Simulate Mobility — Down to Every Interaction

PTV Vissim digitally reproduces the traffic patterns of all road users on a microscopic scale, using science-based motion models for pedestrians, vehicles (lane and non-lane based), micromobility and AVs. The software allows you to evaluate and optimize the performance of transport infrastructure, make data-based planning decisions, and proactively tackle challenges such as congestion, emissions, and the fair and safe distribution of road space. PTV Vissim is furthermore being used for the simulation of crowds and the automotive development. 

Safe & Sustainable Urban Mobility

PTV Vissim empowers users to simulate walking, cycling, public transport, road space redesign, and emission strategies in one behaviorally realistic environment. By making safety, reliability, congestion, and environmental impacts measurable, it turns complex trade-offs into evidence-based decisions. Build sustainable mobility with confidence — not assumptions. 

Discover how PTV Vissim makes safety, sustainability, and performance measurable in one integrated model.

Planning & Development of New Areas

PTV Vissim is the authority-grade traffic simulation platform that de-risks residential development projects before construction begins. It delivers true behavioral realism, integrated multimodal modeling, and approval-ready outputs that withstand planning scrutiny. By capturing street-level interactions and operational impacts, Vissim ensures new neighborhoods perform as intended — not just in theory, but in real-world operation.

Explore how behavioral microsimulation ensures new neighborhoods perform as planned — from day one.

Complex Movement & Crowd Planning

PTV Vissim along with PTV Viswalk enable validation of complex pedestrian and multimodal movement in high-density environments. They combine behavioural pedestrian reality with integrated vehicle interaction in one unified simulation platform. This ensures safe, efficient, and defensible planning decisions for infrastructure where crowd dynamics and operational risk are critical. 

See how multimodal simulation strengthens decision-making where crowd risk and movement complexity matter most.

Automotive Development

PTV Vissim's traffic simulations can be used to create reactive test environments for virtual vehicle development. The software 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. 

Discover how PTV Vissim advances the development of powertrains and ADAS/AV software.
