SMART INTERSECTION LIGHTING
SMART INTERSECTION LIGHTING
DAGLASS company together with other members of the scientific and technical consortium, i.e. the Road and Bridge Research Institute (IBDiM), the Institute of Applied Optics. Prof. Maksymilian Pluta (INOS) and PODKOWA Sp. j. Boguszewscy, Perkowscy completed the project „Intelligent driver-friendly intersection – SPIK”. The project was carried out under the Applied Research Program No. PBS3/B6/29/2015.
As part of the above project, DAGLASS designed an optical system for illuminating a straight line and an arc, which was tested on a model intersection prepared at the IBDiM premises.
The systems for lighting a straight line and an arc have been correlated with existing classic vertical signals, i.e. they operate simultaneously, as shown in Photo. 1.

The optical system for illuminating a straight line was used as an additional red light signal in the form of a straight line, which is visible to the driver and informs early enough that it is impossible to enter the intersection (Photo 2).
Moreover, DAGLASS designed an optical system to illuminate the arc. The road curve is illuminated with green light, informing the driver about the possibility of entering the intersection via the designated route (Photo 3).
Photo 4 show example road situations at a model intersection with simultaneous use of arc lighting (green light) and straight line lighting (red light).

Innovative lighting for pedestrian crossings
DAGLASS optical system for lighting a straight line was used to illuminate a model pedestrian crossing located in the city of Rzeszów on Sikorskiego Street.
A specially designed lens system illuminates only the pedestrian crossing area, without illuminating the roadside or the area outside the crossing. The system turns on automatically after dark and illuminates the passage intermittently, i.e. the lighting is turned on and off cyclically. The effect obtained in this way, analogous to a flashing yellow light, acts as a warning to the driver who, when approaching the illuminated crossing, focuses his attention on the illuminated area, i.e. the pedestrian crossing. This significantly improves the safety of pedestrians using the illuminated crossing.
