Functional ClassificationThe facility must represent the appropriate balance between access and mobility for its intended purpose. The functional classification system developed by the Federal Highway Administration (FHWA) reflects the degree of local access and regional connectivity a roadway provides. The level of access control should reflect the official functional classification as well as the actual role that the roadway serves, which may vary along a roadway corridor. While there may be substantial flexibility in defining the level of access control for new roadways, the options may be substantially more complex or limited on projects that are modifying existing roadways. Roadway UsersMDOT values the needs of all of its roadway users, including cars, trucks, bicyclists, and pedestrians. All user needs both along a roadway and across it should be considered.
Roadway Capacity and OperationsLevel of Service indicates general traffic capacity needs:
Adding capacity that creates failing conditions upstream, or downstream, of proposed improvements should be avoided. Other performance measures may be needed to develop solutions that address specific project needs.
