roundabout design

TORUS Roundabouts is the original roundabout design software that provides transportation engineers and planners with a unique and practical way to lay out a roundabout, while ensuring design vehicles and safety performances are simultaneously checked. Going well beyond a simple drafting tool, TORUS is an advanced analytical solution that uses the vehicle envelope method to integrate design vehicles’ swept paths into the geometric design.
