NEXUS will change the way engineers and designers plan and design roadway intersections. As each design component is related and dependent on each other, NEXUS allows you to evaluate and monitor the performance of the entire design as changes are made, speeding up the development of intersection geometry and surface draining in one single, and efficient software solution.
ADVANCED INTERSECTION DESIGNING
Quickly and easily generate intersection layouts with schematic pavement markings and edges using one or a combination of methods including: defining the schematic lane configuration; importing capacity data; selecting a pre-defined leg template; or using an intersection template. Key elements are all included in the first cut layout.
DYNAMIC UPDATES AND EDITS TO THE INTERSECTION
Edit and refine the basic intersection design right from the initial layout. Make changes to the alignments of legs, lanes, and lane configurations as you design. Use powerful tools to add and edit individual intersection components including: bike lanes, crosswalks, vehicle storage lengths, auxiliary lanes, stop bars, median and corner islands.
WORK WITH VEHICLE CAPACITY CONDITIONS
NEXUS lets you initialize a design based on capacity data by updating the intersection from capacity conditions imported from HCS (Highway Capacity Software) data or other manually inputted information from other traffic analysis software.
DESIGN INTERSECTION CORNER GEOMETRY
Dynamically configure corner geometry types for Arc, Biarc, and Triarc. Unique to NEXUS, you also can design corner geometry with the patent pending Vehicle Envelope Method using vehicle turning movement to govern the slip lane edge of the corner island envelope ensuring that the design works for the specified vehicle.
DESIGN INTERSECTION CONTROL RADIUS
Define the control radius to set an intersection’s median opening length. You can also design with the patent pending Vehicle Envelope Method by using a vehicle swept path from a turning simulation. Design vehicle movements can also be generated to govern the nose median position and to check issues with opposing left turn movements.
EVALUATE VEHICLE MOVEMENT IN THE INTERSECTION
You can easily evaluate vehicle movements by displaying AutoTURN compatible design and checking vehicle simulations within a NEXUS intersection. By setting the turning radius, speed, entry and exit lanes, and the design vehicle – movements are easily performed for checking your designs.
EVALUATE DRIVER SIGHT LINES FOR SAFETY
Quickly assess the impact of sight lines on an intersection for right-of-way or landscaping based on sight triangles, checking left turns on major streets, and at critical points. You can generate sight triangles by manually inputting specified stopping distances or use a convenient lookup tool for AASHTO 2004 Cases A, B, and C.
CONFLICT POINT ANALYSIS FOR SAFER INTERSECTIONS
With NEXUS, you can determine the number of different conflict points in an intersection where vehicle paths cross, merge, and even diverge. From the conflict point diagram, you can easily see where the potential areas of accidents could occur helping you assess the safety performance of your intersection.
DESIGN GRADING IN 3 DIMENSIONS
With NEXUS, you can develop a grading model and establish the drainage pattern in 3D even in base CAD applications. Vertical profiles provide immediate feedback on cross slopes and alignment slopes. The developed alignments can be exported to a LandXML format for transitions to vertical CAD products.
CONTROL IT ALL WITH DESIGN MANAGER
The NEXUS Design Manager feature allows you to save, manage, recall, and compare multiple intersection design iterations within a single CAD drawing without the need for CAD level and layer management. Now in the design process, the preliminary design moves quicker on to the approval and final design stages.
INTERSECTION REPORTING TOOLS
With NEXUS, you can create, compare, and share your data from a previously generated intersection design with an Intersection Summary Report detailing key design elements and a Capacity Conditions Report with information on intersections that can be exported to a .txt format file.
