Street and Avenue Lighting

It is necessary to ensure that drivers travel safely and to ensure the safety of pedestrians by increasing their visibility. To ensure this, the needs of the driver must be taken into account and visual conditions must be improved.

The lighting designs of boulevards, avenues, alleys, intersections, walking/cycling paths and pedestrian crossings in residential areas must comply with international standards without causing light pollution.

In road illumination calculations, road average luminance (L0), average evenness (U0), longitudinal evenness (U1), relative threshold increment (TI) and surrounding ratio (SR) are important parameters.
Glare in road lighting is also extremely important. Direct glare from the lighting fixture causes losses in visual performance. Glare will reduce the visibility of dangerous objects on the road.

Design calculations must be made to ensure the correct selection of road lighting classes and the required parameter values.

The number and type of luminaires should be determined according to these calculations, and it should be ensured that lighting is used as much as necessary when necessary, with installations with light level sensors and time control.
