Difference between capacity and saturation

[Blu1913]

Are capacity and saturation interchangable or are they completely separate. If they are separate, what is a clear definition for them.

Thanks.

Capacity is the maximum rate of flow for the subject lane group that may pass through the intersection under prevailing traffic, roadway and signalization conditons.

Capacity = saturation flow rate*( effective green ratio)

V/C is the degree of saturation/volume to capacity ratio

Saturation flow is the total maximum flow rate when 100% o fthe green time is available.
