The Swedish Transport Administration is investigating if a traffic management system can be useful to minimize conflicts between different modes of transportation.

Traffic analysis using AIS-data

A new bridge is being built in the centre of Gothenburg, Sweden. The Swedish Transport Administration is investigating if a traffic management system can be useful to minimize conflicts between different modes of transportation. SSPA has supported this investigation and our experts has performed an extensive traffic analysis based on AIS and ship data. When using our database of AIS-data we have the capacity to map, describe and visualize traffic patterns on shipping lanes.

The construction of the new bridge, Hisingsbron, connecting the two sides of the river Göta älv in the city centre of Gothenburg has started and the purpose is to replace the old bridge, Göta älvbron. The new bridge has a considerably lower navigable height (12 meter compared to 18 meters) which means that a larger part of the ships and boats passing will need bridge openings. There is a risk that the bridge openings can cause disturbances and delays for the cars, cyclists, pedestrians and trams crossing the bridge. A traffic management system is investigated to minimize conflicts between different modes of transportation. SSPA has supported the Swedish Transport Administration in the development of this system with an extensive traffic analysis of ships sailing on Göta älv based on AIS-data and ship data. The analysis describes types and number of ships passing through Göta älv and analyses patterns in the traffic and how the lower bridge will affect the number of bridge openings. This is vital information for a successful design and implementation of a traffic management system.

SSPA and AIS-analyses 

Using our database of AIS-data SSPA has the capacity to map, describe and visualize traffic patterns on shipping lanes. Combining the data with our knowledge in hydrodynamics and energy management on ships also makes it possible to assess total energy consumption and emissions over geographical areas. The knowledge is also a valuable input in our risk assessments and analyses.
