Abstract

A procedure that predicts morning inbound and evening outbound queuing delays on express highway facilities in downtown areas is discussed. The procedure is based on the relationships among hourly traffic capacities at bottleneck points, daily volumes at those points, and associated queues and delays. The need for such a procedure arose from difficulties in using traffic assignment or other existing analysis techniques to predict queues and delays associated with alternative highway plans. Empirical delay data for developing the procedure came from nearly 600 speed runs conducted on the express highway system in and near downtown Boston. Fouteen queuing and potential queuing situations were analyzed. The relationships derived appear to be generalizable, and the specific results from the Boston area should apply to other urban areas of comparable size. (A)
