Final Report Lot 9: Public street lighting - Amper

1.1.2 Performance requirements and street lighting categories
Performance requirements for new street lighting installations are drawn up by CEN TC
169/226 JWG in standard EN 13201-2. Note that in the installed base or stock of street lighting,
older equipment do not necessarily meet these relatively new performance requirements e.g.
lighting level, uniformity etc.. Determination of real-life performance versus standard
performance is part of this study (chapter 3).
Guideline CEN/TR 13201-1 specifies the selection of lighting classes for road lighting. This
guideline considers the lighting classes set out in EN 13201-2 and provides guidance on the
application of these classes. To do this, it includes a system to define an outdoor public traffic
area in terms of parameters relevant to lighting. To assist in the application of classes, it
suggests a practical relationship between the various series of lighting classes, in terms of
comparable or alternative classes.
The standard EN 13201-2 contains performance requirements in defined classes (ME1..ME6,
MEW1..MEW6, CE0..CE5, S1..S6, ES1 .. ES6, A1 .. A6 ). A lighting class is characterized by
a set of photometric requirements aiming at the visual needs of certain road users in certain
types of road areas and environment.
Because the number of classes specified in the standard is relatively extensive, a simplified and
more aggregated classification of 3 road categories (see figure 8) is followed in this study..
These categories with the same lighting levels and more corresponding with the classes used in
European statistics for road lengths are defined hereafter:
1. Category F “fast traffic” with fast motorized traffic use only, having only luminance
requirements (cd/m²). Also corresponding to classes ME1 to ME5 or MEW1 to MEW5 for
new installations.
2. Category M “mixed traffic” with motorized traffic, slow moving vehicles, and possibly
cyclists and pedestrians with only luminance requirements (cd/m² ). Also corresponding to
classes ME2 to ME5 or MEW2 to MEW5 for new installations.
3. Category S “slow traffic” for mainly urban and pedestrian areas, with illuminance
requirements only (lx). Corresponding to classes CE0 to CE5, S1 to S6 and ES, EV and A
classes for new installations.
