Calibration of Road Capacity

Both HCM and geometric models include approach and exit road capacity calibration.

Calibration of Approach Road and Exit Road Capacity

The capacity of the Approach Road (V wide) and the Exit Road (Vx wide) is approximately estimated from V and Vx and the Environment setting.

However, local conditions may be different and values superseding the defaults can be entered using the Calibration table above. If the calibration is set to 0 the default is used.
