NYC Open Data has some really interesting data sets available for download. Previously, I made a heat map using restaurant health grade data from this source. Here, I’ve graphed a database of 872,370 parking tickets issued during March, 2010.

I don’t usually use pie graphs because they are difficult to compare, but in this case, there is no need for comparing chart to chart. The first graph shows, of the cars ticketed, how many tickets each car got. Not surprisingly, most received only one, but about 10,000 had more than six tickets, and about 2,400 (possibly abandoned, but somehow not towed) had more than 20 tickets. Regarding the reason for the citation, the plurality was issued for violating no parking or no standing signs. The mode fine amount was $115 (36.7% of tickets), followed by $65 (24.4%), $45 (14.7%), and $35 (13.2%). Finally, as expected, most cars ticketed had local NY plates; the only other state above 3% was NJ at 9.7%.
