Transfer system

Regarding a transfer system that includes a plurality of transfer vehicles that transfer articles, the present invention realizes technology that can alleviate congestion that is caused due to the travel speed of a specific vehicle that performs a specific task being lower than that of the transfer vehicles. The transfer system includes a plurality of transfer vehicles that travel on a transfer path to transfer articles, and the transfer system further includes: a specific vehicle that performs a specific task while travelling on the transfer path at a speed lower than that of the transfer vehicles; and a congestion determination unit that determines whether or not there is congestion behind the specific vehicle. Upon the congestion determination unit determining that there is congestion, the specific vehicle suspends the task and performs evacuation travel to evacuate from a task point at which the specific vehicle was performing the task.
