Travel survey data from two major metropolitan areas of Japan, taken at three time points spanning a period of 20 years, are analyzed and changes in travel characteristics and the spatial distributions of jobs and residences are examined. The two areas, the Kyoto-Osaka-Kobe (Kei-Han-Shin) metropolitan area and the Nagoya-Gifu (Chukyo) metropolitan area, developed along rail networks prior to the process of motorization began in the 1960's in Japan. Changes in travel characteristics in these two areas are examined using two sets of repeated cross-sectional data. The data cover the period from 1970 through 1990 in which these metropolitan areas experienced rapid growth and motorization. The analysis focuses on changes over time in mode use, commute trip length, daily travel time expenditure, and trip-chaining characteristics, and explores their associations with trip end location, residence and job locations, and other spatial factors. Changes in urban structure are inferred through the examination of the spatial distributions of job locations, residence locations, and activity locations. As a new indicator of urban structure, the spatial distribution of person-hours by activity type is proposed, and its effectiveness in portraying, along the time as well as spatial dimensions, the internal structure of an metropolitan area and the distribution of economic activities therein, is examined.

Sampling Alternatives from a Colossal Choice Set: an Application of the MCMC Algorithm 査読有り

It is often the case that a discrete choice model cannot be applied to forecasting because the choice set is unmanageably large and choice probabilities cannot be evaluated in a practical manner. For example, an activity-based analysis of travel behavior often involves an astronomical number of potential activity-travel patterns, resulting in an enormous choice set when one attempts to formulate the behavior as a discrete choice. A colossal choice set makes it practically impossible to define the full choice set and to evaluate the choice probability of each pattern for forecasting. This paper demonstrates an algorithm to simulate individuals' activity-travel choice by sampling activity-travel patterns from a colossal choice set according to their choice probabilities as determined by a discrete choice model, without enumerating the full choice set. Numerical examples are presented to demonstrate the practicality and effectiveness of the algorithm in forecasting the effects on activity-travel patterns of transportation policy measures.

An Analysis of Time Allocation, Departure Time and Route Choice Behaviour under Congestion Pricing 査読有り

Driver behavior under congestion pricing is analyzed in this study to evaluate the effects of alternative congestion pricing schemes. The analysis, which is based on stated-preference survey results, focuses on time allocation, departure time choice and route choice when a congestion pricing scheme is implemented on toll roads. A unique feature of the model system of this study is that departure time choice and route choice are analyzed in conjunction with the activities before and after the trip. A time allocation model is developed in this study to describe departure time choice, and a route and departure time choice model is developed as a multinomial logit model with alternatives representing the choice between freeways and surface streets and, for departure time, choice from among before, during, or after the period when congestion pricing is in effect. The results of the empirical analysis suggest that departing during the congestion pricing period tends to have higher utilities, and that a worker and a non-worker have quite different utility functions. The comparative analysis of different congestion pricing schemes is carried out based on the estimated parameters, and the results suggest that the probability of choosing each alternative is stable even if the length of the congestion pricing period changes, but that a higher congestion price causes more drivers to change the departure time to before the congestion pricing period.

世帯における自動車利用の競合を考慮した交通手段選択行動の分析査読有り Open Access

本研究では，世帯における自動車利用の競合を考慮することにより自動車利用の背反性を明示的に考慮した，世帯における交通手段選択モデルを構築した．すなわち，世帯が保有する自動車の配分問題として世帯構成員の交通手段選択行動をモデル化した．メインドライバーの選択を上位レベル，他の世帯構成員の選択を下位レベルとするネスティッド・ロジットモデルを適用し，スケールパラメータを構造化することにより世帯間のメインドライバーの自動車利用に対する優先度の異質性をモデルに導入し，モデル精度の向上を図った．実証分析の結果から，世帯における構成員間の相互作用を考慮することでモデルの推定精度の向上が確認された他，世帯主や普通乗用車のメインドライバーは他者の効用を考慮する傾向が弱いことが示された．
