Pedestrians feel safer while walking, if the streets are illuminated with white light.
Researchers from the University of Granada surveyed 275 pedestrians in “nocturnal urban environment”, i.e. participants of the study were given a test after walking in illuminated streets in a city.
Researchers were trying to know the thoughts of pedestrians about different kinds of public lights on streets, i.e. color of light and level of illumination. Those thoughts were related to perceptions of safety from different criminal activities. Moreover, thoughts were also related to general well-being as, for example, headaches, glare, and avoidance of stress.
After the survey, researchers found that people felt safer and better in well-illuminated streets having uniform and higher level of lighting. Moreover, they found that pedestrians felt safer in white light while walking in streets as compared to yellow lights.
This study showed that modern LED lighting is important to help people feel safer, and this point has also to be considered by urban planners, lighting engineers, and city administrators.
