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 orilluminance concept.
• Then applying, eg, time dependent
variables like traffic volume or weatherconditions, 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 underconsideration 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, orthere is change in geometry or parking areas –
luminance or illuminance)
•Pedestrian and low speed areas, P, ( for needsof pedestrians – illuminance, H and V)
