Multimodal Traffic Simulation Software

Evaluation and proof of traffic performance

Check the traffic performance of transport infrastructure and measures even before they are implemented. This helps you to identify the best design and avoid costly mistakes. PTV Vissim can realistically represent any form of road, bicycle, or public transport infrastructure (including rail) as well as footpaths in 3D. Parking lots, airports, train stations, large buildings or temporary measures can also be simulated and evaluated.

Evaluation of traffic technologies

With PTV Vissim, you can investigate and realistically simulate the driving behavior of connected and autonomous vehicles and their effects on traffic flow. Intelligent traffic management measures, such as public transport prioritization, variable speed limits or ramp metering, can also be evaluated in the virtual test environment. PTV Vissim is further used in the planning and optimization of traffic signals.

Automotive: Development and validation environment

Traffic simulation can be used to create reactive test environments for virtual vehicle development. PTV Vissim has interfaces to many vehicle simulation programs (e.g. IPG CarMaker, Virtual Test Drive, dSpace ASM, Simcenter PreScan, etc.) so that you can add realistic and reactive surrounding traffic to your virtual test drives. The intelligent, behavior model-based actions and reactions of the surrounding traffic create a continuous interaction with the system under test.

Simulation of pedestrians

PTV Vissim and PTV Viswalk depict pedestrians and their individual interaction with each other. City and traffic planners, fire safety officers, station, airport, and event managers - all of them rely on microsimulation to ensure safety and comfort for pedestrians, simulating evacuation scenarios, and checking e.g. passage widths, installation areas, travel times, and waiting times.

Pedestrian simulation with PTV Viswalk

Environmental assessment of traffic

Check how traffic engineering measures such as adapted traffic light control, intelligent traffic systems or different vehicle fleet compositions affect the traffic related emissions of pollutants and greenhouse gases and thus determine efficient options for optimizing traffic impact on air quality and the climate.

Emissions are calculated in the cloud by our partner Bosch, using detailed overall vehicle and powertrain models that differentiate between all emission classes.

Digital City Twin

PTV Vissim maps the entire traffic infrastructure, the control logic through to the most advanced traffic light control procedures and Car2X communication, and models the interaction of all road users on the basis of intelligent behavior models. You can integrate the simulation as a "traffic layer" in your digital City Twin and enrich it with additional data, for example buildings, vegetation, bodies of water or planning data such as upcoming construction measures. Define individual "what if" scenarios and use the combination of powerful KPI-based evaluation of traffic flow with realistic 3D visualization for stakeholder dialogues, for example.
