The calculation is performed according to either HCM 2010, HCM 6th Edition (Fundamentals: Roundabouts according to the HCM method ), HCM 7th Edition (Fundamentals: Roundabouts according to the HCM method ) or TRL/Kimber (Fundamentals: Roundabouts according to the TRL/Kimber method).
1. Make sure that the values of the input attributes are correct at the nodes with control type Roundabout.
- Input attributes for calculation based on HCM (Fundamentals: Roundabouts according to the HCM method )
- Input attributes for calculation based on TRL/Kimber (Fundamentals: Roundabouts according to the TRL/Kimber method)
2. Check and adjust the parameters on the Roundabout page.
