In the middle of the 19th century, people began to formulate some rules for ship navigation and set up some lighthouses, navigation marks and other signals at the dock. This caused the navigation rules and visual traffic signals to become the original form of the modern ship traffic management system (VTMS). With the rapid development of water transport industry, the number of ships has increased unprecedentedly. The large-scale and high-speed ship has greatly increased the water required for navigation and berthing. This has made the traffic congestion in limited waters more unprecedented and increased the difficulty of manoeuvring. A security system is required. In addition, the air crash accident accelerated the formulation of traffic regulations and the construction of the system. For example, in March 1967, 110,000 tons of Liberian tankers hit the rocks on the British coast, causing 80,000 tons of oil spillage, seriously polluting the English Channel, causing The shock of countries, especially Britain and France, as an opportunity, the international watercourse has implemented a separate channel system. The collision of two tankers in the San Francisco Bay in 1971 caused serious pollution in the Gulf. It prompted the United States to develop the "Port and Waterway Safety Law" and established the San Francisco Experimental Ship Traffic System the following year. The development of communication, radar, radar data processing technology and computer technology has also provided technically realistic possibilities for the development and improvement of VTMS.

In 1948, the Port of Liverpool in the United Kingdom installed the world's first port radar and used ship-to-shore communications equipment to guide ships sailing in the fog. In 1972, the United States first applied computer technology to traditional port radars, established the San Francisco experimental ship traffic system, and laid the technical foundation for the establishment of the VTMS advanced surveillance system. In February 1977, the Tokyo Bay VTMS with radar data processing and traffic data processing functions was officially put into operation, forming the basic pattern of the VTMS automated advanced monitoring system. Since then, the development of the ship traffic management system is mainly reflected in the technical improvement and improvement. As of the mid-1980s, there were more than 150 VTMSs in the world, which played an important role in ship transportation and traffic management.
