This Transportation Research Board standing committee is concerned with the evolving role of high-occupancy vehicle, high-occupancy toll, and managed lanes in response to the challenges of congestion, energy consumption, and climate change. The committee examines methods for enhancing person throughput, energy conservation, air quality, and user choices and safety through the optimization of preferential lanes, priority treatments, and other supporting systems for bus transit, carpooling, and vanpooling. The committee’s activities focus on the planning, design, operation, pricing, and evaluation of preferential lane facilities and on the development, validation, and dissemination of theoretical, experimental, and applied research related to preferential lanes.

The Transportation Research Board (TRB) 91st Annual Meeting will be held in Washington, D.C. at the Washington Marriott Wardman Park, Omni Shoreham, and Washington Hilton hotels.
