Road and roundabout Designers


Software to create single and multi-lane roundabouts


Customise vehicle swept paths to model the geometry

Traffic Management software


Take the creation of single and multi-lane roundabouts to another level of productivity with full control and feedback during the roundabout design process. Designing optimal roundabouts that meet traffic operations and safety objectives has never been easier.

Powered by the trusted AutoTURN® engine, TORUS® uses the Vehicle Envelope Method® (U.S. Patent No. 8,650,004) of design to generate roundabout geometry with vehicle swept paths. This innovative approach allows for real-time, interactive designing and dynamically updates any changes made to the entire roundabout layout.

Engineers with all levels of roundabout design experience will find TORUS invaluable for projects throughout the feasibility, preliminary, and planning stages.

What People are Saying

Right off the bat, (TORUS) was very user-friendly and all the menus are very straightforward. I was able to do everything I had done previously and more on that complex intersection within minutes. It took me ten minutes to do what I had done with the other software in three weeks.
