§ Mr. Gordon PrenticeTo ask the Secretary of State for Transport what criteria are used to justify the addition or the removal of towns and cities from motorway direction signs.
§ Mr. WattsThe main criteria are traffic importance, the requirement to maintain continuity of signing for long-distance traffic, and the number of destinations that can be read by drivers in the time available. The principles of directional signing are explained in "The Design and Use of Directional Informatory Signs"—Local Transport Note 1/94—published by HMSO.
