Impediments focus on landside access to ports.
Some ports fell into more than one category. The goal is to broaden the scope of the data to be representative of all U.S. ports, i.e. deep and shallow draft, coastal and inland waterways. The data is also expected to reflect both landside and waterside impediments. Currently, the responsible organization is designing a survey instrument to obtain detailed information at the port and terminal level directly from the port. The instrument will require OMB approval prior to implementation.
