20.500.12556/RUL-175342 Evaluating the impact of street lighting configurations on the accuracy of pedestrian obstacle detection findings from an onsite experiment Street lighting serves to enhance pedestrian safety, such as by improving visibility and helping to detect obstacles at night, while also minimizing energy consumption to support sustainability goals. This study investigates the impact of lighting parameters—specifically horizontal illuminance and uniformity—on pedestrians’ ability to detect small obstacles, highlighting a critical consideration in designing urban lighting that ensures both safety and efficiency. Fifty-six observers performed detection tasks under 14 lighting conditions, each involving 14 lowreflectance (gray) obstacles measuring 20 × 20 × 20 mm. Detection accuracy plateaued when maximum, average, and minimum illuminance (Emax, Eave and Emin) reached 6.7 lx, 1.94 lx and 0.98 lx, respectively—indicating no additional benefit to obstacle detection beyond these thresholds. This plateau effect challenges conventional lighting practices that emphasize higher illuminance to enhance perceived safety. Instead, the findings support sustainable lighting strategies by identifying sufficient illuminance levels to ensure pedestrian safety while minimizing energy consumption and light pollution. This evidence aligns with global efforts to develop safer, more sustainable urban environments, demonstrating that optimized lighting design can meet safety standards without resorting to over-illumination. street lighting pedestrian obstacle detection accuracy urban environment sustainability urban planning javna razsvetljava zaznavanje ovir za pešce natančnost urbano okolje trajnostnost urbano načrtovanje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-24 10:30:52 2025-10-24 10:30:58 2025-12-10 03:40:43 0000-00-00 00:00:00 2025 0 0 7 str. art. 107574 Vol. 28 Dec. 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 628.9 2590-1230 10.1016/j.rineng.2025.107574 254614531 1-s2.0-S2590123025036278-main.pdf 1-s2.0-S2590123025036278-main.pdf 1 45B1D18E31FBFEF41A4061BE23FB6915 8fe811b148609821f40ce4dc7b23f61bacbdd0d180c511de6810a8e1afd0ccfc a3c09e27-b0b3-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220795 https://www.sciencedirect.com/science/article/pii/S2590123025036278 1 7acd21df-b0b3-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220794 Fakulteta za elektrotehniko 0 0 0
