Application
Purpose
This is a pilot project. The aim is to measure crowds. The algorithm is not intended to recognise people or do anything with personal data.
Impact
Citizens will have to deal with the effect of the algorithm when roads may be closed and diversions formed during large crowds.
Proportionality
It is a privacy-friendly way of measuring pressure.
Decision making process
Pressure measurement
Legal
Authorized body
The Hague municipality is the processing controller. Processing is carried out by the supplier AI Tech.
Formal grounds
Municipal Act. Section 172 Maintenance of public order (camera images) and Section 151C (processing camera images under police direction).
Human Rights Impact Assessment (IAMA)
No IAMA but an AIIA.
IAMA Description
Field not filled in.
Data Protection Impact Assessment (DPIA)
Yes
DPIA Description
After the pilot, technical development and management should be separated.

Use-case
Long description
The camera records, a number of seconds. The server right next to the camera counts the number of people and deletes the data. The algorithm is trained to recognise people in different situations such as for example on a bicycle, in a wheelchair or crawling.
Usage of base registries
No
Data sources
Camera footage.
Supervision
Monitoring
There will be 2x evaluations within the pilot.
Human intervention
Yes, the traffic controller acts on the data.
Risks
There is a risk of someone physically hacking the system. An ethical impact assessment (AIIA) was done in a precursor to this experiment. This experiment used the Digital Mirror City Ethical Framework. DPIAs were also done (the DPIA pressure measurement) describing the risks and measures regarding privacy. There is no bias, as individuals are counted without preference. The choice of where to hang the cameras was made together with the enforcers in the previous pilot.
Evaluation metrics
Signals should be valuable. Evaluations will be conducted. After the experiment, added value will be weighed against importance.
