Spatial analysis of the impact of urban defenseless spaces on urban theft crime (Case study: Tehran Harandi neghborhood)

Defenseless spaces have different effects on urban spaces and the lives of citizens, which have the greatest impact on increasing crime and reducing citizens' sense of security. This is especially true in urban worn out and inefficient texture. The purpose of this study was to investigate the relationship between defenseless spaces and theft at Harandi neighborhood level. For the purpose of this research, this research is a part of applied research and is a part of descriptive - analytic research component. The data collection method was documentary-survey. To determine the unsafety of a different part of the neighborhood at the first, the neighborhood is divided into 20 blocks based on local trails and then from 22 sub-indicators in the form of 5 indicators of defenseless spaces. Using entropy and viquor method, weighing and ranking of different parts of the neighborhood have been addressed. A geographic weighting regression has been used to investigate the relationship between defenseless spaces and theft offenses. The results of the research have shown that the relationship between the defenseless spaces at the neighborhood level is not the same. In this research, the greatest relationship has been between defenseless areas and theft crimes in the eastern neighborhood, especially in the southeastern neighborhood of the neighborhood and in accordance with Shoosh park between Shoosh streets, Ray street and Anbar - e – Gandom street. In contrast, the least relation between defenseless space and theft was also in the western and northwestern neighborhoods. With regard to the relationship between defenseless spaces and crimes (robbery), with the reduction of defenseless spaces, some crimes can be prevented.
