The estimated cost to the Highways Agency of hard shoulder running between Junctions 3a and 7 on the M42 is associated with the following four main areas of additional activity and cost.
Additional advanced motorway indicators over the hard shoulder—estimated cost of annual maintenance is £25,000.
Fixed CCTV cameras to monitor the hard shoulder—estimated costs of annual maintenance is £80,000.
Control room staff to open, close and monitor use of hard shoulder running—estimated annual cost is £38,000.
Additional traffic officer patrols to undertake pre-opening inspections of the hard shoulder and manage incidents—estimated annual cost of staff and vehicles is £66,000.
There are several additional areas for which it is not possible to disaggregate costs including power, sweeping and salting of the emergency refuge areas. These costs are considered to be negligible.
