LUMINANCE: Position of calculation points Spacing of the points in a driving lane :

In the longitudinal direction : D = S / N

In the transverse direction : d = WL / 3

D : spacing between points in the longitudinal direction, in metres

d : spacing between points in the tranverse direction, in metres

S : spacing between luminaires in the same row, in metres

WL : width of the lane, in metres

N : number of calculation points in the longitudinal direction with the following values:

The outermost calculation points are spaced d/2 from the edges of the lane.

for S ≤ 30 m, N = 10; for S > 30 m, the smallest integer giving D ≤ 3 m The first transverse row of calculation points is spaced at a distance D/2 beyond the first luminaire (remote from the observer).

17

Surround ratio: SR The width of all four strips shall be the same, and equal to 5 m, or half the width of the carriageway.

Location of strips with width of strip equals 5 m : 6

SR(1) = E1/E2

SR(2) = E4/E3

SR = (E1+E4) / (E2+E3)

CIE 115

EN 13201

For dual carriageways, both carriageways together are treated as a single carriageway unless they are separated by more than 10 m.

18

Surround ratio: SR The width of all four strips shall be the same, and equal to 5 m, or half the width of the carriageway.

Location of strips with width of strip less than 5 m because width of carriageway is less than 10 m

SR = (E1+E4) / (E2+E3)
