Express lanes
From Wikipedia, the free encyclopedia
Express Lanes are according to FHWA "A lane or set of lanes physically separated or barriered from the general-purpose capacity provided within major roadway corridors. Express lane access is managed by limiting the number of entranced and exit points to the facility. Express lanes may be operated as reversible flow facilities or bi-directional facilities."[1]
Express lanes are different than local-express lane systems in that local-express lanes are generally limited to only having access to the general-purpose freeway lanes, while express lanes limit the number of interchanges they interact with, and have little, if any, access to the general-purpose lanes, save for the termini of the lanes. The interchanges that interact with reversible express lanes are specially constructed to accept traffic flow in either direction. Express lanes extend the traditional concept of reversible lanes because the express lanes are separated from other travel lanes, either by grade separation or by immovable barriers (like Jersey barriers).
