AS 4852.1:2019 PDF Download

AS 4852.1:2019 is a standard that specifically focuses on fixed variable message signs (VMS). These signs are electrically powered and are used for traffic management and providing driver information. This standard, Part 1 of the series, covers fixed signs that are permanently mounted above or adjacent to the roadway, while Part 2 of the series covers portable signs that can be mounted on re-locatable trailers.

The standard lays out the requirements for the design, construction, performance, and installation of fixed VMS, including their control systems. It ensures that these signs meet the necessary criteria for their intended purposes and provides guidelines for their consistent implementation.

It's important to note that AS 4852.1:2019 does not cover certain types of message signs. For example, it excludes passenger information signs seen at bus stops or on train stations. It also excludes signs that are solely used for advertising products or services to road users. Additionally, signs that can only display a single message or a blank face are not within the scope of this standard.
