Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will make an assessment of the potential impact of trends in the level of immigration on the road system.

The Department models future demand for road transport based on Office for National Statistics population forecasts, which include changes in population arising from immigration and other demographic change. Furthermore, the Department’s Common Analytical Scenarios consider futures that include high or low immigration to enable future uncertainty to be taken into account.
