This document supersedes CEN/TR 13201-1:2004.
This revised publication includes a simplified system of guidelines for selection of the lighting classes. The most important parameters are listed for the different lighting situations - motorised traffic areas, conflict areas, and pedestrian/low speed areas. The parameters include the design speed, the traffic volume and traffic composition, the function of the overall layout of the road, and the environmental conditions.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Report: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. Introduction
This document offers guidance on the selection of lighting classes and related aspects. It is applicable to fixed lighting installations intended to provide good visibility to users of outdoor public traffic areas during the hours of darkness to support traffic safety, traffic flow and public security.
The document offers two alternative examples of selection of lighting classes, one based on simple lighting class and the other giving a more refined result within the lighting class. Both methods provide comparable lighting classes and are interchangeable. Any adaptation of either of these methods or any other method can be used instead, on the national level. 1 Scope
This Technical Report specifies the lighting classes set out in EN 13201-2 and gives guidelines on the selection of the most appropriate class for a given situation. To do this, it includes a system to define appropriate lighting classes for different outdoor public areas in terms of parameters relevant to guarantee the aims presented in introductions.
The decision on whether a road should be lit is defined in the national road lighting policy. This varies by country or municipality. Specific guidelines are usually available at national level for each country. This Technical Report does not give the criteria on which a decision to light an area can be made, nor on how a lighting installation should be used. Further guidance is given in CIE 115:2010 (Paragraph 1.2 and Annex A).
The methods presented in Clauses 5, 6 and 7 have to be considered as the starting points of a comprehensive approach for the normal road lighting. In that sense, the models cannot cover all the different road cases; they introduce general parameters and the impact on lighting requirements. Only the real situation and its unique characteristics (geometry of the road, marking, visual environment, difficulty of the navigation task, lack of visibility, risks of glares due to existing elements, local weather, specific users such as high rate of elderly or visually impaired people, etc.) can lead to a final determination of the appropriate lighting class applying risk evaluation techniques.
The visual needs of road users under reduced traffic volumes during certain periods of night or under varying weather conditions, and the positive benefits of reduced energy consumption and potential environmental improvements, are some of the considerations which justify the installation of adaptive road lighting. There are a variety of suitable instruments, devices and methods which can be used for the intelligent control of a road lighting installation. The control systems range from very simple to the most sophisticated applications. Annex Renewal or refurbishment of obsolete and uneconomic installations is important. It may be possible to obtain more adapted lighting levels with lower energy consumption using new designs and new technology. The upgrading of lighting and control systems will often give good cost-benefit ratios and short amortisation periods.
This document does not give guidelines on the selection of lighting classes for toll stations, tunnels or canals and locks.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13201-2 and EN 13201-3 and the following apply.
3.1
normal lighting class
class with the maximum value of average luminance or illuminance at any period of operation
3.2
adaptive lighting
temporal controlled changes in luminance or illuminance in relation to traffic volume, time, weather or other parameters
3.3
motorised traffic (M)
motor powered vehicles
3.4
conflict area (C)
relevant area where motorised traffic streams intersect each other or overlap areas frequented by other user types
3.5
pedestrians and low speed area (P)
relevant area reserved for use by people on foot or using bicycle, and drivers of motorised vehicles at low speed (< 40 km/h)
3.6
design speed
speed selected for purposes of design and correlation of the geometric features of a road and is a measure of the quality of design offered by the road
Note 1 to entry. It is the highest continuous speed at which individual vehicles can travel with safety on a road when weather conditions are favourable and traffic density is so low that the safe speed is determined by the geometric features of the road.
3.7
traffic volume
the number of vehicles passing a given point in a stated time period in both directions
Note 1 to entry: E g. average daily traffic is measured as number of vehicles per day.
3.8
maximum capacity
maximum rate of flow at which vehicles can be reasonably expected to traverse a point or uniform segment of a lane or carriageway during a specified time period under prevailing road, traffic and control conditions
Note 1 to entry: Usually expressed as veh/h or veh/d.
3.9
traffic density
number of vehicles occupying a given length of lane or carriageway averaged over time
Note 1 to entry: Usually expressed as veh/km or veh/km/lane.
3.10
traffic composition
distribution of vehicle types in the traffic stream, directional distribution of traffic, lane use distribution of traffic, and type of driver population on a given facility
Note 1 to entry: In this report simplified: mixed and motorised only.
3.11
junction
place where several traffic routes meet, join, or cross each other, and a location where traffic can change between different routes
3.12
intersection
general area where two or more roads join or cross at the same level, within which are included the carriageway and roadside facilities for traffic movements
3.13
interchange
grade-separated junction with one or more turning ramps for travel between the through roads
3.14
ambient luminosity
assessed luminance levels of the surroundings
3.15
visual guidance / traffic control
means that ensure that motorists are given adequate information on the course of the road
3.16
facial recognition
visual task of pedest
