The 18 papers in this volume are related by their focus on highway capacity, quality of service, traffic flow measurements, and traffic flow theory. The papers cover a wide range of problems reflecting the concerns of both practitioners and theoreticians. Highway capacity is receiving considerable attention as a result of the research effort toward producing the next edition of the 'Highway Capacity Manual', to be published about 2000. The initial papers in this Record examine the issue of capacity as it related to two-lane highways, freeway bottlenecks, freeway weaving sections, stop-controlled intersections, traffic circles, left turns, and delay at signalized intersections. Traffic flow theory, modeling, and control applications are also examined in papers on oversaturated conditions and traffic control, speed estimation and catastrophe theory, headway probability distribution, and simulation modeling of school congestion. Whether the reader is a traffic engineer trying to determine the capacity and level of service of two-lane highways or a traffic flow theoretician pondering the vagaries of traffic flow equations, the papers in this Record should be both interesting and informative.
