Intersection Lighting 5 ways to improve
Currently, many intersections lack sufficient lighting, which can compromise road safety. Factors such as limited budgets, outdated technology, and lack of awareness of lighting's critical role in traffic safety often contribute to this issue. Additionally, many existing lighting systems rely on older, less effective technology that results in dim or uneven lighting.
High-quality intersection lighting provides the following benefits:
Increased Visibility. High-quality lighting at intersections enhances visibility for both drivers and pedestrians, especially at night and during adverse weather. Effective lighting illuminates the entire intersection, reducing shadows and providing even light coverage, which helps prevent accidents. European lighting standards set specific guidelines for optimal brightness levels to ensure that intersections are well-lit, without causing glare or light scatter.
Energy Efficiency and Cost Savings. Using the latest LED lighting solutions at intersections not only provides better illumination but also reduces energy consumption and maintenance costs. For instance, a lot of large cities have adopted smart LED lighting that automatically adjusts brightness based on traffic levels and time of day, which cuts down on energy costs. These new technologies also last longer, requiring less maintenance over time.
Reduced Light Pollution. Modern intersection lighting is designed to minimize light pollution, which is beneficial for the environment and nearby residential areas. By using focused optical lenses to direct light to targeted areas, cities can reduce unwanted light spillage.
Crime Prevention. Well-lit intersections also contribute to crime prevention by creating a safer environment. Studies have shown that illuminated areas are less prone to crime, as they deter criminal activity. For instance, in some European capitals, many intersections have been upgraded with brighter lights, leading to improved public safety and lower crime rates in these areas.
Compliance with European Standards. European standards like EN 13201 provide comprehensive requirements for intersection lighting, including brightness levels and uniformity to ensure adequate lighting for all users. By adhering to these standards, cities can improve safety and efficiency while maintaining consistency across different regions.
Several European cities already demonstrate effective intersection lighting. For example, in Oslo, Norway, the Bjørvika Tunnel entrance (see below pictures) uses LED lighting that adjusts with the natural light levels, ensuring consistent visibility. Similarly, the Place Charles de Gaulle in Paris employs directional LED lighting to guide vehicles and pedestrians without causing glare, highlighting the benefits of focused lighting in complex intersections.
High-quality lighting at intersections is essential
High-quality lighting at intersections is essential for public safety and the livability of urban spaces. Effective lighting reduces accidents, deters crime, and enhances the general quality of life by making public spaces feel safer and more welcoming. Upgrading old lighting systems and adhering to established standards are vital steps toward sustainable, resilient urban infrastructure.
Nowadays local municipalities have a few effective options to modernize their intersection lighting affordably:
Adding extra brackets with lamps to current poles is an effective way to increase lighting coverage without installing new poles. This approach allows for targeted lighting in areas that need additional illumination, like crosswalks or areas with high traffic, ensuring a more comprehensive and uniform light distribution. This solution also minimizes installation costs and the need for new infrastructure.
Replacing older lamps with LEDs on existing poles is another effective upgrade. LED lights are energy-efficient, long-lasting, and offer improved brightness and uniformity, which significantly enhances visibility and safety. This switch reduces energy costs and maintenance needs, as LEDs typically last longer than traditional lighting.
Implementing smart lighting controls. Smart systems can dim or brighten lights based on time of day, traffic flow, or weather conditions. This dynamic approach optimizes energy use and provides maximum lighting when it’s needed most, ensuring a more adaptive and responsive lighting system.
These strategies can help to modernize their intersection lighting with minimal disruption and cost, creating safer, more sustainable urban environments. By adopting these upgrades, cities can extend the life of their lighting infrastructure while aligning with modern standards for safety, efficiency, and environmental impact.
