HC Deb 19 February 1997 vol 290 c568W
Mr. Gordon Prentice

To ask the Secretary of State for Transport what criteria he uses to decide which lengths of motorway are lit. [16228]

Mr. Watts

I have asked the chief executive of the Highways Agency to write to the hon. Member.

Letter from Lawrie Haynes to Mr. Gordon Prentice, dated 19 February 1997: The Secretary of State for Transport has asked me to reply to your recent question asking what criteria he uses to decide which lengths of motorway are lit. The decision whether to light in a particular case is taken following consideration of a full appraisal of the proposed scheme. This includes an economic assessment of the capital, maintenance and energy costs set against the potential savings as a result of the reduction in night time personal injury accidents, calculated over the life of the lighting scheme. A full assessment of the environmental factors is taken into account.
