SA TS 5719:2017 PDF Download

SA TS 5719:2017 is a communications protocol standard that specifically focuses on the interaction between various systems used in dynamic message signs (DMS) and road weather information systems (RWIS). The standard defines the physical means and protocols required for effective communication with these systems.

The Technical Specification provides guidance on the communication protocols to be used, ensuring seamless and efficient data exchange between the DMS and RWIS. It also outlines the necessary functionality for implementing these protocols. The standard covers a wide range of DMS, including variable message signs (VMS), changeable message signs (CMS), electronic speed limit signs (ESLS), lane use signs (LUS), and school zone alert signs (SZAS).

Additionally, the communication protocol described in this standard supports the display of travel times on VMS, further enhancing the functionality and capabilities of these systems.
