THE DEVELOPMENT OF ELASTICITIES FOR A ROAD PRICING MODEL

A key component of any transportation modelling exercise is the specification of suitable demand elasticities that define the relationship between a change in the cost of travel and demand. The paper describes a project carried out as part of the Department of Transport's Road Pricing (RP) Programme to develop a set of demand elasticities for a transport model that will be used in the assessment of various RP options in London. The work has been carried out by Halcrow Fox, Accent Marketing and Research and the Institute for Transport Studies, University of Leeds. The research was faced with the difficulty that relatively little formal evidence exists of motorists responses to an increase in the cost of travel as a result of the introduction of direct user charges. The paper provides an overview of the three main elements of research employed: (1) a literature review of existing evidence; (2) development of a theoretical framework for deducing elasticity values from first principles; and (3) a stated preference survey to obtain empirical values. All three elements were used in deriving a set of elasticities suitable for the assessment of a road pricing proposal. A particular feature of the work was the degree of disaggregation of the travel market for which values were required. Elasticities were specified by income group and journey purpose as well as by major modes. The paper concludes by summarising the elasticities developed. (A) For related work see IRRD 861094.
