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 6.0, the process is streamlined with dynamic feedback, making each iteration nearly effortless.
Flexible For Your Distinct Design

  • 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.


Take the complicated calculations out of the equation

AutoTURN does the math for you. Eliminate the challenges of calculating curves and modeling vehicles with different steering capabilities. Using a vehicle of your choice, AutoTURN will compute the space requirements and show you the results, so you can focus on the important safety and operational components of your design.

Boost productivity and explore the best design options

Save time and make better decisions. Quickly create simulations and check multiple maneuvers for all vehicles accessing the site. Smart tools and automated processes help increase productivity and reduce human errors. Great for discovering the best design option or modeling more complex scenarios such as traffic calming and site circulation analysis.

Tackle complex urban design and complete streets projects

Embrace the future of urban design. With AutoTURN Pro, you can simulate the movement and turning requirements of a variety of bicycle types to validate your design is safe for cyclists, pedestrians and motorists alike..

Test your design with a vast array of vehicles

AutoTURN Pro includes over 1300 vehicles in its manufacturer-specific and standard design vehicle libraries, so you can run a robust swept path analysis. Quickly search by library name and apply filters to define results. You can also set custom vehicle groups that match your country or local area design.

Visualize the impact in 3D

Run 3D simulations to check for potential conflicts with terrain and infrastructure or for presentation purposes. With AutoTURN Pro you can also easily illustrate, vehicle paths maneuvering forward and backward..

Review your results with quality diagnostic tools

The automated tools ensure your design aligns with the guidelines and safety requirements of local transportation agencies. You can also readily check any manually produced simulations to ensure key parameters meet design criteria. Produce detailed reports so that reviews can be done by peers or others—meaning you can get a quicker stamp of approval on your design..

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..

Non-circular Roundabouts

Elliptical, teardrop, dog-bone, peanut and other non-circular shaped roundabouts can be designed to address special constraints and geometric challenges..

    After all, I would not wish to put a great deal money on a wrist watch and fake richard mille end up dropping the idea (or even someone taking that) If you're sporting a Breitling replica you'll likely feel far more comfortable (not forgetting when you have a lot of cash, no one may problem whether it is real or otherwise not). Just read this great Breitling reproduction Navitimer to see by yourself.
    Using its 46 mm size, the actual highly polished fake richard mille metallic situation would wear very well due to the tapered lugs.
