Variable Speed Limit Signs are electronic illuminated traffic signs emulating the static version of the conventional Speed Limit Regulatory Sign R4-1 with the capacity to set any value speed limit and also display other graphical symbols. VSLS’s are generally controlled from a TMCC (traffic management control centre) and are designed to operate either in single mode or groups. Communications protocol is RTA Communications protocol for roadside devices TSI-SP-003.
Manufactured to meet strict optical and environmental standards Compusign’s VSLS’s are currently in operation in some of Australia’s most prestigious ITS Projects.
Simple to Integrate, and easy to maintain our VSLS come with RTA compliant maintenance software.
Reliability, functionality and visibility have been the driving elements in the design of all VSLS components. VSLS are ideal for areas requiring a variety of speed limits implemented in order to control the constantly changing road conditions such as Toll ways, worksites, tunnels and Speed Camera Detection systems.
