Responsible use

Goal and impact

Goal is to digitally enforce the local closure (traffic measure). Sub-goal Ringdijk: making embankment more car-free. The software is programmed to recognise and photograph the license plates of motor vehicles that pass the prohibition on entering the road. The software then ensures that the photo of the passage i.c.w. date, time, location and vehicle data is submitted to our enforcement system for evaluation. Impact: a license plate is recognised and registered. Based on control/algorithm, a boa (special investigating officer) is shown a selection of license plates of motor vehicles that are (possibly) in violation. The consequences range from nil to significant (being fined or not).

Considerations

The choice of a "soft cut" (closure by camera) will be laid down in the traffic decision. This will weigh the impact on stakeholders against the general interest.

Human intervention

An enforcer (always a boa) sees licence plates selected by the software on his screen and at that point can manually assess whether there is an offence. The enforcer can then draw up an official report and send it to the CJIB.

Risk management

Because personal data is processed, extra attention is paid to security. All data is processed in a secure environment.Security measures are contractually laid down in section 4.10 of the Service Level Agreement with supplier Sigmax.Only boas of the municipality and employees with a designation to view police data are given access to the data of observed offences. Data from other vehicles are also shielded from them. Deviations are reported directly to the supplier.

Legal basis

Section 18(1) WvW 1994 Regulation on domain lists of special investigating officers, Domain 1. Item 10: Article 62 RVV 1990 in conjunction with Appendix 1 Chapter C

Technical design

Image recognition. ANPR cameras at four different locations record motor vehicle license plates. The algorithm checks whether an exemption has been granted and determines whether photos are submitted for evaluation in the enforcement system. The vehicle data are enriched in the enforcement system through a link with the RDW.
