| Abstract |
This research has addressed the natural surveillance visual exposure as one of the factors to affect the possibility of crime within a certain area of the urban space, and proposed an visual exposure as a means to quantitatively identify the natural serveillance. The visual exposure refers to the sum of the frequency of visits of each node which certain point in the visual approach from each node. If the visual exposure is high, the number of nodes that canbe visited within a limited distance would visual approach and the sum of the frequency of visits is high which means it would be harder for criminals to exposure, thus become less the probability of crime occurrence. The visual exposure allowed the probability of crime within a certain area of the urban space to be quantified. Furthermore, this research showed that specific changes to the urban spatial structure can adjust the visual exposure, thereby controling the probability of crime occurrence. |
