This visualization depicts a Google Earth 3D cluster map representation of the vehicle speed violation counts in school and park zones in January of 2018 in Chicago, IL. The City of Chicago uses this data in its Children’s Safety Zone Program, which has the purpose of the ensuring the protection of children and residents in safety zones, which are designated as a 1/8th of a mile boundary around the schools and parks. This cluster map gives a visual representation of which areas to increase law enforcement monitoring or which areas residents may need to be more cautious while traveling through these zones.
To create this visualization, the largest counts of violations per day were retrieved for each location in the month of January. This data was then inputted into Google My Maps, where circle markers were created with sizes based on the violation counts. The KMZ file was downloaded from this and imported into Google Earth Studio, where the fly-by animation was created.
