Timely, comprehensive, and high-quality data on freight shipments, flows, and services can improve decision making of public infrastructure operators and planners as well as private sector carriers and shippers. The private sector is the primary producer of freight data and the public sector is the key consumer. Sharing of freight data between the private and public sectors has not occurred to the extent that practitioners had hoped. Reasons for this largely center on private sector proprietary concerns with sharing their data, as well as with the public sectors nescience to fully appreciate and adjust their data goals and needs to these concerns. The transportation community and TRB in particular have been working to improve freight data availability to users. As an outgrowth of various TRB and FHWA workshops and research studies, TRB initiated NCFRP 31, a project that involved the development and refinement of guidelines for data sharing. The project reviewed past and current efforts in freight transportation to share data and looked in detail at selected data sharing projects. This project covered freight data sharing activities in North America, as well as outside the United States and Canada, and involved land as well as waterways projects. |
