| | Managed Lanes, November/December 2004 Public Roads |
 | | Traditionally, agencies have used various lane management strategies on freeway facilities—including reversible flow lanes, express lanes, HOV lanes, truck lanes, and toll facilities—in a manner that typically does not involve any active management or variation in how traffic is controlled in response to changing conditions. |
 | | Because HOV lanes carry vehicles with a higher number of occupants, they have the potential to move more people in a smaller number of vehicles, in comparison to the adjoining general purpose travel lanes, during congested travel periods. |
 | | HOV lanes alone do not qualify as managed lanes, but when coupled with another operational strategy (such as pricing), or if real-time changes are made in their operation in response to changing conditions, then they would be considered a managed lane. |
