This dataset contains performance metrics tracked by the Chicago Department of Transportation (CDOT). Thirty-five different performance metrics are tracked in this dataset, which reports the performance target, actual performance, and number of requests completed for a given metric. These metrics are based on data calculated from the city's 311 system. Individual breakout of each performance metric are also available under the "More Views" button.

When moisture seeps into pavement, it expands when it freezes and contracts when it thaws. This flexing of the pavement, combined with the melted water and the stress of vehicular traffic, causes pavement to deteriorate and potholes to form. The Department of Transportation (CDOT) responds to potholes reported through 311’s Customer Service Requests (CSR) system by mapping open pothole requests each morning and routing crews in geographic clusters so as to fill as many potholes as possible per day. This metric tracks the average number of days CDOT takes to complete pothole repairs per week. Total number of requests fulfilled per week is also available by mousing over columns. The target response time for pothole repairs is within 7 days.
