Corridor modeling—the backbone of road design—saw major upgrades. The software improved how assemblies (cross-sections) interacted with targets. This allowed for more complex road designs, including variable lane widths and dynamic daylighting (slopes that adjust to the terrain). These enhancements allowed engineers to model complex intersections and interchanges with far less frustration than previous iterations. While you should not install it on a
