Analysis on the relationship between invasion crime and street crime, and expansion to algorithmic design of build environments

在本研究中，我们考察了京都富士区入侵犯罪现场与街头犯罪现场的空间特征之间的关系。研究了环境设计中预防犯罪的基本算法设计方法。本研究的主要成果如下。影响该地区各类犯罪发生的主要因素是海拔，即海拔越高，入侵犯罪率越低。此外，如果估计那里的行人数量较少，入侵犯罪率往往会较低。我们进行了优化，通过替换建筑用途来最小化抢袋的空间显现模式。以前是商业建筑的地块变成了个人住宅。

In this research, we examined the relationship of spatial characteristics between invasion crime spots and street crime ones in Fushimi ward of Kyoto City. We also researched the basic algorithmic design method for crime prevention thorough environment design. Main results of this research are as follows. The major factor which influences each criminal occurrence in this area is altitude, i.e. as altitude increases, the invasion crime rate tends to be lower. Moreover, the invasion crime rate tends to be lower if the number of estimated pedestrians there is low. We did the optimization that minimizesthe spatial emerging pattern on bag-snatching by replacing building usages. Lots which were previously occupied with commercial buildings change to be occupied with individualresidences.
