DIN Standards Committee Building and Civil Engineering

Overview

The purpose of this European Standard is to define the functional safety requirements of the equipment used in control units for traffic signal controllers. This relates to the control of light signals for road traffic and all related signal-regulated traffic movements. The main concern is the protection of people and property against hazards caused by incompatible traffic signals. This European Standard specifies the functional safety requirements for traffic signal controllers. It 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 3.37), without the control of crossing vehicular or pedestrian movements. Traffic signal controllers, as defined by this European Standard, are required to control conflicting traffic, both vehicular and pedestrian in a safe manner. Examples are junction signals, pedestrian crossings, shuttle signals, public transport signals. The electrical safety requirements and additional traffic safety requirements, the interfacing with external equipment and the test methods for verifying compliance with this European Standard are contained in EN 50556. For a full applicability of this European Standard as well as of the EN 50556 the national standardization bodies are requested to define the set of classes relevant for their national requirements. The responsible committee for this standard is NA 005-10-24 GA "Gemeinschaftsarbeitsausschuss NABau/FGSV/FNL/FNF, Anlagen zur Verkehrssteuerung (SpA zu CEN/TC 226/WG 4)" "Joint working committee NABau/FNL/FNF: Traffic control installations (national mirror committee for CEN/TC 226/WG 4)") at DIN.
