The papers in this Record are concerned with disabled vehicles and other incidents that temporarily reduce the capacity of freeways. They are of special interest to all concerned with traffic operations in arterial corridors. The publication includes investigation of the feasibility of using the traffic flow information from on-line, computer-based surveillance systems to detect incidents on the John Lodge Freeway in Detroit and on the Gulf Freeway in Houston; a final report on the use of Citizens Band radio to provide a highway communications service in Ohio; a discussion of detector reliability with reference to a motorist information system on the Gulf Freeway in Houston; a description of a Kalman filtering methodology for the estimation of traffic densities on multilane roadways, tested by using aerial photography data; an examination of the phenomenon of the discontinuous drop in flow that occurs as traffic density increases; a discussion of a method for smoothing flow during congestion; and a discussion of the optimization techniques that have been developed and applied for evaluating freeway operational improvements such as redesign or ramp control strategies.
