Road Lighting

• TC 4-48 White Light in Road Lighting



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)
