Evaluation of trip-inducing effects of new freeways using a structural equations model system of commuters' time use and travel

摘要

A structural equations model system which represents the effects of transportation control measures on commuters' daily activity patterns after work hours is presented. A commuter's daily activity after work till going to sleep is defined in terms of variables that indicate time use and travel. These variables are the endogenous variables of the structural equations model system. The parameters of the model system are estimated using one-day activity diary data collected in 1994 in the Osaka-Kobe metropolitan area. The model system is applied to evaluate the impacts of hypothetical freeway lines in the Osaka-Kobe metro- politan area upon area residents' time use and travel.
