We developed a technical framework allowing the use of "big data" derived from the Automatic Identification System(AIS, an automatic ship-tracking network) for two purposes: the accurate mapping of oil tanker trajectories and the creation of heat maps showing the relative use of oil tanker routes and marine shipping chokepoints. We then applied these methods to 1.5 billion AIS records collected within the MSR in 2014 to statistically identify and analyze busy routes, areas, and chokepoints in this strategic region. Our results demonstrate that the proposed framework can provide an effective analysis of oil movements based on large-scale AIS datasets, helping researchers and policy makers better understand the footprint and strategic implications of maritime oil transportation in the MSR region.展开更多

Although the construction of the new maritime silk road has its？ endogenous logic and justified considerations, it will encounter various challenges and difficulties. In order to achieve the strategic goal of setting up a community？ of common interest and？ destiny with the relative countries, the ＂Maritime Silk Road＂ program has to be advanced cautiously with the principles of wide consultation, joint contribution and shared benefits.展开更多
