N2  - This paper illustrates the effects of signal queues on traffic operations at closely spaced intersections. The proposed approach is to relate the size of a downstream queue to both the physical link length and the saturation flow rate at the upstream signal. Queue interaction effects occur when traffic volumes approach, but do not necessarily exceed, capacity. Queue interaction results in lower system output, added delay to the upstream link, and high probability of spillback. The method also demonstrates the utility of signal-based methods in overcoming some of the detrimental aspects of queue interaction. In particular, the use of simultaneous offset settings and metering policies at the upstream signal are found to be very effective.     <p>Language: en</p>
