SANRAL ITS Rehabilitation

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 length of the two networks is about 370km.

The projects use ITS technologies to manage traffic and provide road users with real-time traffic condition information.  This required TollInfra to perform a significant upgrade in bandwidth and complete the rehabilitation and replacement of existing fibre optic infrastructure.

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

SANRAL’s Head Office and Northern Region Office in Pretoria had to link into this backbone in order to provide for their corporate and operational requirements, which included:

  • Real-time voice-over-IP (VOIP);
  • Real-time video (streaming video-conferencing);
  • Business data (office applications, database connectivity and the SAP accounting platform)
  • Best effort data (internet, file transfer, e-mail);
  • Data exchange with the ORT systems;
  • Data exchange and live video feeds from the ITS Management Systems; and
  • Traffic data uploading onto the SANRAL system from traffic data loggers, which are located on 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.
