Project: Review of MVA's Research into Improved Elasticity

Reference: H037A1

Last update: 19/11/2003 16:24:35


The aim of this project was to refine the elasticity values and models, as well as review the theoretical approaches to elasticity.


This research was commissioned to complement the Guidance on Induced Traffic produced in December 1994 (Volume 12.2.2 of the Design Manual for Roads and Bridges).

Summary of results

  1. The project concluded that the range of elasticity demand functions could be extended, but that the elasticity value chosen could be crucial to the modelled results. Choice models such as logit functions ought to generate responses which take account of cross-commodity effects better than simple elasticity functions. This sub-project reviewed the above findings and other technical findings as reported in MVA's final report.

Departmental Assessment Status: Project completed prior to the implementation of the Departmental publications scheme.
