| Lighting influences safety and feelings of safety |
by Mateja Mihinjac
It’s that time of year again. Darkness lingers until nearly 7:30 a.m. and settles again just after 4 p.m. Coupled with weeks of fog that barely lifts, the city can feel like it’s sealed under a grey, misty dome. Echoes of occasional firecrackers in the distance, as we approach the festive season, further amplify feelings of unease.
We’ve written before about how lighting, and sometimes the absence of it, shapes how people experience safety, such as situations where turning lights off can actually reduce risk. This season brings those questions back into sharp focus.
On one of those foggy late mornings, I ran into an elderly man I often see during my dog walks. He told me he now makes sure to take his daily walk while it’s still light. Night walks, especially when combined with fog and poor lighting, make him uncomfortable.
It was a simple comment, but I understood immediately what he meant, shaped by years of working with how people experience safety in public space. And yet, surprisingly, discussions about urban lighting in my city are rare.

ANXIETY ABOUT THE UNKNOWN
From CPTED and SafeGrowth research, we know that nighttime environments differ fundamentally from daytime ones, both physically and socially. This is precisely why nighttime site visits and safety audits are essential. What feels manageable by day can feel uncertain or threatening after dark, especially when lighting is inadequate, and activity levels drop.
Research consistently shows that feeling safe and comfortable matters. Negative perceptions of safety influence how people use public space and are linked to poorer mental health outcomes, particularly among those experiencing high levels of fear.
Importantly, fear is often highly localised. My own field research on perceptions of safety in downtown Saskatoon showed that immediate, micro-spatial context matters more than broad neighbourhood reputation. Traditional social science surveys ask questions such as “Do you feel safe walking alone at night in your neighbourhood?”
That fails to capture where fear concentrates. The Saskatoon study zoomed in with more detail and focus. Results were featured in the 2019 Saskatoon Planning publication.

Studies that focus on very small areas, sometimes just a block around someone’s home, show that fear is strongly shaped by what people see and experience nearby. Five cues in particular signal trouble:
- signs of disorder,
- poor upkeep,
- obstructed sightlines,
- entrapment spots, and
- poor nighttime visibility.
Even when actual crime rates are low, these environmental cues can amplify anxiety.
The social life of a place matters as much as its physical form. Areas with little activity and visible neglect often feel unsafe, while everyday presence – people walking, talking, passing through – can offset even imperfect design.
A sense of community doesn’t emerge on its own. It depends on spaces that invite people to be there. And this is where lighting becomes critical.

A SOCIAL ANGLE WITH LUCI
The social environment matters just as much as the physical one. Sparse activity and visible social incivilities heighten fear, while the presence of others can offset poor design. In some cases, social factors outweigh defensive physical measures entirely.
A sense of community, collective efficacy, and everyday social presence can reduce fear, but only if the environment supports people being there in the first place. And this is where lighting becomes critical.
I recently came across LUCI – Lighting Urban Community International – an international network of cities focused on urban lighting as a tool for sustainable development, cultural and economic life, social cohesion, and quality of life.
LUCI challenges the idea that lighting is merely a technical issue. Instead, it frames lighting as a public health, social, and equity concern. Their research highlights how lighting influences sleep, mobility, safety, social interaction, and wellbeing, especially for vulnerable populations such as older adults.
Poorly designed lighting can isolate people, discouraging them from going out at night, thereby shrinking their world. Thoughtful lighting, by contrast, supports confidence and connection.

LUCI’s work highlights how urban lighting sits at the crossroads of many everyday goals that shape quality of life. It influences who feels included, how comfortably people move through a place, and whether streets and pathways feel legible and welcoming after dark. Lighting affects safety and natural surveillance, but also subtler things like social connection and the confidence to linger rather than hurry through.
It also carries environmental and economic weight. Decisions about lighting shape energy use, light pollution, and the character of nighttime activity in local economies. Just as importantly, lighting contributes to public health and overall wellbeing by setting the tone and ambience of public spaces.
Seen this way, lighting is not simply about preventing crime. It is about enabling life after dark and functioning as a form of social infrastructure, especially in places and seasons where daylight is scarce.

RECLAIMING THE NIGHTS
Making lighting part of urban planning means more than installing brighter fixtures and replacing sodium with LED lamps. It requires engaging communities and integrating lighting into broader governance and design decisions.
Socio-demographic analysis, co-design, and community-driven approaches are essential if lighting is to support wellbeing rather than undermine it. Such co-governance is necessary in SafeGrowth and in all the questions that affect the quality of life of residents.
That elderly man adjusting his walking routine wasn’t responding to crime statistics. He was responding to uncertainty that the darkness and the fog instilled in him. He was responding to a nighttime environment that no longer felt legible or welcoming. It had changed his world.
When cities get lighting right, they don’t just reduce fear. They give people their evenings back.
