Responsible use

Goal and impact

The purpose of the scanning vehicle is to read the number plates of parked cars in order to enforce parking regulations.

Considerations

The scanning vehicle is used to support manual parking enforcement. This makes it possible to determine more quickly whether a car has been parked illegally or has not paid. A data protection impact assessment (DPIA) has been carried out to assess the impact on the privacy of all citizens.

Human intervention

The scanning vehicle issues a warning if it detects that a car has been parked illegally or has not paid the parking charge. The BOA checks this and then issues a fine if necessary. Furthermore, a data protection impact assessment (DPIA) has been carried out on the use of the scanning vehicle.

Risk management

The supplier of the self-service scanning machine (on the ‘scanauto’) must meet strict requirements regarding information security and privacy. In addition, agreements have been made with the supplier regarding the processing of personal data. These agreements are set out in a data processing agreement. Furthermore, a data protection impact assessment (DPIA) has been carried out. This assessment is reviewed every three years in order to reassess the use of the mobile scanning vehicle.

Legal basis

Section 225 of the Local Government Act and the Road Traffic Act 1994

Elaboration on impact assessments

A data protection impact assessment (DPIA) was carried out prior to the use of the scanning vehicle. A number of risks were identified during this assessment. These risks have been mitigated through a series of measures.

Operations

Data

The car’s registration number (RDW), its location (GPS), the time of the scan, a photograph of the registration number and the vehicle, a photograph of the area around the parked car, and the parking permit register (SHPV – ServiceHuis ParkeerVergunningen).

  • Control with a scanning car

    Municipality of Zaanstad

    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.

  • License plate camera enforcement scan car parking

    Municipality of Deventer

    The municipality monitors the enforcement of paid parking of vehicles using a scanning car with a camera. The scan car drives on roads within the paid parking area; records license plates of vehicles in parking bays; and checks whether a parking right is present. After physical inspection by parking enforcement officers, it is determined whether a fine will be imposed.

  • Parking enforcement - scanauto

    Municipality of 's-Hertogenbosch

    The local authority uses ‘scanauto’ vehicles to carry out parking enforcement checks. The cameras on the ‘scanauto’ vehicles use an image recognition algorithm to 1) recognise number plates and 2) check the parking authorisation database to see whether the vehicle is permitted to park there.
