South Australia's New Smart Expressway
The Department of Planning, Transport and Infrastructure (DPTI) has taken ownership of 14 BRAUMS/Swarco Variable Message Signs (VMS), all configured for the Australian public road network. These signs are currently being installed on the brand new 15 kilometre Northern Connector expressway in Adelaide, South Australia.

The signs consist of the following types:
- 6 x Small Type VMS
- 1 x Type-A VMS
- 4 x Type-B VMS
- 3 x Type-C VMS
Uninterrupted Communication to the Public
The extremely low-power attribute as standard of the BRAUMS/Swarco VMS has allowed BRAUMS and sister company Aldridge Traffic Controllers (ATC) to design, build and deliver Uninterruptible Power Supplies (UPS) to power each sign in its entirety, not just the VMS controller, guaranteeing an absolute minimum of four hours of operation in the event of loss of mains power to the site.

Initial testing of the largest sign (Type-C VMS) powered solely by the BRAUMS UPS demonstrated that the sign was left running for more than 12 hours, with no low battery voltage alarms raised after that period.

Full Colour Capability
Each sign uses the latest, state-of-the-art RGB LED and lensing technology to ensure that compliance to the high-level Australian Standard specification for photometric performance is both met and exceeded. The signs are to be managed by DPTI and communicate via the RMS Protocol to STREAMS. This configuration allows the VMS’ to drive messages in all colours currently supported by STREAMS, including Yellow, Blue, Red, White and Green.
