Does it feel like the cops aren’t really doing traffic enforcement anymore?

I pulled more than seven million moving violation citations from DC Open Data‘s API.… Continue reading Reddit post

Huge amounts of the dataset have no state drivers license or license plate information: plate_and_lic_combined % 6,028,469 81.76 DC 1,130,953 15.34 MD 122,663 1.66… Continue reading Some changes to previous analysis

Isolating those tickets in the dataset that begin with either ‘F’ or ‘D’ reveals a subset of 6,484,450, or about 88% of all tickets. Of those, 4,321,029 are tagged with a value under the ATE_TYPE column generated by the algorithm (about 67% of those tagged with ‘F’ or ‘D’). Looking for those ticket values NOT… Continue reading Analysis Process 7/11/2022

According to Open Data DC, 138 cameras are managed by the District Department of Transportation (DDOT). The cameras, which are scattered throughout the city, are used as a… Continue reading Woke up this morning and wrote myself some code

I fetched 7,392,736 moving violations issued by The DC Metropolitan Police Department and partner agencies in Washington, DC. First up: drivers from which state are the biggest contributors to this list of malefactors? Unfortunately, not every citation has driver license information. Only 1,329,401 (or about 18%) of the total citations fetched contained an entry under… Continue reading Exploratory analysis of #dcopendata project
