The Department of Transport has provided communications facilities on 2,500 km of motorway to assist the police in the discharge of their responsibilities for traffic control and safe operation. The purpose of this paper is to describe how this situation is being tackled by the parallel actions of:- extending the useful economic remaining life of the existing first generation systems (NMCSI) on heavily used inter-urban sections by the provision (as an evaluatory trial, on 80 km of the Ml motorway) of closer spaced post mounted signals associated with automatic detection of queues and slow moving traffic; -introducing a new second generation of standard National Motorway Communications Systems (NMCS2) using micro-processor technology to make available a much wider range of facilities. These facilities will be exploited initially, to obtain greatest benefit on 180 km of the complex M25 London Orbital motorway. Thereafter the new systems will form the standard equipment for the gradual replacement of all the older systems as and when they reach the end of their useful economic life.
