High-occupancy-vehicle systems and freeway operations. A peer reviewed publication of the Transportation Research Board TRB.

The papers in this volume were presented at the 1994 Annual Meeting of the Transportation Research Board. The papers cover a wide range of problems reflecting the concerns of both the theoreticians and the practitioners. These specific areas of traffic operations are receiving considerable attention because of the emphasis on intelligent vehicle-highway systems (IVHS), provisions of the Intermodel Surface Transportation Efficiency Act (ISTEA), implications of the Clean Air Act Amendments, ever-increasing traffic congestion, and recognition of the importance of incident management for reducing nonrecurring traffic congestion. Also attention is given to HOV lane evaluation, use of computer simulation models for HOV applications, HOV strategies and priority treatments on toll facilities and at ramp meters, conversion of mixed-use freeway lanes to HOV and HOV marketing to build a constituency. Finally, attention is given to ramp metering and increasing freeway ramp capacity, freeway service patrols, and design of emergency parking for restriped urban freeways.
