Question to the Department for Transport:
To ask the Secretary of State for Transport, if the government has carried out a review of the effect of highway one way systems on congestion and pollution.
The Government has made no such assessment. Local authorities are responsible for the day to day management of their roads, including decisions on implementing traffic management measures such as one way systems. These are one measure available to them to consider but it is for them to consider if they are appropriate, taking into account local factors such as traffic flow and road layout.
