CITY OF CHICAGO | DATA ANALYSIS INDEPENDENT STUDY | FALL 2019 XINRAN ZHENG
DESCRIPTION This is an independent study based on and extended from the Nolli map research of the city of Chicago. The Nolli map research was a group research project under the ARCH576 Urban Morphology Seminar. In the Nolli map research, participants seek to document the existing state of an area of the city of Chicago, to create a unique map which gives insights into the complexities of the city. The research result used in this independent research is a portion of the Nolli map of the city of Chicago. The downtown site Nolli map was done by the 2018 Fall Chicago Studio (area bounded by W Wacker Dr., South Lakeshore Dr., W Harrison St., and the Chicago River). The West Loop site Nolli map was done by the 2019 Fall Chicago Studio (area bounded by W Kinzie St., N Morgan St., W Harrison St. and Chicago River) The purpose of this independent study is to further understand the city space, not only the publicity of city space but also how would the city space shape the city in terms of security and attractivity. Furthermore, the research also tries to show how different characteristics of city spaces shape the behavior of people. The methodology of this independent research is to visualize data collected from the internet, (mainly from the City of Chicago | Data Portal: https://data.cityofchicago.org/) and compare the result with the Nolli map to see the interconnection between the city space and data.
CRIME 2018 This diagram shows the record of the crimes by the city of Chicago in 2018. The Density of circles shows the density of crimes in a certain space. People usually consider the streets with an elevated railway to be the most dangerous streets in the city. In downtown Chicago, those streets are Lake St., Wabash Ave., Van Buren St., and Wells St. However, the data shows that there is no direct connection between the crime density and the existence of the elevated railways. Moreover, on Wabash Ave., Van Buren St. and Wells St., the crime density is relatively low, compared to other streets nearby. Based on the data, the most dangerous streets in the downtown area are State St. and Michigan Ave. The diagram also shows that the crime density is higher on the south-north streets than the east-west streets.
