Tritone is a micro-simulator road networks developed completely in Italian or English from the University of Calabria – UNICAL (TIS Group) as an innovative tool for the modeling of traffic flow.


What is micro-simulation?

The micro-simulation is used to represent in a timely, accurate and specific traffic and its instantaneous evolution, taking into account the geometrical aspects of retail infrastructure and the actual driver behavior, linked to the coupling characteristics of the vehicle and driver.


What can reproduce

Tritone is able to represent in a timely manner, precise and specific the traffic and its evolution instantaneous, taking into account the geometrical aspects of detail of the infrastructure and the real behavior of drivers, linked to the coupling of characteristics of the vehicle and the driver’s. In detail, Triton can simulate signalized intersections and not, roundabouts and bus traffic.

What’s Tritone?

Tritone was established with the aim of becoming a simulation tool not only efficient analytically, but especially from a usability perspective, reflecting fully the trends’s user friendly, which aim to simplify as much as possible the operations that the user must perform. In fact, in this regard, it is noted that all possible operations, are fully accessible through the convenient graphical interface. Then the user will not be forced, in its use, to make use of third-party software such as Excel or other, for the insertion of data in the network.


Output of Tritone

Tritone returns the results both in analytical form, based on control intervals defined by the user, both in graphic form 2D, developed for computers with low performance, so as to expand its range of compatible hardware, and in both three-dimensional field for 3D impact more pleasant and accommodating of the simulated network.

Ready for research

Tritone was built primarily from research and research therefore tends also a hand to researchers and scholars who wish to validate their simulation models by giving them the ability to place them inside of Tritone; by means of a standardized library.


Academic and Students version

Alert for new Microsoft Windows operation system

In the new Microsoft Windows operating systems must start Tritone or its installation package with administrator privileges by clicking on the software icon and selecting “Run as administrator“. This will guarantee a perfect operation of the software.


Software activation

Tritone is a free software that requires only a small activation to do during the first start of the product.

WARNING !!! Many times it may happen that your system can read our emails as spam due to server problem at our university, so please check the arrival of the license also among the junk mail or spam.


Errors corrected and software update

Over the years, several fixes have been made to the Tritone software, up to lead to a complete rewrite of the product. On the following page you can find plenty of information on what was done chronologically.
