The invention discloses a wireless sensor network-based unattended intelligent container truck traffic monitoring system. The monitoring system consists of a north wireless sensing area, a south wireless sensing area, a west wireless sensing area and an east wireless sensing area which are used for monitoring the operation conditions of container trucks running in opposite directions on various roads; and a traffic road junction center is provided with a north indicator (N), a south indicator (S), a west indicator (W) and an east indicator (E) which are opposite to the wireless sensing areas and used for sending traffic scheduling instructions to the container trucks in the corresponding direction. By a wireless sensor network and multi-sensor collaboration technology, the operation conditions of the container trucks can be automatically determined; and vehicle scheduling instructions are sent in real time according to the requirements of container truck loading and unloading operation and scheduling operation, so that the operation order of vehicles in a port area is fundamentally improved, the operation efficiency of the container trucks is improved, and the aims of saving energy and reducing emission are fulfilled.
