About Optimizing the Design of Roads

Corridor Optimization and Profile Optimization produce multiple designs that can be compared for cost and environmental impact.

You can submit multiple optimization jobs, each using a different combination of parameters, which include:

  • Design speed
  • Maximum grade
  • Mimimum grade for drainage
  • How to grade roadside cut slopes and fill slopes (cross-slopes)
  • When to use roads, bridges, and tunnels
  • PVI frequency and minimum PVI spacing
  • PVIs that must remain at a fixed station and elevation
  • Areas to be avoided
  • Placement and capacity of borrow and waste pits

Optimization jobs are processed in the cloud and return existing ground profiles along the centerline of the road. The process detects when the profile crosses other roads and creates intersections. An algorithm detects water crossings and computes the cost of placing bridges.

Each optimization job returns a PDF report that lists details about the centerline profile, cross sections, and construction and earthwork costs. You can import the optimized road into your model as a proposal, and then compare various proposals to determine which is the best solution for your project.

We'll notify you by email when each optimization job is ready. You can also see the status of each job on the Job Monitor.
