Abstract
Currently, according to regulations, inland waterway vessels are only allowed to operate on coastal routes issued by the Ministry of Transport of Vietnam. However, most of these vessels often operate outside the permitted routes to save time and fuel,... and in order to avoid detection, these vessels often turn off the AIS device (AIS - Automatic Indentification system), move into the blind zone of radar,… The article proposes a solution to monitor inland waterway vessel operating on coastal routes basing on Radar/AIS data to enhance marine safety on Vietnam's coastal shipping route.
