PTV Vissim is a multimodal traffic simulation software. It can be used for the evaluation of small to medium sized networks, from a single junction to an area of up to 10km x 10km. Vissim is a great tool both for demonstrating and understanding the existing traffic patterns and driving behaviours as well as assessing future changes in demand and/or infrastructure.
There are two different types of assignment available for a microsimulation in Vissim. With Static Assignment (SA) traffic follows predefined vehicle routes with no choice on the path selection. Dynamic Assignment (DA) is a path selection decision model applied to models where more than one route between an Origin-Destination pair is available. The assignment method for each model is defined based on the requirements of each simulation application.
Public Transport and pedestrian movements can also be modelled with Vissim, as well as autonomous and connected vehicles.
Vissim also allows for Mesoscopic modelling. This is suitable for medium sized networks where less detail is required, and which speeds up the simulation time. Hybrid simulation, combining micro and mesoscopic simulation in the same model allows for different levels of detail within the network, depending on the area of focus as appropriate.
A 3D view of the network provides visualisation of the simulation. It is a great presentation tool for both technical and non-technical parties.
