Road and Junction Designers


Design and plan the operation of safe road junctions


Saves you 65% of the design costs involved in manual processes or other CAD programs

Traffic Management software


NEXUS® is the ultimate intersection design solution for new construction and rehabilitation projects offering vehicle operations, geometric design, and safety performances together in one comprehensive package. With 65% savings in overall design costs, NEXUS allows for the creation and evaluation of intersection concepts in a fraction of the time compared to traditional or manual computer-aided drafting and designing.

Using the Vehicle Envelope Method® (U.S. Patent No. 8,650,004) of design, NEXUS incorporates all the key elements in the intersection design process including design vehicles, capacity conditions, sight lines, conflict points, and conceptual grading – providing instant feedback so engineers can quickly and easily produce highly effective and safety oriented intersection layouts.

What People are Saying

Huge time savings in developing initial design options. I like the fact that vehicle paths are tied to intersection geometry

George Koumoutsidis, Stantec INC

NEXUS Highlights

  • Dynamically generate junctions using any or a combination of 4 different methods
  • The patent pending Vehicle Envelope Method generates junction geometry
  • Ability to draw: Conflict Points; Tally of Crossing Points; Merge Points; Diverge Points; and Total Points.


  • Junction Geometry Generation. Ability to define bay taper ratio and auxiliary taper type, draw roundabouts, and add bicycle lanes
  • With Sight Lines Checking you can toggle the display on or off for a selected junction design. Generate sight triangles for turns with user-defined stopping sight distances
  • Ability to create a 3D grading model of a junction. Draw basic contour lines based on the contour intervals for evaluating drainage patterns.
