Abstract
Nighttime activities have significantly increased in cities, underscoring the growing importance of nocturnal lighting in fostering emotional stability and comfort of people. This study utilized simulated virtual reality (SVR) technologies to investigate the relationship between lighting environment and fear of crime in narrow residential streets. We created virtual models replicating a typical low-rise residential area in Seoul, Korea, diversified into eight environments representing different times of day with corresponding lighting scenarios (natural light, streetlamps, and interior building lights). One hundred recruited young adult participants were asked to experience four randomly selected environments and rate their perceived level of fear of crime while wearing a head-mounted display. The ordinal logistic regression analysis demonstrated that fear of crime was influenced not only by natural light but also significantly by artificial lights on streets and inside buildings. Specifically, while a decrease in natural illuminance contributes to an increase in fear of crime in general (especially shortly after sunset), the role of natural illuminance was minimized immediately after streetlamp activation. After p.m. 8:30, when other light sources are relatively constant, fear of crime was significantly influenced by the proportion of interior building lights turned on. In residential areas where preventing light pollution is also crucial, a comprehensive strategy is necessary rather than solely focusing on improving illuminance levels to create safe and comfort lighting environment.
