The purpose of this paper is to analyze where photovoltaic may be introduced by extending a simple Alonso model. First, we demonstrate theoretically the relationship between the construction of photovoltaic and the distance from CBD by using an explicit distance-rent function. Second, we predict empirically the conditions for establishing the photovoltaic along Joban Line districts, by using actual rent data.

In this paper quantitative method about buildings and landuse pattern is discussed by distance among near buildings(DNB). We analyzed following three steps. Firstly, we figured a calulating algorithm, secondly we analyzed characteristics of 4 index about DNB and statistical relations of DNB to building area ratio by each lot unit , thirdly we discussed combination patterns of DNB average and urban space pattern. We considered the worth of DNB as urban planning method following two points : 1) DNB average and Building area ratio were pretty independent each other. That is to say, DNB did not show density but arrangement. 2)DNB would express not just near buildings pattern and small vacant apace but also lot-street patterns.

This paper summarizes the results of way-finding experimental study about the way-finding from the main subway station to the surface goal in Osaka-city. The human behavior was recorded by the video camera and thinking-aloud protocol data was recorded by the IC recorder. The group that is superior in sense of direction acts in expectation, but the other inferior group doesn't. Comparing the former with the latter, the latter locked at the sign board many times and also for a long time. It was considered that the former did the way-finding with imaging the space, but the latter acted without the space imagination.

This study focuses on the differences of wayfinding behavior of foreigners and Japanese at Umeda area. 111 samples of them were unobtrusively tracked until each destination and interviewed with regard to their reference frames, reasons, and difficulties in available cases. Average quotas of a) times of lostness, b) times of lostness per 100 meters, c) rate of extra walking distance, d) time and e) speed clarified that foreigners needed more extra compensative behavior to arrive a destination and paid more psychological pressure than native Japanese. Cognizing spatial structure of city environment is more difficult because of different social and cultural context. Quality and quantity of guidance at information centers need to be more efficient and helpful for all people.

The purpose of this basic study is to describe some temporal characteristic aspects of action occurrence from the point of view of Act-finding in regard to strolling behavior in underground street area. Some types of actions have been gotten from the videotaping records by the observation: Eyes action includes 'gaze', 'look around' and 'look back'; walking action includes 'wind', 'return', 'turn', 'stop', 'accelerate' and 'slowdown'.The total of the recorded actions by the experimental investigation is 782. Eyes action is 421(53.8%) and walking action is 361(46.2%). That is, eyes action and walking action occur at the about same rate. The log-log graph of the interval time of actions and the number of times decreases with repeating increase and decrease. The result clearly shows that the relation between the interval time of actions and the number of times is fractal (the fractal dimension is 1.07).There is striking difference between eyes action and walking action because the occurrence of eyes action shows linear-like decrease and that of walking action shows logarithm-like decrease as much as interval time gets long.

In the present paper, we discuss the measure of the point pairs whose distance are less than a distance r in a given area. By differentiating this measure with respect to r, we get the function f(r) which is called by distance distribution. Using formulae in Integral Geometry, we get an approximate polynomial for the distance distribution in an arbitrary convex region. The approximate expression consists of the area S and the perimeter L of the region and have good fitness to the numerical distributions of governmental districts in Tokyo.

In this paper, we introduce a sector-shaped city associated with the infinitely dense circular-radial road network system. Assuming that trip end points are uniformly and mutually independently distributed over the city, we calculate the circular-radial distance distribution. Although the process of calculation consists of the quite complicated classification of formulas, the final result is proved to be very simple one. According to this result, we calculate characteristic values. Our output will be applied to analyze the efficiency caused by the shape and the metric of cities.

In this paper, we consider the optimal location of a single bridge that minimizes the mean and the variance of the distance between uniformly and independently distributed points within a sector-shaped city whose transportation network consists of a radial-ring system of roads. We examine the effects of a bridge on the enhancement of movement efficiency over a city from a geometrical point of view. Our results indicate that although the overall mean and variance of the distance cannot be reduced dramatically the addition of a single bridge have great potential in relieving the traffic congestion of the central city area.

In this paper, we first discuss theoretically the differences between the ordinary Huff's model and the Huff's model associated with the negative exponential gravity function. If you use the ordinary Huff's model, the frequency of the choice of stores does not depend on the speed of movement in the region. However, if you use the negative exponential Huff's model, the frequency does depend on the speed. After describing such theoretical aspects in detail, we formulate some types of gross sales calculation models for two stores on one-dimension region. Adopting the negative exponential gravity function to these models, it is proved that the sales for each store are expressed as a monotonous fuction of the speed of movement. Our results can be used to analyze the effect of the development of transportation systems on regional commercial activities.

The tendencies of the phone traffic data seem to follow the gravity model as a whole, but if we analyze details, the tendencies are very complicated. We use the gravity model as a basis, and using the concept of backward calculated distance , we show the regional structure of telephone calls. We show a new visualization method using the multi-dimensional scaling method by means of virtual distances on purpose to general analysis. By our analysis, we clarify the specialness of the regional structure in telephone calls.

Data are collected through a questionnaire survey of firms and their employees. Business relations of firms are mostly constructed within Kyusyu region, but important customers are often located in metropolitan areas. So employees are often visit customers located in metropolitan area for a business meeting. Many employees are hired from schools or firms located in same prefecture as an employer, however, part of highly educated and well-experienced labors are employed from metropolitan areas. We also examine the workers stationed at a customer's office.

Urban block is directly related to road networks in city. If buildings were arranged to maintain efficiency of traffics between each other building division of urban blocks would be expected. This study aims to show restraint of detour ratio of paths or average path distance can divide urban blocks and maintain efficiency of road networks. Differences of effect by regulation were tested from experiment using a grid based urban growth model on computer. Detour ratio regulation had a good effect and it was robust to different type of estimation for location. Average path distance regulation also had effect, but it also had second side effect that restrains growth of city.

This paper aims to visualize the nodal structure based on the Cluster Analysis Method. The similarity matrix based on OD traffic flows generated in each zone is used to calculate the dendrograms in Cluster Analysis. The methodology exploits the algorithm of visualizing the nodal structure based on the directed tree and adjacency matrix of Graph Theory. The algorithm of visualizing the nodal structure is applied to the journey-to-work travel in Sapporo City using person trip data for 1972, 1983 and 1994. Cities grow in population and employment and the relative location of homes and workplace changes along with journey-to work trip lengths. It is possible to visually grasp that the changes of the land-use pattern affect the journey-to-work travel through the nodal structure.

In line with the private oriented economic vitarization, local government is expected to take more flexible land use leading measure such as district based taxzation and subsidy, adding to the present rigid land-use reguration measures. This paper aims to build a land-use model being able to estimate the effect of such monetary measures. Based on observed land price data, bid rent functions of several types of land-users in monetary term are estimated, those are embedded into a logit type random bid rent model. The proposed model, when estimated with geographical data for the 100m grids in Higashi-Hiroshima City, shows good reproductivity of land-use as well as land price. Simulation analysis using the model shows the influence of land-use taxation.

This paper focuses a facility location model assuming that demand for service originates from users traveling, which is not directly for the purpose of obtaining the service, as is seen in actual behavior. We combine such a flow-demand location model and the traditional median model. Effect of change in jobs-housing spatial structure on optimal facility location is analyzed considering two types of demand: commuting-based demand and home-based demand. With some examples on an ideal triangular lattice urban network, it is shown that facility location decentralizes toward outer suburbs as spatial correlation of home and workplaces gets stronger, or as home-based demand gets more dominant.

Individuals conduct different activities conditional on their limited time and monetary resources etc. In general, they do not evaluate these activities equally because of their different priorities. Performing one specific activity reduces the probabilities of performing others. Longer travel time also has a negative influence on the occurrence of the activities. However, conventional time allocation models do not consider this kind of interaction clearly. Therefore, this paper proposes a new time allocation model based on multi-linear utility function. This function is a linear function with subject-specific terms and interaction terms, where subject refers to the activity and the interaction terms express the interaction among different subjects in a multiplicative form. The effectiveness of the proposed model is confirmed based on an activity diary survey collected in Sapporo city in 2002.

In order to do this,we use the random-graph theory that is the combination of graph theory with probability theory. We have to show that nlogn is the threshold function for connecting every n members, in other words, nlogn the necessary and suffient number of edges for spanning n vertices. We would like to discuss the conclusion of compairing the theoretical result with the computational result.

Five different distributions of population and employees are set up based on three types of urban forms; concentration in city center, spreading to suburbs and dispersion to suburbs. The more population is dispersed to suburbs of the city, the higher transportation energy is consumed. It is found that the development both of housing areas and working places in a suburb has possibility of curbing the growth of transportation energy consumption.

The walking distance to the bus/tram stop or station is one of the important travel resistances, which should be reduced for attracting people from private vehicle to public transport. This study aims to estimate the loss of potential uses which locations and facilities of bus/tram stops cause and to address some improvement measures and their effect. Through comparison of various type of stops and analysis in case studies, it was showed that locations and facilities of bus/tram stops cause increases of walking distance and reduction of potential users living in walking range from stops. These impacts appears clear in case of setting acceptable walking distance as short as 250 meters. Population in walking range could be improved at least two or three times larger than before, through moving bus/tram stop to nearby pedestrian crossing.

The policy of Tokyo Metropolitan Government in terms of road planning, which is the second point, has been adapted to the rapid changes of the socioeconomic state of the country. Principal purposes of amendments of road city planning in each decade have been changed from traffic volume management to traffic environmental solution, that to the related amendments to large-scaled urban renewal project. During the 40-year period, major changes of citizen participation system and the city planning tools have aiso been made.

Congestion charge policy is most effective one among transportation demand management policies. Recently, road pricing that is one of the congestion charge policies is examined to be introduced into heavy congestion roads in Tokyo. This policy has influence on modal split between road and railroad, and then the government can use the collected congestion charge for improving railroad service level. In this paper, we have proposed theoretical models to determine simultaneously home departure time and modal choice with / without congestion charge. And, we have analyzed influence of congestion charge and return schemes on modal choice between road and railroad. From results of numerical simulation, we have shown that scheme of return to other mode doesn't improve utility. Furthermore, scheme of pricing to railroad commuters is more effective.

The models are estimated using structural equation modeling and based on the 1995 UTDM/BEIP Home Interview Survey. The results highlight the key roles of car ownership, gender, education level and monetary costs of travel in explaining the observed level, chance and intensity of mobility. It is also indicated that the effects of urban activity density and distribution becomes more significant as household income level increases and personal and household characteristics have less significant power for the highest household income group.

In European countries and USA, environmental awareness of car sharing members is higher than that of others. And long term members increase public transportation trips. The objective of this paper is to estimate the car sharing demand model, with environmental awareness and environmental activities in daily life. We define the index of environmental awareness from the survey of daily environment activities. The demand model was estimated that included the characteristics of commuters, the index of environment awareness and the level of car sharing service. This model includes that, as the index of environmental awareness rises, willingness to pay for car sharing is enhanced.

In the revision of the determination of "the Disabled" in 1999, it was determined in 3 viewpoint, impairment, activity limitation and participation restriction. The aim of this determination is said that the disability depends on an person's function of daily life not on his physical conditions. According to this, a person in a transportation situation that he can not achieve his autonomous activity because of lack of proper transport method, might be judged in disability. The purpose of the present paper is to make clear the importance of activities of elderly and disabled people, and the transport situations that they are put.

Information systems for placing and receiving order of commodities have been developed to improve the commercial business activities. However, it is difficult to quantify the influence of information systems to the logistics activities. This study tries to clarify the direct and indirect effects of information systems to the logistics activities by using information systems placing and receiving. Direct effects improve the commercial business activities while indirect effects influence the logistics activities. It was found out that among the direct effects of EOS (Electronic Ordering Systems) are decreased in the percentage of manpower and ratio of error to commercial business activity. On the other hand, its indirect effects is expressed by the reduction of lead time to the logistics activity.

In the case that imported shipping cargoes are handled in a logistics center located in the inland suburbs, the transportation seems to be complicated and have long distance. The purpose of this study is to reveal the characteristics of this complicated location behavior of logistics centers in waterfront or inland districts. In this cost analysis based on interviews, it is implicated that it is necessary to reconsider location regulations, support constructing facilities and improve commuter access in waterfront districts to reduce inefficient transportation and make the efficient use of waterfront districts.

The area of Otemachi-Marunouchi-Yurakucho is the first and biggest CBD in Japan. This area is going to bere-developed into a large-scale international business and commercial center of Japan. It is expected that illegal of parking pick-up and delivery services"on-road"will cause serious traffic congestion than ever. Social experiment of parking management and co-operative delivery services was conducted in this area aimed not only to decrease the volumes of truck traffic and air pollution but also to test the effectiveness of the freight delivery system. Underground truck parking spaces and freight stock point had been made for the experiment. Although the experiment was successful and proven to be effective to improve traffic situation as well as enviromental problem,the challenge of cost allocation to introduce these services seems unresolved.

An economic evaluation model for TDM package policies composed of Road Pricing and P & R system is proposed. Our model is based on the urban economics,which has only one CBD and residential area along a corridor connecting from suburban area to CBD,in order to analyze the effect of TDM package policies not only in the closed but also in the open city,because we want to evaluate the effect of TDM policies as an urban management policy. We can find following results;1)The TDM package policy composed of two TDM policies is more effective than an individual policy in the total travel cost.2)The TDM package policy is useful in the closed city rather than in the open city and is effective as the short-run urban management policy.

Road pricing policy is one of the promising TDM measures which can solve effectively the traffic problems such as traffic congestion and air pollutions, but it is said that the policy has income regressive effect. In or-der to evaluate the regressive effect of the road pricing policy, we construct a multi-class network equilib-rium model of the users' mode choice and route choice behaviors for the several income classes. In a simple network example, it is shown that, with the road pricing policy, lower income users will be made worse off and higher income users will be made better off. However, using the revenue of pricing for the improvement of related transport services we can compensate the loser and alleviate this income regressive effect. Finally we apply this model to the Tokyo Area and evaluate the regressive effect of proposed cordon pricing policy.

The purpose of this paper is to show commuter's attitude and behavior to change of a commutation allowance supply system to reduce private cars. Nagoya City has doubled a commutation allowance of employees who bicycle daily to work and halved it of ones who commute by car at a distance less than 5km since March in 2001. As a result the number of automobile commuters within 5km decreased 50% and the number of bicycle commuters increased 30%. 82.3% of all commuter agreed with it. Not only a cost of commutation but also attitude to environment and agreement of the policy are important factors in modal choice of commuters.

In this study, we investigated long term effects of a psychological solution called TFP, that was implemented as an transportation and environmental educational program, on travel behaviors and psychological factors that may determine automobile use. We found the interventions used in TFP had effects, as we supposed, on behaviors and psychological factors even 1 year after that intervention was implemented. This empirical results imply that TFP may be used as an effective TDM measures that are used both for restriction of automobile use and for promoting public transport use.

Recently, energy consumption by using car has been increasing. So, there are many interests in compact cities from the point of view of environmental preservation. This study aims to show effectiveness of car usage reduction by application of land-use control policy. Surveying ABC policy in Netherlands and PPG13 in England, we found out effects and problems of the co-ordination between Land-use and Transportation planning, and tried to find requirements for implementation of land-use control policy in Japan. Analysis of data from Person-trip Survey in SEIEN-urban area shows relationship between commuters' car usage and location of offices. In addition, the results obtained from simulation show that it is more effective to move office to location well served by public transportation with the amount of parking space is limited.

The main purpose of this paper is to examine the actual policy-making abilities of Local Governments, based on the findings of a survey. The findings can be summaries as follows: (1)Local Governments are obliged to form comprehensive plans by themselves due to various factors. (2)These governments are attempting to involve citizens in decision- making processes in comprehensive planning. However, they are often unaware of exactly how to do so and, as a result depend on the advice, methods, and knowledge of professional consultants. (3)At present many Local Governments are trying to become more aggressive in forming their own policies, but the situation is still chaotic.

This study aims at the present condition of the Internet use and the IC (Integrated Circuit) Card use of the middle-and old aged. We try to show the possibility of citizen involvement expansion for community development using the electronic community currency with IC card. Although middle and old aged people are tackling positively participation to the local electronic conference room, and the attendance to IT training programs, the difficulties of PC operation have barred the participation. The rate of the application of the advanced age layer of the IC card is higher than that of the young and middle age's it. Electronic community currency with IC card has the possibility of expanding the citizen involvement in community development by the middle aged and the elderly.

As the public has tended to express being involved in decision process of various facility siting which would cause NIMBY (not in my backyard) syndrome and some institutions on public participation has enforced recently, the authorities are required to secure visibility and to take accountability. European and North American countries have developed many public participation programs and "fairness" notion forms the basis of these. This paper provides a view on fairness in facility siting by literature survey in mainly sociology and social psychology. Findings from evaluating 2 examples with the framework demonstrate that deepening common understanding on potential perception gap on fairness among stakeholders in early stage would helps making successful progress of the process.
