Road lighting to EN 13201, right the first time

Road lighting is governed by the European EN 13201 series. It defines lighting classes based on road type, speed and traffic, and the photometric values each class must meet. Public projects and tenders require this compliance to be proven by calculation.

In DIALux Evo we model the exact road geometry — carriageway and footway widths, pole spacing, mounting height, overhang and tilt — and verify every EN 13201 parameter: average luminance (L̄), overall uniformity (Uo), longitudinal uniformity (Ul), threshold increment (fTI) and edge illuminance ratio (REI).

We also report energy performance to EN 13201-5 — the power density indicator (PDI) and annual energy consumption indicator (AECI) — and check upward light against the light-pollution rules of the project.

EN 13201-2 — Main lighting classes

M1 (motorway, high speed): L̄ 2.00 cd/m²
M2 (main national road): L̄ 1.50 cd/m²
M3 (distributor road): L̄ 1.00 cd/m²
M4 (main local street): L̄ 0.75 cd/m²
M5 (residential road): L̄ 0.50 cd/m²
M6 (low-traffic road): L̄ 0.30 cd/m²
C0–C5 (intersections, roundabouts): Ē 50–7.5 lx
P1–P6 (pedestrian areas, cycle paths): Ē 15–2 lx

frequently asked questions

Questions about road lighting

Which EN 13201 class applies to a town street?

Roads with motor traffic use M classes, chosen by speed, traffic volume and road function: typically M3–M4 for distributor and main local streets, M5–M6 for residential roads. Low-speed residential and pedestrian streets often use P classes. The class follows CEN/TR 13201-1; in Romania it is usually set in the tender documents, in line with NP 062.

What is the difference between luminance and illuminance calculations?

Luminance (M classes) takes into account the road surface reflection and the driver’s viewpoint, and is the method EN 13201 uses for roads with motor traffic. Illuminance (C and P classes) is used for conflict areas, pedestrian zones and low-speed streets.

What mounting height should the luminaires have?

It depends on road width and the luminaire’s optic. As a rule of thumb, 6–8 m poles suit 6–8 m wide streets and 8–10 m poles suit roads 10–12 m wide. The calculation sets the exact height and spacing.

Can you work on road projects outside Romania?

Yes. EN 13201 applies across Europe. Tell us the national requirements of the project country — class selection rules, light-pollution limits — and we design to them.

How long does a study take?

For standard road sections up to about 500 m, 24–48 hours. Projects with intersections, roundabouts or several pedestrian areas take 48–72 hours. The exact deadline comes with the quote.
