The results of Calculations According to CIE 30.2
In the (c;) system of coordinates, luminous intensities will be required at the
angular intervals stated below.
For all luminaires the angular intervals in elevation () should at most be 2.5
from 0° to 90° plus the permissible maximum field angle of elevation minus
the measurement angle of elevation, for the luminaire. In azimuth the
intervals can be varied according to the symmetry of the light distribution
from the luminaires as follows:
- Luminaires with no symmetry about c = 0° – 180° plane; the
intervals should at most be 5°, starting at 0°, when the luminaire is in
its measurement angle of elevation and ending at 355°.

Following statements take part in CIE 140 (page: 5);
I-table of road lighting luminaire with no symmetry light distribution
should be given according to those definitions.

The results of Calculations According to CIE 140
According to CIE 140, the observer’s eye height 1.5 m above road level, is
positioned transversely a quarter of road width from the carriageway edge,
and longitudinally at a distances in meters of 2.75 (mounting height: 1.5) in
front of the field of calculation.
In EN13201 Part: 3, it is stated that “the observer’s eye, is positioned in
the centre line of each lane in turn” by keeping all other parts same.
