When Trantek MST needed a reliable rebroadcast system for the Sydney Harbour Tunnel intelligent transport system upgrade project, they chose RFI.

The AM/FM radio rebroadcast system is a relatively minor, but vital, component of the overall total intelligent transport system not only to maintain the rebroadcast of AM and FM radio stations within the Tunnel, but also to ensure that vital incident management capabilities can be maintained In the event off a sub-system failure. An audio break-in capability allows pre-recorded or live audio announcements to be inserted into the AM and FM rebroadcasts to notify drivers of incident information via their car radios. Trantek MST sought a partner who could design, install and commission the rebroadcast system upgrade as a turnkey sub-contractor.

“We chose RFI because of their proven technical, manufacturing, installation and integration capabilities. RFI has proven extremely easy to work with, quickly understanding the technical requirements of Trantek MST’s fault resilient architecture and integrating and where necessary manufacturing custom components to achieve a truly satisfying solution.” said Trantek MST Managing Director, Mr Lionel Ascone. “They have provided the Sydney Harbour Tunnel with an upgraded rebroadcast system that has met the customer’s operational requirements, whilst also providing a feature-rich capability that allowed us to incorporate it into our fault-resilient intelligent transport control system.” “RFI performed well within the often challenging multi-disciplined environment that exists in a major project, and has delivered their system to the project on-budget – assisting Trantek MST to deliver another successful project to its customers.”

Trantek MST was tasked with the design and installation of an upgrade to the Sydney Harbour Tunnel intelligent transport system in NSW, Australia. The Sydney Harbour Tunnel is one of Sydney’s primary transport routes, with busy vehicular traffic using the tunnel 24 hours a day, 7 days a week. As well as meeting the stringent operational requirements, Trantek MST needed a partner with the experience to handle the challenges of working on one of Sydney’s busiest roadways. Trantek MST selected RFI to provide the rebroadcast system, based on RFI’s experience and expertise with this technology.
