The definitive software for fast and efficient roundabout planning and designing  
     
  Witness a completely new and dynamic way to create single and multilane roundabouts. With TORUS, designing optimal roundabouts that meet traffic operations and safety objectives has never been easier.
 
  Truly Revolutionary  
  TORUS gives you the ultimate in control and visual feedback during the roundabout design process. Based on the proven AutoTURN engine, TORUS takes an innovative approach of generating roundabout geometry using vehicle swept paths. This patent pending technology incorporates real-time, interactive designing and instantly updates changes to the entire roundabout.
 
  TORUS Detailed Review  
  TORUS revolutionizes the way modern roundabouts are designed. With speed, vehicle, and sight distance checks incorporated within the software, transportation engineers and planners can minimize the iteration process during the feasibility, preliminary, intermediate, and detailed design stages.  

         
  TORUS in Detail      
   Rounabout Design Elements   Roundabout Reporting Tables  
 
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.
 
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.
 
         
  Refine Roundabout Edges   Fastest Path Analysis  
 
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.
 
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.
 
         
   Design Display Options   Innovation at its Best  
 
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.
 
Utilizing 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.
 
         
   Sight Line Evaluation   Check Vehicle Movements  
 
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 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.
 
         
   Roundabout Management    Presentation Abilities  
 
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.
 
Animate vehicle manoeuvring simulations within the roundabout CAD drawing. Animations can be saved and exported to be used with Transoft Solutions InVision presentation software.
