Torus 2.0, Transoft Solutions’ new version of advanced software for roundabout design, has been updated to include such new features as conceptual road grading design in 3-D. By minimizing iteration cycles in the design process, while incorporating speed, vehicle and sight distance checks, roundabout projects are developed quickly and efficiently. Powered by AutoTURN and featuring the patent-pending “Vehicle Envelope Method” of design, Torus continues to revolutionize the design of modern roundabouts.
