Abstract: United States economy relies heavily on Marine Transportation Systems (MTS) to import essential raw materials and export products through ports and channels. Development in cargo and freight transshipment, along with the increase in the size of vessels and physical waterway restrictions, leave vessels with long waiting times and consequent economic problems. To assess and control the waterway congestion and to find bottlenecks or congested areas, it is necessary to measure and quantify congestion. One of the most solid sources of data in studying MTS traffic congestion is the automatic identification system (AIS) data. In this presentation we will present an AIS-based data analytic approach to quantify the indices for a whole waterway (macro level) as well as smaller segments (micro level), and apply the methodology on Houston Ship Channel (HSC) AIS data as a case study and present the indices in both average and real-time values, where the results are analyzed and visualized through maps, time-lapses, and colormap charts.
