Baltimore City Parking & Camera Citations

Source: Baltimore City open data (ArcGIS) · Data as of July 19, 2026 · 9 pages

$334.4M in open citation balances across 2.98 million citations — 27% of every citation ever issued. Penalties, not fines, make up roughly 71% of the sampled open balance, and camera citations account for 66% of open volume but only 30% of open dollars — an awareness problem more than an ability-to-pay problem.

New York City Parking & Camera Violations

Source: NYC Open Data (Department of Finance) · Data as of July 19, 2026 · 7 pages

$1.72B outstanding across 14.1 million open violations. In the sampled open-balance rows, 90.8% had already gone to judgment, and 41% of the charges levied were penalty and interest rather than the underlying fine — costs that timely notification avoids. About 43% of open rows sit on out-of-state plates.

San Francisco Parking Citations

Source: DataSF (SFMTA) · Data as of July 19, 2026 · 6 pages

1.50 million citations and $166.4M in fines in one year across 531,743 distinct plates. Repeat plates dominate: vehicles cited two or more times received 78% of all citations and dollars, and the most-cited plate drew 314 citations in twelve months — a notification and behavior problem, not an enforcement gap.

Norfolk Parking Citations

Source: Norfolk Open Data · Published window Jan 2022 – Mar 2024 · 8 pages

44.8% of citations go unpaid — $2.88M outstanding in the city's most recent published window. Unpaid citations average $142 versus $126 for paid ones as late penalties compound, and the 2022 cohort was still 35% unpaid after more than two years of collection time.
