The civil engineering department of the city of Kassel uses the Vissim system from PTV to simulate traffic flows in various planning variants. On the occasion of the planned redesign of the critical traffic junction “Brüder Grim Platz”, it was necessary to show the traffic simulation in three dimensions in the digital city model in order to communicate with citizens. A software interface developed by UVM Systems enables Vissim to be directly linked to CityGRID^® Scout. All road users simulated by Vissim – cars, trams, cyclists, pedestrians, etc. – now move through the 3D city model in real time. In this way, the spatial effects of a particular traffic planning variant on urban space can now be assessed much better within the framework of citizen participation.
