A video from a post from the Autodesk Transportation blog by Jeff Bartels.
This is a 11 part video list that covers in-depth and detail an FDOT approach to intersections for multi-lane roadways.
Employs multiple corridors and manual Superelevation control to manage changing lane slopes on tangents. Does not employ Intersections.
Covers crown change issues in divided highways. Multiple surface paste.
This listing also appears in the FDOT YouTube channel.
