Road vertical signs - Variable message traffic signs; German version EN 12966:2014
This European Standard is a product standard covering the requirements for variable message traffic signs (VMS). A VMS is a sign where the information shown can be changed or switched on or off as required. The information can be text and/or symbols. VMS fall into the two different types of continuous and discontinuous. Continuous VMS show sign faces of the types of fixed signs defined in EN 12899. Discontinuous VMS use luminous elements to show different messages on a single sign face. There is diversity of VMS. Some have elements that are placed with a view of displaying a few predetermined messages, while other have elements placed in arrays. Some can show messages where all elements have approximately the same luminous intensity while other can vary the luminous intensity individually. Some can show certain predetermined colours, while other can show a range of colours by means of the RGB technique. Some can show only character legends while other can show a wider range of legends. This European Standard uses requirements for performance of the characteristics, which are not dependent on technology. The visual and environmental performance is demonstrated on a test module. This European Standard contains a number of defined requirements, some of which have to be demonstrated on the test module, others that are to be verified by the manufacturer. It is the manufacturer's responsibility to ensure that the VMS is fully represented by the test module.
