Goal and impact

Information-driven enforcement:

Four algorithms are being developed within the Digital Moat for information-driven enforcement. So far, fairway inspectors have not imposed sanctions based on these algorithms. The algorithms are not yet in use because they must first be assessed for legal and municipal requirements and applicability. A detailed description will be added to the register when the algorithms are put into use.

Reporting passenger shipping speeding:
There is a speed limit on Amsterdam's inland waterways to prevent unsafe situations and nuisance. Exceeding the speed limit causes unsafe situations and nuisance, especially due to wave action. The algorithm uses AIS data from passenger vessels to measure speeding. The model works with a calculation rule that determines whether a vessel is travelling faster than the applicable speed limit (plus uncertainty margin) at least two consecutive times. The model is under development and not in use. The algorithm is applied to create a heatmap. In other words, providing an overview of the spatial distribution of speeding and highlighting specific vessels. The reporting is intended to make monitoring and enforcement more efficient and may lead to calling shipping companies to account for observed violations. No automated decision-making is used.

Considerations

The Digital Canal:

The Digital Canal measures traffic on Amsterdam's inland waterways. The project started in 2019 under the Sailing programme. The Sailing programme falls within the Space and Economy cluster. For the project, sensors have been placed along the inland waterways in the city centre and the main waterways outside the centre of Amsterdam. By deploying these sensors, the municipality is developing a dynamic traffic model and tools for information-driven enforcement. This is done with the help of algorithms. The calculated traffic data is processed and presented in a digital overview (dashboard). The dashboard is accessible to policy advisers, nautical managers and waterway inspectors.

Six algorithms are used within the Digital Moat: two for traffic monitoring (Pressure per channel and waterway traffic model) and four for information-driven enforcement (Detection of illegal passenger shipping, Reporting speeding passenger shipping, Detection of noise nuisance on the water and Reporting mooring use passenger shipping). Now, the algorithm Reporting Passenger Speed Exceedances is described.
