The Effect of Urban Tissues on Spatio-Temporal Patterns of Theft Crimes (Case Study: Mashhad City)

The Tissues of the city is considered one of the elements of the urban form effective on the occurrence of theft crimes. Therefore, the current research seeks to investigate the effect of urban context on spatial-temporal patterns of robbery crimes in Mashhad. The research method is descriptive-analytical and based on spatial analysis models. The statistical population includes theft crimes in Mashhad in the period of 1390-1400. In order to analyze the data, Geoda and ArcGIS software and spatial-statistical models such as Moran's spatial autocorrelation and spatial-temporal cube model were used. The results of the research indicate that 58.9 percent of theft crimes have occurred in fine fabrics. In fact, uses with an area of 50-75 square meters have the highest amount of theft crimes. Investigating the effect of urban context classification on theft crimes showed that 60.43% of the thefts occurred in peripheral contexts (marginal areas of Mashhad city, areas 4, 5, 7, 15, 16 and parts of area 13). Also, 19/2% of crimes are in checkered patterns (localities located in the west of Mashhad), 14/6% in star patterns (the central part of the city and around the holy shrine of Razavi) and 5/7% in middle patterns (area 1 and parts of the region 2) has taken place. Investigating the spatial-temporal cube patterns of theft crimes in Mashhad city showed that in the peripheral contexts the pattern of theft crimes is of the type of new and scattered hot spots, which indicates the intensity of theft crimes in these areas, but in the checkered contexts, the pattern of crimes is of the type of cold spots is an increase that shows that theft crimes in these areas are increasing in recent years.
