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.

Responsible use

Goal and impact

The aim is to use the parking scan car to detect illegal parkers faster and deploy enforcers more effectively with it.

The impact is that more cars can be checked in the same time. Which increases the chance of being caught. The cameras, and thus the algorithm, are deployed for the purpose of enforcing vehicle parking policies. The impact of the algorithm on citizens is low. Based on the license plates, the algorithm checks whether a parking right is present. For this purpose, the National Parking Register (NPR) is queried. If a parking right is detected, the license plate is deleted within minutes. In the absence of a parking right, the license plate is forwarded to the so-called Brickyard back office that the municipality of Deventer uses for parking enforcement. In this step, the license plate is enriched with public vehicle information from the RDW so that the enforcer can see which vehicle belongs to the license plate (Make, type and colour). Alleged offenders are manually checked by a parking enforcer to determine whether there is an offence, with the parking enforcer also physically checking the alleged offending car itself.

Considerations

Enforcing with a scanning car is faster, allowing the available enforcement capacity to be used more effectively. The same people can check a larger area. This is relevant because various policy developments have increased the area where people have to pay to park. Effective parking enforcement helps to reduce parking nuisance and thus contributes to improving liveability in a neighbourhood.

Human intervention

An enforcer checks on the spot if there is no overpayment and assesses the situation. If there is no special situation (for example, if the vehicle is registered with a disabled parking card), an after-tax parking fee (fine) follows.

Risk management

There is no live video footage; it is just digital images (photos) with license plate information. People and other vehicles that appear in the photos are blurred by the algorithm in 'real time' (while the photo is being taken). As a result, people or other vehicles are not recognisable. Vehicles where there may be no parking right are temporarily listed (for up to 72 hours). Information about other vehicles is deleted within minutes.

License plates for which a parking right is detected by the scan car are deleted immediately. License plates without this match are automatically deleted from the Brickyard platform after 72 hours (in accordance with the CVOM (Central Processing Office) directive). The license plates and images for which the absence of a parking right has been detected after human inspection; and on which an additional charge is imposed; remain stored in the Brickyard platform for 13 weeks for the purpose of going through the additional charge procedure and longer in the event of any objection.

Legal basis

Municipal Act (sections 225, 234 and 235) & the Municipal Parking Taxes Decree.

Elaboration on impact assessments

The municipality conducts a DPIA to test the impact of the solution.

Technical design

The scan car travels on public roads within the paid parking area and records license plates of the vehicles in parking bays. If there is no parking space based on the GEO card, the license plate is not registered. The same applies to the time of registration, such as outside paid parking times. Based on the license plates, it is checked whether a parking right is present. For this purpose, the National Parking Register (NPR) is queried. If a parking right is detected, the license plate is immediately deleted. In the absence of a parking right, the license plate is forwarded to the so-called Brickyard back office that the municipality of Deventer uses for parking enforcement. In this step, the license plate is enriched with public vehicle information from the RDW so that the enforcer can see which vehicle belongs to the license plate (Make, type and colour). The application automatically does a 2nd query of the NPR (5 minutes after initial registration) to determine whether a parking right has been purchased in the meantime.

A parking enforcement officer physically checks the vehicle and confirms whether or not there should be an after-charge. The after-charge is put on hold. In the evening, a re-questioning of the NPR is done ('moment registration scan car + 5 minutes'). If it turns out that there really was no parking right, the aftercharge can be sent. After 72 hours, all data from the scan car is automatically deleted, except for cases where an additional charge has been imposed.
