Transport modelling


Transport modelling is a way of predicting what will happen if we make efficient and effective changes to the road or transport network in the county.

For example, if we build a new:

  • bypass
  • housing estate
  • employment site

Transport models follow the government's Transport analysis guidance (TAG).

Why we use transport models

The models assist how new developments or highway improvements are reviewed through the analysis of:

  • traffic flows on particular highway links
  • link time especially to determine impacts of congestion
  • routing information
  • trips for any given year or scenario
  • mode, destination and time of day choice

We established the process to ensure that the development and appraisal of Transport Assessments are carried out in an efficient and effective manner.
