TORUS is advanced CAD-based software for the design of modern roundabouts. Powered by the trusted AutoTURN engine, TORUS takes the innovative, patent pending approach of generating roundabout geometries using vehicle swept path movements. This method minimizes iteration cycles in the design process while also incorporating speed, design vehicle and sight distance checks. And with dynamic editing features and immediate feedback on fastest path and sight lines, engineers and transportation specialists can use TORUS to produce optimal roundabout designs much more efficiently and reliably.

Generate single lane and multilane roundabouts based on design vehicle movements and clearance offsets. Specify inscribed circle and central island diameters, truck apron, and approach leg points. Modify the geometry of circulatory widths, splitter island envelopes, crosswalks and pedestrian refuges. Drag and rotate roadway legs around the central island. And any change to a design element or geometric parameter automatically updates all other design values in the entire roundabout layout.

Use TORUS to evaluate the fastest path a design vehicle can maneuver through the roundabout for capacity and safety analysis. User-defined parameters for superelevation, acceleration, and critical offsets can also be applied for calculations. Additionally, fastest path results and speed differentials can be reviewed during roundabout placement and can even be generated for roundabouts created outside of TORUS.

FEATURES & BENEFITS

Generate roundabouts based on vehicle movements and clearance offsets. Productivity is enhanced by using vehicle maneuvering and speeds as design criteria, rather than just as a checking method.
Drag and place the central island and inscribed circle which dynamically updates the entire design. Add and set leg parameters (entry/exit, offsets, widths, bypass lanes, and curb rounding).
Save, recall, and display multiple roundabout iterations for design review and comparison. Each roundabout design can have its own design symbol and independent set of iterations.

Fastest paths for a roundabout can be calculated and drawn based on offsets from reference geometries. Fastest path values are automatically updated.
Draw lines and arcs based on the locations of the roundabout edges that can be fine-tuned to more closely represent final edges.
Generate different types of sight lines including: approaches to crosswalk, yield line, and circulatory lanes.
Create and insert Fastest Path data tables (vehicle speed and travel path radii information) and Curve tables (dimensions for refined edge geometry).
Change the display properties for different geometric elements including inscribed circle, central island, truck apron, bypass and splitter islands, crosswalks, and lane radii.
