In 2014 Cambridge Systematics, Inc. and Greenman-Pedersen, Inc. (the “research team”) undertook research on alternative methodologies to count and classify vessels on New Jersey’s Marine Transportation System. During the late summer of 2017, the research team undertook a third phase of data collection with a goal of continuing to test field data collection methodologies under a wider range of field conditions and collect additional vessel data. Another objective of the third phase of research was to collect additional field data on state-maintained waterways.
