Implementing The National Roads Telecommunications Services Project Technology Migration On A National Scale

摘要

This paper provides a high level outline of the Highways Agency's ("HA") "National Roads Telecommunications Services" ("NRTS") project to build a National telecommunications service for England's motorways. This paper is intended to share the experiences and the approach taken to developing and implementing this project and the lessons learned from migrating safety-related services to a new digital network with minimum loss of service. The project was developed into a 10? year PFI deal for a single national contractor to takeon, upgrade, operate and maintain the roadside telecommunications network on England's strategic roads. The contract was signed with GeneSYS on 16 September 2005, and is currently nearing the end of the 2 year initial implementation period. In this period GeneSYS will have taken-on all the existing services while upgrading and completing the backbone network to a fully digital network using generic components to replace the HA's aging bespoke equipment. During the implementation period GeneSYS have taken on the provision of services to support all of the existing signs, signals, emergency phones, inductive loop based incident detection systems (MIDAS) and CCTV cameras on the national network. GeneSYS have also migrated the majority of the existing services from the existing network to the new digital IP- based network without significant loss of service. At the same time the CCTV network has been converted to digital, providing a national switched CCTV network.
