The Priority Highway Improvement Corridors (PHIC) Map
identifies several roadway segments where travel demand will exceed the hourly capacity of the facilities. In those cases, congestion (lack of mobility) is expected to occur. Where the demand far exceeds the hourly capacity, the duration of this congestion will be much longer.
The concept of PHIC is to apply the entire tool box of demand management, access management, transit, pedestrian safety, and geometric improvement strategies to accommodate the anticipated travel demand.
