The purpose of transport models is to provide a tool to understand, and plan for, change. This may relate to changes in population, industry, technology, energy and climate.
Transport models must be fit for purpose. They need to be strategic and identify future transport needs. Updates to existing models should only be undertaken when there has been significant change on strategic context or future projections.
