M42 hard shoulder running saves lives

Up to nine people are still alive thanks to the pilot Active Traffic Management (ATM) system which opened on a stretch of the M42 almost three years ago, NCE understands.

Accidents were increasing on that stretch of road, and forecasts would suggest that around three people would lose their lives along the stretch of motorway between junctions 3A and 7 of the M42.

ATM allows motorway traffic to use hard shoulders at busy times.

Since the M42 scheme opened on 12 September 2006, no lives have been lost in the three years of operation.

Cutting journey times and emissions

Hard shoulder running kicks in when sensor loops in the carriageway tell a central control centre when the road is becoming congested.

The central traffic control centre can open the hard shoulder to traffic but at a reduced speed − usually 50mph or 60mph, using gantry mounted variable speed limit signs. Journey times and emissions have fallen in the pilot scheme, which is now being rolled out on further motorways (NCE 22 January).
