This visualization depicts a Google Earth 3D representation of the estimated traffic congestion based on the average speed measured in street segments located in Chicago, IL. The values used were measured between 7:00 AM CDT and 10:00 AM CDT on the weekdays between August 5th, 2019 through August 9th, 2019. Lighter colored streets represent less congestion and faster speeds, while darker colored streets represent more congestion and slower speeds.
To create this visualization, the average speed values were first processed from the data feed. This data was then inputted into Google My Maps, where icons and line segments with colors based on the average speed values were placed on the street locations using the given latitude and longitude. The KMZ file was downloaded from this and imported into Google Earth Studio, where the fly-by animation was created.
The data feed used was generated by the Chicago Traffic Tracker (CTT), which estimates traffic congestion on Chicago’s arterial streets in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses.
