    In order to promote a efficient utilization of local airport in Japan, an aircraftscheduling model for commuter services is discussed in this paper. The paper proposes a quadratic integer programming model and solved it by using the Hopfieldtype neural network algorithm which is expected to find out quasi optimal solutions. The validity, applicability, and tranferbility of the model was confirmed from a series of results. Moreover, several algolithms to get a better solution within realistic calculation time were proposed and tested.

  • CHARACTERISTIC OF PUBLIC ATTITUDES TO ROAD PRICING THROUGH A PACKAGE APPROACH

    Road Pricing is one of the most efficient policies to reduce traffic congestion and air pollution. This paper aims to clarify the characteristic of public attitudes to road pricing and the effect of gaining public support for road pricing through a package approach in the urban and suburban area of Osaka. The results shows that half of them supports for road pricing without a package approach. On the other hand, introducting the package approach that revenues gained from road pricing are used for the improvement of transportation services increases the ratio of public support to 75%. Road pricing has the enough acceptability among residents in the urban and suburban area of Osaka.

  • A DYNAMIC TRAFFIC SIMULATION MODEL CONSIDERING A ROUTE CHOICE BEHAVIOR ON ROAD NETWORK

    This paper proposes a dynamic traffic simulation model called BOX-MODEL for evaluating traffic control measures to reduce urban traffic congestion, for example Advanced Travelers Information Systems. This model simulates traffic condition in a large-scale network, and also simulates micro-scale traffic condition at intersections. Each link is divided into congestion-area and non-congestion-area. Each area is abstracted by some boxes whose size is identical to the the capacity per unit time of the area. This model simulates drivers' dynamic route choice. We examine the performance of the model through calculating dynamic traffic flow on an imaginary traffic network. The validity of the model is shown.

  • A RANDOM MATCHING MODEL FOR JOINT TRIPS PRODUCTION WITHIN HOUSEHOLDS
    Kiyoshi Kobayashi, Hideyuki Kita, Hirokazu Tatano

    This paper presents a random matching model for within-family joint trips production made by two family members. Our major concern is upon an explicit consideration of decision interactions between those who are involved in joint trips production. The random matching model has an advantage in incorporating psychological interactions based upon economic, altruistic, and paternalistic motives between joint-trip makers. The applicability of the proposed model is tested against the empirical data set.

  • UNCERTAINTY EVALUATION AND DELAY AVOIDANCE IN MODE CHOICE

    In examining the relation between the uncertainty evaluation and delay avoidance in modal choice, our aim is to solve three problems: 1. Formulating a delay avoidance model on the correlation between the travel time based on uncertainty evaluation and the arrival delay based on delay avoidance model; 2, the necessity of delay avoidance as a decisive factor in modal choice; 3. the empirical validity of uncertainty evaluation and delay avoidance. For this, we calibrate an improved disaggregate logit model on airport access trip data, and focus on our objectives comparing the results by AIC.

  • TREND AND CHARACTER OF THE MODERNIZATION OF BRIDGE ENGINEERING IN JAPAN
    A Study from a view point of structural comparison

    The trend and character of the Modernization of bridge engineering depended on how traditional pre-modern technology met the western modern technology just after the Meiji Revolution and how the western technology had been accepted since then. Aim of this study is to clarify the character and trend of Japanese modern bridge engineering through the investigation of traditional pre-modern bridge tecnology and modern bridge technology introduced from western countries at the most early age of Meiji.

    In order to decrease the track maintenance work on soil roadbed, an economical and reliable reinforced concrete roadbed was proposed for slab track. It has experimentally been laid at the site between Takasaki and Karuizawa of the Hokuriku Shinkansen line, and the static and dynamic loading tests on it have been carried out. Result confirmed that the fiber stresses and reinforced-bar stresses of the roadbed are on a low level from a point of view of durability, and that the settlement caused by the dynamic repeating load is extremely small.
