Responsible use

Goal and impact

This is a pilot project. The aim is to measure crowds. The algorithm is not meant to recognise people or do anything with personal data.

Considerations

It is a privacy-friendly way of measuring pressure.

Human intervention

Yes, the traffic controller acts on the data. Citizens will face the effect of the algorithm when roads may be closed and diversions formed during large crowds.

Risk management

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.

Legal basis

Municipal Act. Article 172 Public order enforcement (camera images) and Article 151C (processing camera images under police direction).

Elaboration on impact assessments

A Data Protection Impact Assessment (DPIA) was carried out.

An ethical impact assessment (AIIA) was done at a precursor to this experiment. This experiment used the Digital Mirror City Ethics Framework.

Operations

Data

Camera footage.

Technical design

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.

  • We record side placements and litter with images. From these images, we create information to measure cleanliness levels and monitor objects. The goal is better maintenance planning.

  • Automatic Number Plate Recognition cameras (ANPR) at four different locations record license plates of passing motor vehicles. The algorithm checks whether an exemption has been granted and determines whether photos are submitted for review in the enforcement system.

  • The algorithm uses sensor data to make a calculation for predictions of slipperiness risks. These predictions are used to determine where to grit (preventively), in consultation with meteorologists. In addition, the algorithm can issue various alarms, for example when there is a chance of wet road sections freezing.

  • This algorithm has a low impact. The algorithm is used to convert signals coming into the mmWave sensor into a number that represents the of the number of people in front of the sensor.
