The mechanism of using the geographic information system in detecting unsafe spaces in the municipal areas of big cities (Investigation of unsafe places in the city of Dallas, Texas, USA)

For a long time, identifying the environmental and spatial factors of crime and trying to eliminate these factors or reduce their effects has been known as the most important way to increase safety and prevent the occurrence of anomalies. Because social anomalies, no matter how they happen to humans, have a place and place and time characteristics. Which distinguishes these behaviors from each other. Surveys show that some urban spaces have a higher crime rate due to their physical, social, and economic characteristics; a city is a collection of special mutual narratives that originate from the role and context of its internal institutions. Therefore, without providing a subjective definition, we accept the existence of the city based on objective characteristics, that is, the quality of the structure of the society and its economic and administrative role, not just the population quantity. Also, some thinkers have provided a comprehensible definition of urban space "Urban space is an organized, decorated, and orderly structure for human activities". Part of human actions and activities take place in place and space, and according to Anthony Giddens, "space is a physical set for social interactions". And on the contrary, some spaces prevent and prevent crimes from being committed inside them. On the other hand, research has proven that criminals often make rational choices when committing crimes and look for the simplest, least dangerous, and most suitable opportunities and conditions in place and time to commit crimes.
