Road lighting technical requirements
Regulations and standards define technical requirements related to lighting levels, uniformity of illumination and road classifications. These documents indicate that each road category requires an individual lighting design approach, covering both the main lighting scheme and transitional areas, as well as locations with a higher risk of accidents.
Modern requirements also take energy efficiency and compatibility with smart control systems into account. This allows lighting installations to be integrated into intelligent urban networks and supports more sustainable energy management practices.
Who is responsible for street lighting?
Responsibility for the condition and operation of street lighting generally lies with the owners or administrators of public roads. They are required to ensure compliance with applicable regulations and maintain safe conditions for road users.
In practice, this responsibility extends beyond the design and installation of lighting systems. It also includes regular maintenance, technical inspections and prompt response to failures that may affect road safety or user comfort. As a result, cooperation with experienced lighting manufacturers offering certified, standards-compliant solutions becomes an essential part of effective urban infrastructure management.
Regulations governing street lighting
While there is no single standalone law dedicated exclusively to street lighting, applicable requirements are primarily derived from transport regulations and road lighting standards. These documents define minimum illumination levels, lighting uniformity, road classes, locations requiring enhanced illumination, such as intersections, pedestrian crossings and tunnels, as well as energy performance criteria that support broader sustainability objectives.
The regulations also require lighting systems to be adapted to local environmental and weather conditions. In practice, this often means selecting light sources with a suitable colour temperature to maintain visibility and safety throughout the year.
Street lighting during winter
Winter conditions require special attention in both the design and operation of street lighting systems. Short daylight hours, fog, snowfall and rainfall can significantly reduce visibility and make road navigation more challenging.
In such conditions, maintaining adequate contrast and depth perception is essential, allowing drivers to react quickly and reducing the likelihood of accidents. This involves not only ensuring appropriate lighting levels, but also selecting the optimal colour temperature, which influences colour recognition, object perception and overall visual comfort. The right lighting solution can also help reduce glare caused by reflections from wet or snow-covered surfaces.
Streetlights: colour temperature and visibility in changing weather conditions
The choice of colour temperature has a significant impact on visibility during winter. Luminaires with a warmer light colour can improve visual perception in dense fog and during snowfall by reducing glare and enhancing contrast. Cooler light, on the other hand, can improve the visibility of fine details in clear conditions, but may increase reflections and visual discomfort on wet road surfaces.
For this reason, selecting the right lighting characteristics is a key aspect of modern street lighting design. Our experience in developing energy-efficient LED lighting systems enables us to offer solutions that combine high energy performance with flexible lighting control options. This approach makes it possible to adapt lighting conditions to the dynamic requirements of urban environments while maintaining safety, efficiency and user comfort.
