Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the potential impact of traffic congestion on the economy.

The Department for Transport publishes transport analysis guidance to help assess the economic cost of congestion associated with different policy interventions. It also regularly publishes statistics on speeds, delay and reliability on different types of roads. However, it does not routinely assess the economic cost of congestion on the road network as a whole.
