unmanned vehicles are an essential part of the future smart ports. The rapid development of technologies，such as automatics driving，artificial intelligence and 5G，make the realization of unmanned vehicles for ports has become possible. This report focuses on the development of unmanned vehicles using in port，the characteristics of traditional container tractors，AGV tractors and IGV tractors，the application of 5G technology in port unmanned vehicles，and the key technology and application research progress under the scene are reviewed. The report looks forward to the future development prospects of port unmanned vehicles，it is believed that the combination of port unmanned vehicles and 5G+AI+automatic driving technologies to form an intelligent system with comprehensive perception，ubiquitous interconnection，and port-vehicle collaboration is an important technological development direction in the future.
