SANRAL Communications Fibre Optic Backbone

SANRAL Head Office

The South African National Roads Agency Limited (SANRAL) had a requirement to establish a high bandwidth, high availability Fibre optic communications backbone for two major projects implemented along the main national routes in the Gauteng province. The combined lengths of the two networks are approximately 370km.

The first is an existing Intelligent Transportation System (ITS) project where ITS technologies are used to manage traffic and to provide road users with traffic conditions on a real-time basis. This project required a significant upgrade in bandwidth and the rehabilitation, and in some cases the replacement of, existing fibre optic infrastructure. The communications backbone must connect the Network Management Centre (NMC) to 27 Outstations where the video streams and data streams from approximately 240 field devices (the majority of which are cameras, but also include Variable Message Signs [VMS]) are collected for transfer to the NMC.

The second project is the Open Road Tolling (ORT) project implemented as part of the Gauteng Freeway Improvement Project (GFIP). The ORT project is an Electronic Toll Collection scheme designed to recover the investment on the GFIP infrastructure. It consists of 42 gantries with their associated Technical Shelters, 10 Satellite Centres (SC) for Customer Service, a separate redundant Operations Centre located at Dalpark, the Central Operations Centre (COC) located off Samrand Road in Midrand, and a Disaster Recovery Centre located at Rivonia.

SANRAL’s Head Office and Northern Region Office situated in Pretoria had to link into this backbone in order to provide for their Corporate and Operational requirements, which include:

  • Real-time voice (VOIP)
  • Real-time video (Streaming video-conferencing)
  • Business data (Office applications, database connectivity and SAP)
  • Best Effort data (Internet, File Transfer, E-mail)
  • Data exchange with the ORT system
  • Data exchange and live video feeds from the ITS Management Systems
  • Traffic data uploading on to the SANRAL system from traffic data loggers, which are located next to various motorways in the country.

The network is designed to facilitate later expansion, and to provide communications to SANRAL facilities from other provinces and third parties such as concessionaires.
