Responsible use

Goal and impact

The bridge operator will be provided with advice that will better coordinate a bridge opening with road and water traffic; to improve flow in a thorough and fair manner.

Considerations

Automating the processing and weighting of data makes it possible to support the bridge operator in a potentially complex decision with information from more different sources.

Human intervention

The system provides a bridge operator with a 'ready-made' operating advice, but the bridge operator is free to follow the advice or not. To confirm this, the extent to which operating advice is deviated from is structurally monitored and analysed.

Risk management

All decisions are recorded and analysed to monitor the effective functioning of the system. Comments and complaints from residents and (waterway) road users are also analysed.

Legal basis

The Province of North Holland ensures the smooth and safe flow of traffic.

Operations

Data

The algorithm uses anonymised current 'track and trace' data from ships and road traffic, including public transport, ambulances and other emergency services with urgency. It also uses weather data, data from other bridges and locks, and data on waterway works.

Technical design

The algorithm calculates an optimal moment for opening a bridge using calculation rules and weights for the different modes. These weights are set in a priority model.

  • Web application Impact monitor Bridge opening

    Province of South Holland

    A web application that supports bridge operators in choosing the optimal time for a bridge opening. Traffic flow and emissions (carbon footprint) are taken into account. The application is equipped to predict traffic flow up to 21 minutes ahead in combination with up-to-date (real-time) traffic information.

  • Robot process automation in the WOZ objection (chain) process

    Municipality of Tilburg

    To support the performance of administrative operations in the WOZ (chain) process, algorithms are used. Robotic Process Automation (RPA) is the method we apply. In RPA, repetitive, rule-based operations are automated using algorithms.
