Abstract

A capacity analysis of Latham Circle, a traffic circle in New York State, is presented. From videotapes, 1-min observations of entry flow are correlated with simultaneous observations of circulating flow. Values for the minimum acceptable gap, minimum circulating headway, move-up time, and so forth are calculated so that the predictions of various capacity equations, established abroad, can be compared and contrasted with the traffic circle's performance. It is found not only that the observed parameter values closely match those from abroad, but also that several of the equations appear to provide reasonable estimates of capacity. Because of this, these relationships may be adaptable to U.S. conditions without significant recalibration or reformulation.
