Potential capacity at an unsignalized intersection can be described as a conditional expectation from which the capacity equations for the most common headway distributions are easily obtained and each term in the equation finds an interpretation. The movement capacity of Rank 3 streams is adjusted for both Rank 2 queues and the modified headway distribution and lower flow rates during the free-departure periods of Rank 2 streams. The resulting movement capacities are higher than those of the Highway Capacity Manual (HCM 2000), especially at low major-stream flow rates. The Rank 4 stream adjustment factors are shown to be multiplicative even across streams of different ranks. The extra correction in HCM 2000 is, in the light of this theory, unnecessary.
