TORUS Roundabouts

A COMPREHENSIVE APPROACH TO YOUR ROUNDABOUT DESIGN

TORUS® gives you the right tools to design roundabouts smarter and more efficiently. It generates initial geometry honoring reference criteria, and provides real-time feedback regarding recommended dimensional and analytical ranges. Make edits to your design parameters and get instant feedback during the process.

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 during the conceptual, feasibility, preliminary, and planning stages.

TORUS Overview Video
The new TORUS Roundabouts release takes the evolution of this software to another level with new features for designing turbo roundabouts and checking vehicle paths and fastest paths on circular or non-circular roundabouts.

TORUS Roundabouts Features

3D ROUNDABOUT SURFACE GRADING
Generate roundabout grading with contour lines, crown alignments, and cross slopes to review drainage in 3D. Ensure approach roads enter and exit the roundabout at optimal grades and that the roundabout plateau does not exceed cross slopes affecting vehicle stability. Export grading into LandXML format for vertical CAD platforms. Free-form grade the central island regions to design tilted plane or even folded plane. Users can grade the central regions either from the exterior (Inscribed Circle Diameter) to the interior (Central Island) or from the interior to the exterior.
TURBO ROUNDABOUT DESIGNING
Design Turbo Roundabouts which consists of spiral circulatory lanes according to the design approach from the Netherlands. These type of roundabouts can be designed to reduce conflicting vehicle paths and limit driver decisions to increase traffic safety as well as speed and capacity performances.
