This study analyzes vessel traffic characteristics in Yangtze River Estuary water areas. Real-time vessel automatic identification system (AIS) data, with about thirty million records, were collected from Lloyd’s Marine Intelligence Unit database. Cargo ships made up the largest proportion (64.17%) of vessel traffic in Yangtze River Estuary water areas. Passengers and fishing ships accounted for a small proportion, only 1.63%. Analysis suggested that special attention should be paid to containerships because of their larger draughts. The spatial distribution of vessel traffic shows that westbound traffic flow is slightly less than eastbound and vessel traffic density in Area A is the greatest. Vessel speeds in four areas including Areas A, B, C, and F follow composite distributions best. Vessels in Areas A, B, C, D, and E are found to have higher collision potential than other areas. Speed limit and passage notes are recommended to assure the safe navigation.
