The National Roads Telecommunications Services is the fibre-optic network of communication and control used by National Highways to monitor England's roads. Its design has allowed for active traffic management and managed motorways in England.
History
Prior to 2005, the motorway network was controlled by the National Motorway Communication System (NMCS). This network was not fibre-optic or digitally controlled.
The £490 million contract for the NRTS was awarded to the GeneSYS Consortium on 19 September 2005. GeneSYS Consortium is a group of companies led by the Fluor Corporation and is a Public–private partnership.
The system is designed to allow a national scheme of road pricing, possibly using radio-frequency identification tags. The cost of the project was described by the Association of British Drivers as being "an awful lot to spend just for signs saying that motorways are closed and that you should not drink and drive."
In 2017, a second contract for the NRTS was awarded to Telent. Starting on 16 March 2018, the £450 million contract was set to run for 7 years, but was extended to run until 2027.
Structure
The NRTS is an intelligent transportation system based at the Quinton Business Park at Quinton, Birmingham. Video images are sent over fibre-optic cables to form a switched video network. The fibre-optic system was deployed with Guardian-Lite 3700 controllers, made by AMG Systems of Biggleswade, which allow uncompressed video signals and other data to be sent at the same time.
