CEN/TC 226/WG 4 - Traffic control

This document applies to signal heads with one or more signal lights of the colours red, yellow and/or green signal lights for road traffic with 200 mm and 300 mm roundels and to optical units to be integrated in signal heads to produce the individual signal lights. It defines the product characteristics for the visual, structural, environmental performances and testing of signal heads and optical units for pedestrian and road traffic use, and the rules for the evaluation of the conformity of these products.
This document can be partly or fully applied on a voluntary basis to other signal heads outside of the scope specified above like for instance white optical units or small signal heads with a diameter smaller than 200 mm.

This European Standard specifies the functional safety requirements for traffic signal controllers. It is applicable to traffic signal control equipment permanent¬ly and temporarily installed, but excludes portable traffic control equip¬ment. Traffic signal controllers, as defined by this European Standard, are required to control conflicting traffic, both vehicular and pedestrian,  e.g. junction signals, pedestrian crossings, shuttle signals, public transport signals, in a safe manner.  
The electrical safety requirements and additional traffic safety requirements, the interfacing with external equip¬ment and the test methods for verifying compliance with this European Standard are contained in HD 638.
NOTE  National requirements may specify special conditions for public transport signals (PT) and for any other signal that is not specified in a European Standard.

This European Standard specifies the requirements for individual electrically operated light devices, called warning lights, emitting a continuous or regular intermittent light of a single colour which, by their colour and position alone, are used to warn, inform or guide road users. It specifies the requirements for visual, structural and operational performances and the relevant test methods to be used. These devices rely upon existing furniture to provide the mounting.
This European Standard is not applicable to lighting devices which convey messages by additional means (e.g. variable message signs) or which convey a mandatory instruction (e.g. traffic signals) or which are covered by vehicle lighting regulations.
This European Standard does not consider horizontal loads because it is the mounting to which they are fixed, which is not covered by this European Standard, which has to resist applied horizontal loads.

This standard defines the functional safety requirements of traffic signal control equipment. The electrical safety requirements, conditions of failure, interfacing with external equipment, and functional test methods are contained in (reference No of the parallel CENELEC document). This standard covers the functional safety requirements, of traffic signals control equipment permanently and temporarily installed, but excluding portable traffic control equipment.

This European Standard only applies to red, yellow and green signal lights for road traffic with 200 mm and 300 mm roundels. It defines the requirements for the visual, structural, environmental performances and testing of signal heads for pedestrian and road traffic use. Portable signal lights are specifically excluded from the scope of this European Standard.

This European Prestandard specifies the requirements for detectors used in traffic systems to control road vehicles using traffic signals. It specifies these requirements in function only. The performance requirements apply where detectors, whatever the technology used, provide the sensing zone, together with the processing needed to derive the required output. A special case exists for loop detectors where the loop layout determines the sensing zone in part. This European Prestandard is applicable to detectors which operate by passive detection. It is not applicable to guided vehicles (trams).
