Intermodal Freight Congestion
The TRAC seeks to target investment toward mitigation the existing intermodal freight capacity constraints, using a congestion scales that is analogous with roadway volume-to-capacity ratio. Just as roads have a capacity based on speed limits, type of roadway, and number of lanes, water and rail facilities have similar capacity measures. Congestion ratio can be calculated for intermodal facilities based on the volume of freight they carry or lists made compared with their capacity.
