The first-generation signal and telephone systems, installed over a period of 15 years, now present a constraint in respect of meeting the competing demands for new and better replacement systems. The authors examine the potential for economically exploiting the remaining life of the first-generation signalling systems (NMCS1) on interurban sections by reducing the signal spacing to 1 km and adding automatic queue detection, and look at the design of microprocessor-based second generation national motorway communications systems (NMSC2) capable of operating, in addition to the basic provision of signals and telephones, a much wider range of individual and combined facilities.
