1960's. Then Based on the transport white paper, the features of new transport policy are examined in order to have lessons for the transport policy in Japan.
  • A Surplus Soil Coordination Model between Construction Sites with Uncertainties Related to Construction Commencing Time, Duration and Soil Volume, TOMITA Yasuo, TOKUNAGA Daisuke, Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 17, 129 - 134, 2000
    Summary:Some surplus soil coordination models between construction sites have been developed in order to make efficient soil transport plan for recycling of surplus soil. However these models can't consider the uncertainties related to construction commencing time, duration, and soil volume, except of Minami and Simazu Model (1988) that can deal with the only uncertainty of construction commencing time. In this study, a model dealing with all of the above uncertainties was developed by improving the Minami and Simazu model. Then the model's applicability was shown through the application.
  • The Period Hierarchical Calculation Method of Surplus Soil Transportation Model by Applying Dantzig and Wolfe's Decomposition Principle, TOMITA Yasuo, TERASHIMA Daisuke, Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 14, 79 - 85, 1997
    Summary:In metropolises, many projects are under construction during the same and overlapping time periods. To convey soil for the projects, much heavy lorry traffic is generated, which causes more seriously urban environmental problems. Some models are developed to coordinate the projects in order to lessen the traffic. However these models can not be applied in practical cases involving many projects because of the limitation of computer memory storage.<BR>In this paper to relax the restriction, a periodical hierarchical calculation method of a surplus soil transport model which was presented by Tomita and Terashima (1996), is developed by applying Dantzig and Wolfe's decomposition principle, and the availability of the calculation method is proved in case study.

    Summary:Disposing a large quantity of surplus soil, generated by constructions, has become problems of the increase of transportation cost and lacking of disposal sites. On the other hand, supply of soil to some construction sites have also become a serious problem. Therefore the recycle of surplus soil from a construction site to another construction site is necessary.<BR>This paper proposes a regional coordination model for recycle use of soil between construction projects. Then the application is presented by useing the hypothetical data.
  • Surplus Soil Transportation Model Considering the coordination of Starting Time and Period of Constructions, TOMITA Yasuo, TERASHIMA Daisuke, Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), Journal of Japan Society of Civil Engineers, Ser. D3 (Infrastructure Planning and Management), 13, 331 - 337, 1996
    Summary:Disposing a large quantity of surplus soil, generated by constructions, has become proble ms of the increase of transportation cost and lacking of disposal sites. On the other hand, supply of soil to some construction sites have also become a serious problem. Therefore the recycle of surplus soil from a construction site to another construction site is necessary. It is necessary to coordinate the starting time and period of constructions in the planning stage. This paper proposes surplus soil transportation model, considering the coordination of starting time and period of constructions with &ldquo;mixed 0-1 integer linear programing model&rdquo;. The application is then presented by using the hypothetical data.
  • he Transport Behavioral Analysis after Hyogoken Nanbu Earthquake for the Reduction of Motor Transportation, Tomita Yasuo, Hayashi Yoshitsugu, Ieda Hitoshi, Nakagawa Dai, Journal of the City Planning Institute of Japan, Journal of the City Planning Institute of Japan, 31(0), 775 - 780, 1996
    Summary:TO PREVENT TRANSPORT SYSTEM DOWN AFTER GREAT DISASTERS, IT IS NEEDED NOT ONLY AN INCREASE IN RELIABILITY OF TRANSPORT FACILITIES BUT ALSO TRANSPORT DEMAND CONTROL. HOWEVER TRANSPORT AFTER HYOGOKEN NANBU EARTHQUAKE IS NOT CLEARFIED AS A WHOLE. IN THIS STUDY THE PERSON TRIP SURVEY IS EXECUTED TO CLEARFY THE TRIP GENERATION, ITS ATRIBUTES AND THE POSSIBILITY FOR THE REDUCTION OF MOTOR TRANSPORT AFTER THE EARTHQUAKE. CONSEQUENTLY IT IS POINTED OUT THAT TRIPS FOR FOOD AND WATER, ACCOUNT TO ABOUT 60% AND IT IS EFFICIENT TO REDUCE THE TRIPS BY CHANGES FROM PRIVATE CAR TO COOPERATION CONVEYANCE ORGANIZED PUBLIC SECTOR. IF THIS POLICY WOULD BE EXECUTED ENOUGH, IT WOULD BE POSSIBLE TO REDUCE 34% OF MOTOR TRIP GENEATION IN A WEEK AFTER THE EARTHQUAKE. BY EXECUTING SOME OTHER POLICIES TOGETHER, THE TRIPS WOULD BE REDUCED TO ABOUT 50%.
  • Graphical method for determining forms of utility functions of disaggregate logit models., TOMITA Yasuo, HAYASHI Yoshitsugu, OKUDA Takaaki, Doboku Gakkai Ronbunshu, Doboku Gakkai Ronbunshu, 1988(395), 125 - 128, 1988
    Summary:This paper introduces a procedure for plotting partial residuals for multinomial logit models. This provides a method for graphical determination of utility functions of disaggregate logit models which offers significant advantages over the established &ldquo;black box&rdquo; method. An empirical example is developed in the context of revealed dwelling type choices in the Nagoya metropolitan area which shows the usefulness of the method.
  • A model for zonal forecast of life cycle progress, residential location and population attributes using random utility models and a micro-simulation technique., HAYASHI Yoshitsugu, TOMITA Yasuo, Doboku Gakkai Ronbunshu, Doboku Gakkai Ronbunshu, 1988(395), 85 - 94, 1988
    Summary:This study is an attempt to develop a forecasting method of population attributes by zone in a metropolitan area. Random utility models are used to formulate each event of household related to individual's life cycle and residential relocations. As the forecasting method, a micro-simulation technique, which can chase individuals' behaviours and can provide flexible aggregation, is employed. The validity test and policy tests proved the advantages of the model, compared with existing models.
