The Windy City’s Dark Side: A Statistical Exploration of Crime in the City of Chicago

Journal of Data Analysis and Information Processing 2024年第3期12卷 370-387页

This paper presents a detailed statistical exploration of crime trends in Chicago from 2001 to 2023, employing data from the Chicago Police Department’s publicly available crime database. The study aims to elucidate the patterns, distribution, and variations in crime across different types and locations, providing a comprehensive picture of the city’s crime landscape through advanced data analytics and visualization techniques. Using exploratory data analysis (EDA), we identified significant insights into crime trends, including the prevalence of theft and battery, the impact of seasonal changes on crime rates, and spatial concentrations of criminal activities. The research leveraged a Power BI dashboard to visually represent crime data, facilitating an intuitive understanding of complex patterns and enabling dynamic interaction with the dataset. Key findings highlight notable disparities in crime occurrences by type, location, and time, offering a granular view of crime hotspots and temporal trends. Additionally, the study examines clearance rates, revealing variations in the resolution of cases across different crime categories. This analysis not only sheds light on the current state of urban safety but also serves as a critical tool for policymakers and law enforcement agencies to develop targeted interventions. The paper concludes with recommendations for enhancing public safety strategies and suggests directions for future research, emphasizing the need for continuous data-driven approaches to effectively address and mitigate urban crime. This study contributes to the broader discourse on urban safety, crime prevention, and the role of data analytics in public policy and community well-being.

Vulnerability of Large City and Its Implication in urban Planning: A Perspective of Intra-urban Structure

引用

Chinese Geographical Science 2011年第2期21卷 204-210页

作者： XIU Chunliang CHENG Lin SONG Wei WU Wei School of urban and Environmental Sciences Northeast Normal University Changchun 130024 China Department of Geography and Geosciences University of Louisville Louisville K Y40292 USA

Vulnerability is a new field and analytical tool in the study of urban safety. Analysis and assessment of vulnerability provide a new basis for urban planning. This study constructed a quantitative index system for assessing vulnerability, based on the city′s sensitivity and emergency response capacity. City size, density, and spatial form influence a city′s sensitivity to crises and risks, to which vulnerability is positively related. Levels of socio-economic development, infrastructures, and emergency management contribute to a city′s emergency response capacity, with which vulnerability is inversely associated. Vulnerability of 19 large Chinese cities was assessed. Harbin and Shenzhen demonstrated the highest and lowest vulnerability among 19 cities, while Beijing, Shanghai and Guangzhou ranked the 5th, the 9th and the 12th. Spatially, northern cities tended to be more vulnerable than southern cities. And the differences in vulnerability among cities were explored based on cities′ physical geography conditions, level of socioeconomic development, infrastructures, regional status, history of disaster, history of urban planning and development, government policies, etc.

Journal of Civil Engineering and Architecture 2013年第5期7卷 609-615页

Large-scale national disasters have recently occurred worldwide, causing tremendous damage to life and property. Therefore, urban safety has become a critical issue, and disaster prevention and mitigation are also considered in urban development and infrastructure construction. When earthquake disasters occur, road networks play major roles in rescue activity for responding to urban damage. The urban-disaster prevention spatial system attempts to mitigate hazards by considering shelters, routes for evacuation and rescue and necessary logistics. A literature review shows numerous studies related to a disaster-prevention shelter survey before or after hazards, however, they are less concerned with the reliability of shelter evaluation. This study assesses shelter evaluation by considering road networks. The authors construct 10 selected indices individually related to road networks. Three integrated composite indices are established to explain planned-shelter risks using the Arc GIS diagram of a spatial concept of an urban-planning review process. The relationship between shelters and evacuation/rescue routes is important for disaster-prevention planning. This survey investigates the factors of road networks, fire engine rescue routes, fire station location and road/population density for vulnerability evaluations.
