Take the creation of single and multi-lane roundabouts to another level of productivity with full control and feedback during the roundabout design process. Designing optimal roundabouts that meet traffic operations and safety objectives has never been easier.
Powered by the trusted AutoTURN® engine, TORUS® uses the Vehicle Envelope Method® (U.S. Patent No. 8,650,004) of design to generate roundabout geometry with vehicle swept paths. This innovative approach allows for real-time, interactive designing and dynamically updates any changes made to the entire roundabout layout.
Engineers with all levels of roundabout design experience will find TORUS invaluable for projects throughout the feasibility, preliminary, and planning stages.
Roundabout Design Elements
TORUS lets you drag and place the central island and inscribed circle while dynamically updating the design to fit their location. You can add and set leg parameters (entry/exit, offsets, widths, bypass lanes, and curb rounding). In addition, selected legs can be rotated around the central island.
Refine Roundabout Edges
Draw lines and arcs based on the locations of the roundabout edges that can be fine-tuned to more closely represent final edges. Using this functionality, you can produce labeled roundabout geometric elements and Curve Tables.
Design Display Options
Set and edit colours, line types and hatch patterns for text labels, design symbols, roundabout geometry, fastest path and, movement simulations. Change the display properties for different geometric elements including inscribed circle, central island, truck apron, bypass and splitter islands, crosswalks, and lane radii.
Sight Line Evaluation
Sight line analysis is an important factor for determining safety constraints in a roundabout. With TORUS, you can generate various types of sight lines (approaches to crosswalk, yield line, and circulatory lanes). Once placed, you can control their display and edit the properties used to define them.
TORUS allows you to 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.
Roundabout Reporting Tables
Create and insert Fastest Path data tables (vehicle speed and travel path radii information); Curve table (dimensions for refined edge geometry); Summary Report with all design information. Reports can be inserted in the CAD drawing or exported to text format files.
Fastest Path Analysis
Vehicle speed control is one of the most important features of roundabout design. With TORUS, the fastest paths for a roundabout can be calculated and drawn based on offsets from reference geometries. Fastest path values are dynamically updated.
Innovation at its Best
Utilising the proven AutoTURN swept path engine, TORUS generates roundabouts based on vehicle movements and clearance offsets. Productivity and efficiency is stepped up by incorporating vehicle manoeuvring and speeds as design criteria, rather than just as a checking method.
Check Vehicle Movements
TORUS lets you add, view, edit, and delete AutoTURN vehicle movements from a roundabout in order to demonstrate the movements governed by the vehicles specified in the current design guideline.
Animate vehicle manoeuvring simulations within the roundabout CAD drawing. Animations can be saved and exported to be used with Transoft Solutions InVision presentation software.
