In this episode of The Urbanist’s Lens, hosts Drew and Andrea dive into a question that’s often taken for granted: Does better street lighting actually make cities safer? They explore the complex relationship between urban lighting, crime rates, and perceptions of safety, going beyond the simple idea that brighter streets automatically mean safer communities.

Drawing from key studies like Chalfin et al.'s randomized street lighting experiment in New York and Atkins’ research on crime and fear reduction in the UK, they examine the evidence supporting—and sometimes challenging—the link between illumination and public safety. The hosts discuss how lighting not only impacts crime prevention but also shapes how people feel about their neighborhoods, influencing walkability, social interaction, and even economic activity.

Drew and Andrea also explore design strategies that complement lighting in creating safer urban spaces. They break down principles like Crime Prevention Through Environmental Design (CPTED), natural surveillance, and how active streetscapes can foster both real and perceived safety. Plus, they tackle the less obvious downsides—like over-illumination, light pollution, and the unintended social consequences that certain lighting choices can bring.
