SafeNight is a walking app that helps pedestrians find safer routes at night. It scores each street segment on six factors: crime density, street lighting, CCTV coverage, road type, open businesses and foot traffic. It suggests alternative routes with turn-by-turn navigation, runs on Android and the web, and has a free tier.
What does SafeNight score?
Each street segment is rated on six factors. The weights change between late night (0 to 5 am), evening (6 pm to midnight) and daytime, so the same street can score differently at different times.
•
Crime: recent police-reported incidents nearby, weighted by severity.
•
Street lighting: lamp density, lamp quality and roads tagged as lit.
•
CCTV coverage: mapped CCTV cameras nearby.
•
Road type: main roads score safer than footpaths and alleys.
•
Open businesses: shops and cafés nearby, which reduces risk.
•
Foot traffic: an estimate of how many people are likely to be around.
Where does the data come from?
Crime data comes from the UK Police data portal, which covers England and Wales. Lighting, road, CCTV, shop and transit information comes from OpenStreetMap, read through the Overpass API. Crime data is only available where that portal publishes it, so scores are not available in every area. See the FAQ for more on coverage.
How are routes chosen?
SafeNight searches for walking routes with a cost that includes safety, and offers three to five alternatives, removing near-duplicates. Each route is split into short segments of roughly 50 to 80 metres, coloured green, yellow or red by risk. The route score is built from those segment risks.
Why can a safer route be longer?
The search does not only look for the shortest walk. Because safety is part of the cost, a safer route that avoids poorly lit or higher-risk streets can be longer than the most direct one.
What can't the score tell you?
A score is an estimate built from public data. It can be incomplete or out of date, and it does not guarantee that a route is safe. Compare the plans or read the FAQ.
