§ Mr. Nicholas Wintertonasked the Secretary of State for Transport to what extent his Department uses equipment for the automatic monitoring of the usage of motorways by type of vehicle; and if he will publish the overall results of such monitoring in the Official Report.
§ Mr. Kenneth ClarkeThe counting of traffic by type of vehicle is at present undertaken by local government employees. However, arrangements are being made to replace the regular counting for the Department's core census of traffic by automatic monitoring using equipment that will classify vehicles by type. This will involve about 25 automatic sites on motorways.
Full details of the Regular monitoring of traffic are published annually in "Transport Statistics Great Britain", which is available in the Library.
