The future safety of maritime transportation in the United States-a major factor in the nation's international trade and economic well-being-will depend heavily on the quality of port and waterways information systems. Many U.S. ports and waterways lack adequate information services, although certain elements of advanced systems are now available in some locations. Barriers to improvements in information systems include the division of responsibilities for waterways management among multiple agencies at all levels of government, a lack of coordination among the federal agencies responsible for waterways management, inadequate budgets for some critical maritime programs, the high costs of some specialized technologies, stakeholder opposition to user fees, limited access to certain key data, the incompatibility of many independently developed systems, and the absence of standards for some attractive technologies. In this report, the second phase of a three-year study by the Committee on Maritime Advanced Information Systems of the National Research Council, a strategy is presented for overcoming the major barriers and deficiencies and providing a minimum level of maritime safety information nationwide. In this phase of the study, the committee concentrated on maritime information systems that promote safety, which is the area of greatest need. The committee did not examine in detail the relationship between navigation safety and maritime transportation efficiency or evaluate information systems that promote efficiency; the committee believes, however, that these issues deserve further attention.

The United States is a maritime nation. From its origin as 13 former colonies to its place as the pre-eminent world power today, our Nation's success has been dependent on our coastal ports and inland waterways to conduct trade. Recognising the importance of transportation to trade, the Nation had made a strong intergenerational commitment to develop its transportation networks. These networks of highways, railways and inland waterways connect the interior of our country to our ports, which connect us to the rest of the world. These transportation networks have contributed to our success by providing a cost-efficient and environmentally sustainable means to transport large quantities of cargo over long distances and across oceans, keeping this Nation competitive in world trade. This book provides an analysis of the broad challenges and opportunities presented by the increasing deployment of post-Panamax vessels and outlines options on how Congress could address the port and inland waterway infrastructure modernisation issues needed to accommodate those vessels.
