The Pittsburgh Parking Authority’s License Plate Reader program, which was set up to pick out scofflaws from the countless rows of parked cars on Pittsburgh’s streets, has allowed its records to accumulate for up to 30 days.

Anyone with access to the database – which is available to the public through a simple Right-to-Know request – can access those backlogged records and use them to track the movement of Pittsburghers throughout the city.

Each dot represents the number of snapshots taken in a given block. Enter your license plate to see how many times you were photographed in August.
