CIE 115:2008
• Lighting of Roads for Motor and Pedestrian Traffic
• Since CIE 115:1995, power consumption and
environmental aspects have become important. There have
been improvements in performance of lamps, luminaires
and electronic control gear.
• Now possible to introduce adaptive lighting for roads with
motorised traffic (M), conflict areas ( C) and pedestrian
traffic (P)
CIE 115:2008
• A structured model is developed for the
selection of the appropriate lighting
categories based on the luminance or
illuminance concept.
• Then applying, eg, time dependent
variables like traffic volume or weather
conditions, the model offers the possibility
of using an adaptive system
Criteria for Road Lighting
• Roads for motor traffic – Luminance
• Conflict areas – Luminance/illuminance
concept (Eh)
• Pedestrian areas – illuminance concept (Eh
and Ev and Esc)
Criteria for Road Lighting
• Conflict Areas:
• When vehicle streams intersect each other
or with pedestrians, cyclists or others.
• Change in road geometry.
• Parking areas, toll stations
Lighting Classes
• Normal Lighting:
• That lighting category which is appropriate if the
same level is to be used throughout the hours of
darkness.
• Adaptive Lighting:
• Temporal changes in parameters under
consideration when selecting Normal class could
allow relaxation of Normal levels.
Lighting Areas
• Motorised traffic, M, (for drivers of motorised
vehicles – luminance)
• Conflict areas, C, (where traffic streams
intersect, or run into areas with peds. cyclists, or
there is change in geometry or parking areas –
luminance or illuminance)
• Pedestrian and low speed areas, P, ( for needs
of pedestrians – illuminance, H and V)

Summary
• Proposes model for Adaptive Lighting
• Weight important parameters for each time
period
• Sum of the Weighting Values is related to
the Lighting category
• Only the quantitative variables change, the
qualitative variables stay at the appropriate
Normal lighting levels
