Abstract
The research reported here is exploratory. Its purpose was to test the suitability for travel demand forecasting of a modelling approach known variously as "causal analysis", structural equations modelling", "path analysis", and "simultaneous equation systems". The application is to a general analysis of household mobility at the disaggregate level. The dependent variables in the proposed model include overall travel indicators such as total distances travelled by. different modes, total trips for different purposes, and car ownership.
