高密度都市圏での交通エネルギー消費削減に向けた土地利用政策の有効性査読有り

北村隆一，山本俊行，神尾亮

土木学会論文集 ( 625/IV-44 ) 頁： 171-180 1999年

記述言語：日本語掲載種別：研究論文（学術雑誌）

本研究では世帯の交通エネルギ－消費量，通勤交通機関，自動車保有台数，通勤距離を内生変数とする構造方程式モデルを1990年京阪神パーソン・トリップ調査結果を用いて推定し，世帯の交通エネルギ－消費性向に考察を加えると同時に，このモデルを土地利用政策のエネルギ－消費削減効果の分析に適用している．モデルの推定結果は，より高密度で職住近接型の土地利用を推進することにより世帯の交通エネルギ－消費を削減することが可能であることを示唆している．しかしながら，既に高密度・混在型の土地利用が展開し自動車利用率が比較的低い京阪神都市圏で世帯交通エネルギ－消費の大幅な削減を図るとすれば，都市圏外延部に居住し長距離通勤を行う世帯を対象とする土地利用政策が必要となることを本研究の結果は示唆している．

Vehicle Ownership Model That Incorporates the Causal Structure Underlying Attitudes Toward Vehicle Ownership 査読有り

Household vehicle ownership behavior is governed by not only economic considerations but also psychological and sociological factors. The latter factors are expected to play important roles in earlier stages of motorization. Previous disaggregate models of household vehicle ownership behavior, however, have been developed mostly for countries with mature motorization and most often have included only economic factors as explanatory variables that determine the utility of a household vehicle. These models are limited as models of vehicle ownership behavior in earlier stages of motorization if psychological and sociological factors are in fact significant determinants of household vehicle ownership decision. Considered in this study is the concept of “Symbolic Utility" of vehicle ownership, which refers to psychological satisfaction from owning and using a vehicle. Based on analyses of the causal structure among attitudes towards vehicle ownership, a vehicle ownership model system is developed in the study. The results of this study suggest that attitudes towards vehicle ownership have effects on vehicle ownership preference, and the accuracy of vehicle ownership choice models can be improved by taking symbolic utility into consideration. The results of the model estimation also indicate the presence of cognitive dissonance of non-owner households and “Veblen effects" of vehicle ownership.

Competing-Risks-Duration Model of Household Vehicle Transactions with Indicators of Changes in Explanatory Variables 査読有り

in this study. The model is developed assuming the following three types of competing risks: replacing one of the vehicles in the household fleet, disposing of one vehicle in the fleet, and acquiring one vehicle to add to the fleet. In addition to the attributes of household, changes in household attributes are expected to have strong effects on vehicle transactions behavior. To account for their effects, dummy variables indicating the occurrence of a change in selected household attributes are defined as time varying covariates and introduced into the model. In addition, vehicle transactions themselves change the needs and motivations for vehicles holding, affecting the timing and the type of the transaction that immediately follows. Dummy variables indicating the type of the preceding transaction are also introduced as time varying covariates into the model. The results of the empirical analysis using a data set collected in a panel survey empirically support the theoretical considerations underlying the model development, and indicate that the effects of changes in household attributes and that of a preceding transaction are well represented in the model.

An Analysis of Time Allocation to In-home and Out-of-home Discretionary Activities across Working Days and Non-working Days 査読有り

The behavior of time allocation to two types of discretionary activities is formulated as a doubly-censored Tobit model. The model is capable of incorporating cases where the entire amount of time available for discretionary activity is allocated to one type of activity and the other type of activity is not engaged at all. The model is applied to examine individuals' allocation of time to in-home and out-of-home discretionary activities on working days and non-working days, using a weekly time-use data set from the Netherlands. Workers' daily activity patterns vary significantly between working days and non-working days, while it can be expected that patterns of time allocation are correlated between working days and non-working days. A set of error components is introduced into the model to represent this correlation, adopting a mass point approach which requires no assumption about the distribution of the error components. The validity of the model is examined statistically.
