Goal and impact

The purpose of the algorithm is to recognise license plates of vehicles in violation for after-tax parking tax and Penalty Environmental Zone (Mulder Act) respectively. A citizen encounters the outcome of the algorithm in case of an offence.

Considerations

This is in addition to manual enforcement. The algorithm supports the process of determining if a car is parked incorrectly (Fiscal Parking Enforcement) and determining if a car/truck is driving in a certain area incorrectly (Environmental Zones Enforcement). A DPIA was carried out to determine the impact on privacy.

Human intervention

There is intervention by a BOA (yes/no naheffing/fine or. Yes/no admissible/founded objection). This process and information flow through the BOA (investigating officer) on duty. The BOA checks whether the license plate has been properly scanned before issuing a fine.

Risk management

Procurement of services from ISO-certified suppliers. Algorithms remain vested in the suppliers. A processor agreement and DPIA are in place to minimise risks to the municipality and citizens.

Legal basis

Municipal ordinances for tax parking enforcement and enforcement Environmental zones.

Impact assessment

Operations

Data

RDW, Licences/permits, GBA, National Parking Register

Technical design

A camera scans license plates. The algorithm combines data from the RDW/ permits, GBA and National Parking Register based on predefined rules (parameters) to determine whether there is wrong parking or unjustified driving in an Environmental Zone. Ownership of the algorithm rests with the suppliers. The municipality purchases services and has no direct involvement in or substantive knowledge of how the algorithms work.

  • Short description With the scan car, the municipality carries out parking checks. The scan car uses Automatic Number Plate Recognition (ANPR) cameras, identifies license plates and checks parking entitlements. The license plates without parking rights are transferred to the enforcement system for the purpose of collecting the parking tax due.

  • The municipality conducts parking checks using scan cars. The cameras on the scan car use an image recognition algorithm to recognise license plates and check whether the vehicle is allowed to park there.
