Some Developments in Transport Demand Modelling

This paper discusses some of the results obtained from the micro-economic interpretation of travel behaviour as it relates to the structuring of transport demand models. Emphasis is on evaluations using consumer surplus measures, and work done in Great Britain is mainly reported. The effects of variations in personal choice on the structure of demand models is analyzed, and the theory of personal difference models is developed. Some examples are given of a type of demand model (referred to as a "structured logit model") which is consistent with personal difference utility variation. /TRRL/
