| 摘要： | This study identified freight data uses, needs, and gaps, both nationally and in the state of Washington. Specific recommendations for providing the needed data and data generating processes include the following: • Phase I: Identification of Data Gaps, Needs, and Uses (Time-frame: current and ongoing). An ongoing inventory of available freight data, relative to identified freight data needs, should be performed throughout the state and region. This process may be incorporated into the expected activities/duties proposed in these recommendations. Phase II: Librarian/Educator, Resource to Manage Freight Data Warehouse (Time-frame: within six months). This individual or resource is a “data source” for the state; a contact for all agencies and businesses using transportation flow and operational data; and a participant in discussions as freight data needs arise in the state. Phase III: Freight Manager, Technical Resource (Time-frame: within one year). The Freight Database Manager will design/develop and maintain the freight data warehouse for the Washington State Department of Transportation (WSDOT). |
