| Transition Type | Description | Typical Use Case | | :--- | :--- | :--- | | | Straight-line transition between two values. | Simple, constant-rate lane widening or slope change. | | Cubic In/Out | "S"-curve transitions, where the rate of change starts slowly, speeds up, and then slows down again. | Cosmetic transitions or aesthetic road widening. | | Parabolic In/Out | Parabolic-shaped transition based on a parabola equation. | High-speed roadway transitions requiring vertical curve blending. | | Reverse Parabolic | Inverse parabolic transition. | | | Bay Taper | Specific taper for bus bays or acceleration lanes. | Bus bay lane widening, turn lane tapers. | This release introduces a comprehensive US Imperial rail
Perhaps the most transformative updates in the 2023 cycle are within the modeling environment. | Simple, constant-rate lane widening or slope change
Pressure networks see continuous improvement in every release, but 2023 brought vital stability and design path flexibility. PVIs and Geometry Editing
Watch the optimization engine work in real-time with graphs tracking volume balances.
The software now features enhanced modeling capabilities for complex rail switches, allowing for more precise layout and alignment of switches.
