Improved street lighting has been suggested as a measure that would both (1) increase the risks of detection of crimes and (2) reduce fear.[1] These suggestions are based on the assumption that crime is normally a covert activity and that offenders will assess the risk of being seen when deciding whether to commit a crime.[2] Hence, some argue that improved lighting will encourage increase the chances of being seen and therefore act as a deterrent against crime.[3]
Atkins and his co-authors, however, conclude that there is no evidence to support the hypothesis that improved street lighting reduces reported crime.[4] On the bright side, Atkins et al. also assess the response of residents to improved street lighting. They find that the attitudes, opinions and behavior of residents in a re-lit area did change.[5] Specifically, there is clear evidence that perceived safety by women when walking alone after dark had been improved in the treated area.[6] Perceptions of safety in the home, or in the street during daylight hours, were not affected.[7]
In addition, there was no evidence to suggest any significant changes in un-reported crime; in travel, particularly trips out after dark; on harassments or incivilities.[8] However, the reaction of residents to the re-lighting scheme was overwhelmingly favorable; and it is without doubt a popular measure.[9]
