The process studied is that a merging with (or crossing) a single lane of major road traffic which has absolute priority over minor road vehicles. Headways on the major road have an arbitrary distribution and may be correlated. The maximum rate of absorption of merging vehicles for which the queue on the minor road may be considered to be infinite is investigated. Each minor road vehicle samples minimum acceptance levels from the same distribution until confronted with a sufficiently long opportunity to cross. After a departure, the next vehicle moves up, the time taken to do so being sampled from another arbitrary distribution. The maximum rate of absorption is synonymous with the mean absorption rate in the case of an infinite queue, and upper and lower bounds for this mean absorption rate are found. By imposing a restriction which real traffic should often satisfy, or nearly satisfy, the upper bound is found to be exact. Simple results for a Poisson major road are derived.
