Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment her Department has made of the cost-benefit ratio of investing in traffic calming infrastructure compared to healthcare costs from road traffic accidents.

The Department for Transport has not made a specific assessment of the cost-benefit ratio of traffic calming infrastructure compared with healthcare costs arising from road traffic collisions.
