NEXUS Intersections

State-of-the-Art Software for Roadway Intersection Planning and Design

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.

Benefits & Advantages


NEXUS allows the engineer to evaluate and monitor the performance of the entire intersection design as changes are made. The key benefit to the user is the speed of generating the geometry and surface drainage in a single tool.
NEXUS Overview Video
NEXUS was developed to give engineers the ability to quickly and efficiently create intersection layouts with pre-generated templates and sophisticated editing tools that continually update the intersection as design changes are made.

NEXUS Intersections Features

Visualize different design alternatives faster by using pre-defined leg templates. With over 450 templates to choose from, engineers can easily filter through the entire library to work with applicable templates.
NEXUS can now generate Autodesk® AutoCAD® Civil 3D® surfaces, vertical, and horizontal alignments. Civil 3D objects (such as corridors) are updated dynamically using the NEXUS grading model.
