PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Planung Transport Verkehr AG in Karlsruhe, Germany. It was first developed in 1992. The name is derived from "Verkehr In Städten - SIMulationsmodell" (German for "Traffic in cities - simulation model").
MATSim (the Multi-Agent Transport Simulation Toolkit) is an open source software development project developing agent-based software modules intended for use with transportation planning models. History
Simulation of Urban MObility (Eclipse SUMO or simply SUMO) is an open source, portable, microscopic and continuous multi-modal traffic simulation package designed to handle large networks. SUMO is developed by the German Aerospace Center and community users.
Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems. [1]
A read-only version of the software, VisSim Viewer, is available free of charge and provides a way for people who do not own a license to use VisSim to run VisSim models. [3] This program is intended to allow models to be more widely shared while preserving the model in its published form. [ 3 ]
The software has been generalized and abstracted from the UrbanSim model system, and is now referred to as the Open Platform for Urban Simulation (OPUS), in order to facilitate a plug-in architecture for models such as activity-based travel, dynamic traffic assignment, emissions, and land cover change.

Elmer - an open-source multiphysical simulation software for Windows/Mac/Linux. FlightGear - a free, open-source atmospheric and orbital flight simulator with a flight dynamics engine (JSBSim) that is used in a 2015 NASA benchmark [ 1 ] to judge new simulation code to space industry standards.
It is the only free transport model available today. [citation needed] Models in the system use discrete logistic regressions. This includes activity-location, land-choice, and most notably, multi-modal path choice and assignment. TRANUS is claimed to be superior to conventional transport models based on equilibrium assignment and user ...
