Artificial light at night has many ecological consequences, including attracting or repelling certain animals. Dark corridors have been implemented in several regions to preserve or restore an ecological network conducive to nocturnal wildlife, maintain the quality of the night sky, and protect human health. These dark corridors are land-use plans that aim to reduce or delete specific light points and create paths of darkness, allowing for the movement of nocturnal species. As such, these corridors help preserve biodiversity and reduce energy consumption. However, they can also induce a sense of insecurity and modify the modal choice of night-time travel. In order to analyse the impact of public lighting on Walloons, we conducted a survey. This questionnaire has been completed by 685 citizens (allowing us to reach a 3.74% error margin, with a 95% confidence level). Our study enabled us to determine the evolution of the feeling of safety in different contexts and lighting conditions, the changes in modal split, and the acceptance of lighting reduction policies, respondents being or not aware of light pollution. Our results should help decision-makers determine appropriate policies in land-use management and, more specifically, public lighting. ; 9. Industry, innovation and infrastructure ; 11.
