The effect of reduced street lighting on road casualties and crime in England and Wales


[2015] This study found little evidence of harmful effects of street lighting adaptation strategies - switch off, part-night lighting, dimming, or changes to white light/LEDs - on road Safety (collisions) or crime in England and Wales. There was no evidence that any street lighting adaptation strategy was associated with a change in collisions at night. There was significant statistical heterogeneity in the effects on crime estimated at police force level. Overall, there was no evidence for an association between the aggregate count of crime and switch off or part-night lighting. There was weak evidence for a reduction in the aggregate count of crime and dimming and white light.
