All local highway authorities around the M25 would have to jointly apply traffic management techniques with the Highways Agency, if the benefits of widening the M25 are to be ‘locked in’.
Transport secretary, Douglas Alexander, wrote to all the councils to ask them to start a dialogue with the agency in the autumn. A joined-up approach was ‘essential to find the best solutions’, likely to include making the most of available technology.
On the M25 itself, management would involve controlling motorway speeds and access on to the M25 at certain times, and using signals on some trunk and local authority roads to manage demand.
