Revolution in design for exceptional engineering

Take the creation of single and multilane 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 patent pending Vehicle Envelope Method® 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.

USP Enter a roundabout revolution

Enter a roundabout revolution

TORUS was developed over a course of 2 years by Transoft Solutions’ team of engineers working tightly with our software developers. Meticulous research went into the planning of TORUS involving both GPS field studies to support the algorithm development and continuous software testing to ensure quality and performance.

USP Patent pending technology

Patent pending technology

TORUS delivers a truly unique, time-saving, and productivity accelerating approach to designing roundabouts. Incorporating the AutoTURN engine, TORUS uses vehicle swept path movements and speed as the design criteria.

USP Determine the best layout

Determine the best layout

TORUS ‘drives’ the vehicles through the roundabout (applying the design guidelines for each major geometric element) to determine the layout as opposed to conventional manual methods where the design is first drawn and then checked using vehicle templates.


The next evolution in roundabout design

The new TORUS Roundabouts 5.0 release from Transoft Solutions 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. This new version represents the most sophisticated roundabout design software available in the industry. Designing roundabouts that meet traffic operations, site constraints and safety performance measures has never been easier.
