To ask the Secretary of State for Transport what measures his Department has taken to reduce noise volume for residents on the A3 trunk road in the region of Onslow village, Guildford; and if he will make on-site assessments of the noise level following the completion of recent works with particular reference to the effect of the laying of porous asphalt. [37574]

This is an operational matter for the Highways Agency. I have asked the chief executive to write to my right hon. Friend.

Letter from Lawrie Haynes to Mr. David Howell, dated 18 October 1995:

As you know, the Minister for Railways and Roads, Mr. John Watts, has asked me to write in reply to your Parliamentary Question asking what measures have been taken to reduce noise volume for residents on the A3 trunk road in the region of Onslow Village, Guildford; and if on-site assessments of the noise level will be made following the completion of recent works with particular reference to the effect of the laying of porous asphalt.
The Highways Agency has provided noise barriers and porous asphalt to limit noise levels from the A3 trunk road at the worst affected properties in the region of Onslow Village.
An evaluation to the effect of these noise measures has been carried out using the calculation procedures prescribed in the Noise Insulation Regulations. The calculation method is preferred because it applies a consistent technique for assessment which overcomes the many variables that affect noise over a period of time. The Agency has no proposals for carrying out on-site assessments.
