Abstract

Lighting can affect the probability of crime. In order to establish safe and secure residential areas’ lighting environment, the elements for crime prevention are researched. Originally propose 14 assessment indicators of lighting environment which can be recognized subjectively and may influence crime rate. They are horizontal illuminance illuminance uniformity surround ratio vertical illuminance three-dimensional color rendering glare lamp pole height light pole distance lamp aesthetic lamp conciseness color temperata lamp distribution light source. The data came from residents in China. Through screening and giving weights by Analytic Hierarchy Process, there are 7 key assessment indicators left. Then give weights to the ultimate 7 key assessment indicators by Entropy Weight to verify their rank. The results show that 7 key assessment indicators have the same rank in contrast of the two methods. According to the crime prevention influence of the lighting environment, the sort is: vertical illuminance, horizontal illuminance, three-dimensional, color temperature, glare, uniformity of illuminance, color rendering.
