INDUSTRY LEADING SOFTWAREPowerful and InnovativeRoundabout Design Software
>> Get instant visual feedback for fastest path assessment. Review roundaboutgeometries based on the fastest path of a vehicle moving through the design.
TORUS is advanced CAD-based software for the design of modern roundabouts. Powered by the trustedAutoTURN engine, TORUS takes the innovative, patent pending approach of generatingroundabout geometries using vehicle swept path movements. This method minimisesiteration cycles in the design process while also incorporating speed, design vehicle and sight distancechecks. 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.
DYNAMIC ROUNDABOUT DESIGN
Accelerate the design of roundabouts with a full complement ofintuitive features. Generate single lane and multilane roundaboutsbased on design vehicle movements and clearance offsets. Specifyinscribed circle and central island diameters, lorry apron, andapproach leg points. Modify the geometry of circulatory widths,splitter island envelopes, crosswalks and pedestrian refuges. Drag androtate roadway legs around the central island. And any change to adesign element or geometric parameter automatically updates all otherdesign values in the entire roundabout layout!
INNOVATIVE ROAD GRADING
Instantly generate roundabout grading with contours lines, crownalignments, and cross slopes to review drainage patterns in 3D.Ensure approach roads enter and exit the roundabout at optimal gradesand that the roundabout plateau does not exceed stipulated crossslopes affecting vehicle stability. Grading models can be exported intoLandXML format to be used in different vertical CAD platforms.

FASTEST PATH ANALYSIS
Use TORUS to evaluate the fastest path a design vehicle can manoeu-vre through the roundabout for capacity and safety analysis. User-de-fined parameters for super elevation, acceleration, and critical offsetscan also be applied for calculations. Additionally, fastest path resultsand speed differentials can be reviewed during roundabout placementand can even be generated for roundabouts created outside of TORUS!

MANAGE AND REPORT YOUR ROUNDABOUTS
The TORUS Design Manager provides a one-of-a-kind ability to manage multipleiterations of roundabout placements and varying design criteria within a singleCAD drawing. All key parameters can be saved, recalled, and reported on forcomparison between different roundabout iterations to aid in the selection ofthe optimal preliminary layouts to move on to the final design stage.
>> Produce all required roundabout geometries including the inscribed circle diameter,the diameter of the central island, circulatory roadway, and much more.
>> Generate various types of sight lines in the drawing. Existing sight lines can alsobe edited and removed. Sight line analysis is important for determining safetyconstraints in a roundabout.
REFINE ROUNDABOUT GEOMETRY
Initial theoretical outer edges of bypass lanes, turning lanes, and inscribed circlegeometry of the roundabout based on the vehicle’s swept path movements(clothoid spirals) can be created and refined to produce ideal line and arcgeometry as well as curve tables for construction and survey purposes.
EFFICIENT DESIGN EDITING
Easily create new roundabout iterations by editing previously generatedroundabouts to check different placement positions and design parameters.You can quickly see how changes in the geometry affect operational safetyand performance. TORUS editing features all the same controls and abilitiesfound in the Generate Roundabout tool.
EXPAND YOUR CIRCLE OF PRODUCTIVITY
ADVANCED SIGHT LINE EVALUATION
Evaluate critical sight lines between approach legs or for circuitry vehiclemovements to ensure adequate stopping, merging, and driver decisiondistances. Sight line assessments include Approach to Crosswalk, Approachto Yield Line, Yield to Crosswalk, Junction and Circulatory based on criteria forapproach speed, perception-brake time, deceleration, and critical gap.
>> Select and view different roundabout iterations from your saved files for projectdecision making and client review. Each roundabout design can have its owndesign symbol and independent set of iterations.
>> The roundabout design is instantly updated when edits are made to differentelements such as approach lanes and exit radius.

ROUNDABOUT DESIGN FEATURES
• Modify the approach leg reference geometry (e.g. lines, arcs, polylines/complexchains) using grip-points to test vehicle entry deflection and the correspondingeffects on fastest path, entry angle, and sight lines
• Generate single or multilane roundabouts based on design vehicle paths andclearance offsets
• Control roundabout size using the inscribed circle or central island diameter• Drag and position roundabouts in the design to assess optimal locations• Specify design parameters for approach legs (offsets, widths, bypass lanes,
entry/exit lanes, crosswalk sizes, splitter islands, and taper angles)• Edit leg properties such as crosswalk location, taper angle,
and entry/intermediate/exit path radius• Modify inscribed circle diameter, central island diameter, and circulatory width• Calculate and draw lorry apron width based on design vehicle movements or
user-defined specifications• Set offset geometry for inscribed circle diameter, circulating roadway, footprint,
and bypass lanes• Calculate the vehicle drive paths for path overlap analysis and draw the entry
and exit paths
ROUNDABOUT SURFACE GRADING
• Draw grading model to represent crown alignments and cross slopes• Ensure drainage patterns work within the roundabout layout
(e.g. slope away from the central island)• Check grading values for: Maximum Cross-Slope percentage; Minimum
Alignment Slope percentage; and Contour Line Resolution value• Add vertical curves to an alignment by K-Value with the Edit Vertical Profile Tool• Add VPI (Vertical Point of Interest) to alignments• Export grading model as LandXML to be imported into vertical CAD platforms
ADVANCED GEOMETRIC CONTROL
• Use polylines and complex chains as reference alignment geometry in thedesign of complex approach legs defined by curvilinear geometry
• Employ vehicle speed reduction treatment using successive curves on approaches• Generate edges based on design vehicle tyre tracks, offsets and radii as specified
in the design guidelines• Refine complex edge geometry into lines and arcs, then output survey data to
a curve table• Replace TORUS refined edges with user-defined polylines/complex chains
FASTEST PATH EVALUATION
• Generate a vehicle’s fastest path through a roundabout for design analysisand checking purposes
• Calculate and display fastest paths based on theoretical edges and refinededges of a TORUS generated roundabout
• Apply fastest path design values for leg and circulatory superelevation,speed differences and offsets from central island, median, and edges
SIGHT LINE ANALYSIS
• Evaluate critical sight lines between approach legs and roundabout features.• Insert sight lines assessments for: Approach to Crosswalk;
Approach to Yield Line; Yield to Crosswalk; Junction; Circulatory;Angle of Visibility
• Add a new sight line assessment into an existing roundabout design• Define sight line design values for speed, approaches and driver’s
eye location
VEHICLE MOVEMENT FEATURES
• Generate standard design vehicle path movements between approaches• Review and display previously generated vehicle movements and adjust
entry/exit approach leg, driving lane, and standard design vehicle• Vehicle movements updated dynamically when design edits are applied
to a roundabout
PRESENTATION FEATURES
• Manage vehicle animations with Transoft Solutions’ presentation software,InVision, to create timed and sequenced events. Files can be exported intoselected video formats for playback on any PC with popular video players
REPORTING FEATURES
• Area Estimation Report - Generate a report that shows the approximateland area and perimeter used by a selected roundabout
• Summary Report - Create a report with all required design information.Data can be exported to text and CSV formats
