BS EN 50556:2018

Road traffic signal systems

Status : Current   Published : October 2018



This document specifies requirements for Road Traffic Signal Systems, including their development, design, testing, installation and maintenance. In particular, it forms the electrotechnical part of the following two standards issued by CEN: - EN 12368, Traffic control equipment - Signal heads; - EN 12675, Traffic signal controllers - Functional safety requirements. Each of these standards above will be used with this standard either singly or together to define an operational equipment or system. This will be achieved by using the electrotechnical methods and testing defined in this standard. Where Road Traffic Signal Systems are to be used with other systems, e.g. public lighting or railway signalling and communication, this document will be used with any other respective standard(s) for the other associated systems to ensure that overall safety is not compromised. This document is applicable to traffic signal control equipment permanently and temporarily installed, and portable traffic control equipment, with the exception of portable traffic signal equipment only capable of controlling alternate / shuttle working lanes (as further defined in 3.2.10).
