The question

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.

Answered by Simon Lightwood

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. Decisions on the provision of traffic calming measures are a matter for local highway authorities, which are responsible for managing their road networks and assessing local needs and priorities.
