Ferry Landing Design Criteria II: Vessel Tracking Methods for Ferry Landing Design

Description: Methods for recording the approach path and approach velocity of berthing vessels are developed and tested. Methods include video camera observations from shore, video camera observations of the radar screen, and global positioning system (GPS) tracking. The methods are tested on the Washington State Ferry Edmonds to Kingston crossing. The video methods are useful for preliminary studies to obtain approximate results and familiarize investigators with the berthing process. The GPS records provide more precise results with less data reduction effort than other methods. Twenty-four berthing maneuvers are recorded. Analysis of the GPS record shows a consistent pattern of velocity reductions as the vessels nears the landing structure.
