§ Mr. Peter Bruinvelsasked the Secretary of State for Transport if he will estimate the likely reduction in accidents that would occur on unlit sections of motorways if they were lit.
§ Mrs. ChalkerResearch results show the reduction in casualty accidents to be extremely variable. Further studies are in hand to try and improve the information.
§ Mr. Peter Bruinvelsasked the Secretary of State for Transport if he will estimate the cost of lighting (a) the remaining stretches of the M1 and (b) all other stretches of the motorway network.
§ Mrs. ChalkerThe estimated cost (at 1982–83 prices) of lighting the unlit lengths of the M1 and all other stretches of the motorway network are £9 million and £81 million respectively.
§ Mr. Peter Bruinvelsasked the Secretary of State for Transport when he expects the completion of lighting between the Newport Pagnell service centre and junction 16 of the M1; and whether he has any plans to provide additional lighting on the remaining unlit stretches of the M1.
§ Mrs. ChalkerThe installation of lighting on the M1 motorway between Newport Pagnell service area and junction 16 will be done in phases to accord with the programme for other roadworks and should be completed by spring 1987.
I am keeping under review the need to provide additional lighting on the remaining unlit stretches of the M1.
