SANRAL Communications Fibre Optic Backbone

The South African National Roads Agency Limited (SANRAL) implemented an Intelligent Transportation System (ITS) project to manage traffic and provide road users with real-time traffic condition information.  The ITS backbone connects the Network Management Centre (NMC) to 27 Outstations from where the video- and data streams from 240 field devices (cameras and Variable Message Signs [VMS]) are collected for transfer to the NMC.

This project has been operational for several years, and the duct infrastructure for the fibre optic cables has deteriorated significantly due to ongoing construction and repair of other services.

This project was further complicated by the reconstruction and expansion work SANRAL had commissioned on the Gauteng Freeway Improvement Project (GFIP).  Several highways were widened and most of the major interchanges were optimised and rebuilt.  Owing to the damage to duct infrastructure, Tollinfra had to rehabilitate and replace a significant portion of the backbone.
