Evaluates the roundabout to calculate and draw the fastest paths. The fastest paths are the vehicle movements through the roundabout at the fastest speed possible, i.e. achieving the largest possible radii in the roundabout (for more information on the fastest paths, see Overview -> Fastest Path).

Evaluate the fastest path for a:

• TORUS generated roundabout
• User-Drawn roundabout
• Adaptive roundabout

For examples of how the Evaluate Fastest Path tool works, please play the Evaluate Fastest Path and Fastest Path on User-Drawn Roundabout tutorials (for information on how to play a tutorial, see Tutorials -> Play).

Note: The Evaluate Fastest Path tool is not applicable to roundabouts generated using a German regional design guideline (see Design Guidelines).
