Abstract

The paper examines the effects of slow moving obstructions on a traffic stream. The main determinants of these effects identified are: the maximum rate at which a queue held back by the moving bottleneck discharges; and the density of the queue for a given discharge rate. All moving bottleneck theories are described, and the experimental basis for the new theory is presented. A case study of a steadily moving bottleneck on Freeway I-880 in Oakland, California, identified and characterized from loop detector data, including the behavior of the traffic stream around it, is presented. Also described are two batteries of floating vehicle experiments involving a slow test vehicle that revealed a relationship between maximum passing rate and bottleneck speed for one lane obstructions in two- and three-lane highways. A possible extension of the theory is detailed.
