TORUS Roundabouts

The most comprehensive solution for roundabout design and analysis

TORUS® delivers a complete set of tools for roundabout design at its core. Everything you need from automated initial geometry to analyzing the safety of the design, providing a solid foundation for the upcoming phases.

Designed for all skill levels, TORUS makes your job easier, smarter, and more efficient by simultaneously balancing guidelines, safety and operation. Generating the initial geometry from a desired design vehicle and providing immediate dimensional and analytical guidance allowing you to reach project goals and design objectives faster and safer. Don’t get frustrated by the typical iterative manual process. With TORUS’ latest version, the process is streamlined with dynamic feedback, making each iteration nearly effortless.


  • Addresses special constraints and layout challenges with various types of circular and non-circular roundabouts
  • Complex projects get less complicated with easy 3D modeling and visualizations
  • Efficiently create your design in 3D and visualize details and angles that you can’t see in 2D
  • Ensure your design allows enough time and distance for drivers to react to obstacles with sightline, speed check and analysis
  • Easily generate the High Speed Approach design methodology as preferred by many DOTs


TORUS reduces the amount of time spent developing roundabout design drawings and plans. The software provides a comprehensive solution that allows users to:

  • Focus on engineering designs by eliminating taxing manual calculations, repetitions, and iterations.
  • Manage critical guidelines through active conformity notifications.
  • Be more productive with drafting designs using parametric drafting and dynamic design modeling.
  • Make informed design decisions with real-time safety and performance analysis feedback like fastest path analysis and sight line checking.

TORUS Roundabouts features

Advanced 3D Grading and Terrain Modeling
Go further with your road design by generating a 3D grading and terrain model to view profiles, super elevation and more. Tie the 3D model back into your existing terrain with ease to see how your design fits with the existing infrastructure and submit your completed design for construction.
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.
