Abstract

Urban management is an important content of social management, which is related to people's livelihood and social harmony. With the rapid advancement of urbanization and the continuous expansion of urban scale, urban management faces greater challenges, and it is very important to complete urban management efficiently and effectively.

Focusing on smart city management work in the central city of Zhengzhou, the study examines street patrol cases in the categories of urban environment and street order. The main findings are as follows:The analysis by the space-time cube model shows that street order case hotspots have seasonal characteristics on monthly data.
