2. Background
Capability Statement – The United States Army Corps of Engineers (USACE) will have accurate, readily available historic and current waterway travel time statistics.
Value Statement – The travel time statistics will enable the USACE to monitor the performance of the waterways, to make informed operations & maintenance decisions, and to provide voyage planning information to stakeholders so that they can optimize their waterway usage.

3. Automatic Identification system (AIS)
AIS is a real-time shipboard broadcast system 
Information included in broadcasts:
Vessel identification
Vessel characteristics
Time stamp
Location (Lat/Lon)
Speed over ground
Course over ground
Heading
Broadcasts are at discrete intervals
Carriage requirements are set by federal regulations
File Name

4. method Define trip origin, destination, and time period of study
Acquire AIS data
Segment the waterway between the origin and destination into links
Identify vessel transits and determine their travel times
Estimate link travel time statistics
Estimate origin – destination statistics
