Abstract [en]

Road lighting causes unwanted ecological impact on species and habitats where species may be protected and/or light-sensitive. Yet, there is very little information available on how roadlighting should be ecologically designed while simultaneously considering energy efficiency and the regulations needed for safety reasons. The aim of this study was study designs of different dimensions regarding energy efficiency, ecological impact and the compliance with regulations for traffic safety. By using DIALux evo simulations with four different LED luminaires, different scenarios of road lighting designs (pole distance of 10m, 25m and 40m, and pole heights of 3m, 5m, and 8m) on a 7m wide road was evaluated. Ecological thresholds of 1 lux and 0.1 lux are possible to get below at distances from the road edge between 5–11m, and 8.5–20m, respectively. Results are discussed from the perspectives of increased demand on energy efficiency on road lighting.
