‘Blauwe Golf Verbindend’ (The Blue Wave connects)

sluis-vlakbij-maastricht (1)

The ‘Blauwe Golf Verbindend’ (BGV) web portal collects and distributes real-time information on current and planned bridge openings. In addition, BGV provides information on the availability of berths in the ports of Amsterdam and Rotterdam. Using the data from the web portal, road and waterways navigation systems can factor bridge openings into their calculations, and skippers can easily find berths in the harbor.

Optimizing use on the water

BGV is one fruit of the Dutch Ministry for Infrastructure and the Environment’s Beter Benutten  (‘Optimizing Use’) program. The web portal offers skippers valuable support in their work, by giving them an immediate overview of current and planned bridge openings. By adjusting their speed they can then avoid having to lie idle for no reason – thus saving time, fuel, and money. As soon as a vessel approaches the port, apps using BGV data will show which berths are still free. The skipper no longer has to look for a berth and later relocations are no longer necessary.

Traffic control centers, ports, and shippers can combine the BGV information with real-time information about the location, direction, and speed of vessels to achieve optimal fine tuning. This also contributes to a more efficient logistical process.

Data from many sources

The BGV web portal is a ‘data bus’ that combines data from many sources, thus creating a single coherent flow of data. It is connected to existing systems such as FIS (Fairway Information Service), NDW (National Data Warehouse for Traffic Information), and systems of the provinces of Noord- and Zuid-Holland, and regional organizational units of Rijkswaterstaat. BGV receives sensor information on the statuses of bridges from the province of Zuid-Holland. The control systems of the ports of Amsterdam and Rotterdam use BLIS (Inland Navigation Berth Information System) to provide information on the availability of moorings. All of the data is enriched, bundled, and made accessible in BGV, and is then made freely available to any interested user through the NDW.

New data sources are constantly being added to BGV. Over the coming six months, 130 bridges will be added to the web portal. Rijkswaterstaat will also begin providing information about other berths in addition to Amsterdam and Rotterdam.

Better flow on the road

The BGV data on bridge openings will also be made available through our traffic management platform MobiMaestro, so that BGV can contribute to improving road traffic flow too. In the future, bridge openings can be aligned with each other to minimize road traffic disruption. Route information panels can communicate bridge openings to motorists, so that they can adjust their route if necessary. Messages for inland navigation, for instance on upcoming bridge openings, can be communicated to vessels using digital information panels along the banks of waterways.

This project is being carried out by Technolution and was commissioned by the Ministry for Infrastructure and the Environment under the ‘Beter Benutten’ program, in cooperation with the provinces of Zuid-Holland and Noord-Holland, Rijkswaterstaat, Port of Rotterdam, and Port of Amsterdam.
