This paper aims to discuss the relations of monitoring and modelling methods of trip maker's route choice behaviour in a transport network, and to show possible directions of model development of route choice. Previous monitoring methods based on questionnaire are not sufficient for detailed analysis of travel behaviour in space/time dimensions. A new observation method using mobile communication system is possible to trace the movement of individual route choice behaviour, The results of behavioural analysis using detailed route choice data could be applied for improving route choice models employed in network flow models such as User Equilibrium.

One of the various Intelligent Transport System (ITS) projects is Parking Guidance and Information (PGI) system development. It assists a driver to park his/her car in the city center where available parking spaces are limited. In this study, the driver's parking searching behavior under PGI system was modeled first theoretically. Then the model was applied to the driver's parking behavior in Tama Center area. The resul is supported that the driver would choose a certain parking by weighting relative expected utility for each alternative parking facility under uncertainty. The model analysis also indicated that parking searching behavior was induced if the en-route parking choice proved worse than expected in city center, which implied en-route information is more important than one near the final destination.

In this paper, we have represented a fundamental framework of a decision making model focusing on consecutive information reference processes under multiple information sources. The information value having been evaluated with the conventional aspect of behavior profits is formulated by regarding the information value as a variation for the maximum opportunity loss of expectation from the aspect of decreased uncertainty in decision making. Furthermore, a consecutive information reference model and a route model considering information reference processes are presented; thus the case study was conducted using actual behavior data. As a result of the model estimation, we have found that the drivers who have higher uncertainty in decision making tend to have more opportunity to refer to the traffic information and that such uncertainty in decision making is considerably reduced upon the provision of multiple information sources.

This paper deals with the importance of ‘Driving Behavior models’ from the points of view of academic interests and engineering aspects. For academic interests, the mechanism of occurrence of capacity bottlenecks at basic freeway segments, which occur around sag sections or entrance of tunnels, should be clear. From the aspects of engineering, it is important to find countermeasures for such bottleneck phenomenon by traffic operation, road design, or future technology like Advanced cruise-assist Highway Systems. In this paper, reviewing the former driving behavior models, especially car-following behavior models, including man-machine model in the field of control theory, the future research needs for car-following models to analyzing bottleneck phenomena at basic freeway segments are summarized.

Under uncertainty, people do not necessarily behave stochastically, but behave based on rules and regulations which they form through their experiences. We formulated the route choice based on such inductive reasoning, and constructed the model of road transportation system. The aim of this study is to examine the behavior of road transportation system and route choice through simulation analysis. The results of the simulation, agents form “delusion” which means an extremely biased perception of the travel time, and habit which allow their behavior to be frozen. If the agents deliberate, the system nearly converges to user equilibrium; otherwise the system does not necessarily converge to it.

This research is to clarify of the image structure of landscape of Satochi which is the primitive image of landscape of Japanese on the basis of survey in Nishine-Town of Iwate prefecture. We did qualitative analysis of the meaning image, field image and visual image on the basis of investigation for inhabitants, movers and visitors of Nishine-Town of landscape of Satochi.
As a result, we have proved qualitative and objective data about the image structures of landscape and the point at issue of landscape of Satochi.

This study quantitatively evaluates effects of trip reservation systems that adjust departure times of travelers on motorways in a similar way to train seat reservations. A stated-preference survey was conducted at a service-area on a motorway. About 1, 500 survey sheets were distributed there, and about twenty percent of which were mailed back. Parameters of an logit-model that includes socio-economic, trip and trip-reservation related attributes of travelers were identified based on the SP survey. The effect of the trip-reservation on the mitigation of the traffic congestion is to be quantitatively evaluated by numerical simulation with the model and observed data on actual traffic congestion.

Mixed Logit model is developed recently as a strong tool which can approximate arbitrarily any random utility models. However, the flexibility and the applicability have not been well examined. This paper aims to clarify the attributes and summarize the relationship between the Mixed Logit model and other developed methods. We test its flexibility from the following aspects: 1) error structure among alternatives, 2) unobserved heterogeneity and 3) random coefficient model. Some simulation data or actual travel data are used for the model estimations. The results showed that the Mixed Logit model has high flexibility. Finally, we summarize its applicability and the further topics to be studied.

This paper describes about masonry technology of stone wall of Osaka Castle of Tokugawa period through the investigation on historical and empirical study. Firstly two collapse cases of stone wall, picking out through historical and literal and geotechnical study, were made clealy. And then, empirical and geotechnical approaches regarding on rationalism mechanics of masonry technology of stone wall were presented in the view point of shape of plane and cross section of stone wall. Moreover, in order to estimate the stability of stone wall structure, new engineering indexes, such as ratio of stone wall structure and deformation factor, were proposed.

The paper refers exclusively to the economic valuation of the attenuation of repairable physical risk caused by disaster through disaster prevention investment. A dynamic consumption model with disaster insurance systems is presented to investigate how a consumer's consumption behavior can be modified by the reduction of disaster risks. A simple cost-benefit calculation rule for disaster-proof investment is also presented to measure the long run effects of the disaster-proof investment upon a consumer's behavior.

Cost and time are esential parts of construction works accomplishment. According to the existing circumstances, construction works are analyzed under the deterministic or stochastic conditions. The deterministic conditions are assumed when random factors can be sufficiently eliminated. In opposite case the stochastic conditions must be considered. The requirements of construction works execution are described by using models of construction technology and resources. Scheduling of the works execution are realized by solving mixed linear programming problems under the requirement. In this paper, these are applied to cost-time scheduling of the small bridge erection as an example under stochastic conditions.
