What are some types of Fast Lanes?

The Federal Highway Administration (FHWA) defines managed lanes as offering “enhanced operational conditions within separated lanes, which result in outcomes such as greater efficiency free-flow speeds or reduced congestion.”
High Occupancy Vehicle (HOV) lanes are reserved for buses, carpools and vanpools. HOV lanes currently exist in the Charlotte region on I-77 between I-85 and Exit 23 in Huntersville.

HOT (High Occupancy Toll) lanes allow buses, carpools and vanpools to travel at no-charge reserved lanes, while single occupant vehicles must pay a toll.

Special Use lanes are express lanes with limited entrances and exits, bus-only lanes, and truck-only lanes

Why consider Fast Lanes?  
Travel demand is growing faster than population.
Rush-hour congestion is expanding into more hours.
Travel patterns are diverse.
Travel distances are increasing as people choose housing farther from work.

NCDOT estimates a $65 billion gap between future anticipated revenues and the actual cost of building, operating and maintaining roads statewide.

Fast Lanes are long-term, sustainable facilities that safely provide travel times savings and trip reliability.
