Abstract
In a case where a travel permission request regarding a queuing zone for a first unmanned vehicle stopped in a queuing zone is received, on the basis of a time length taken for the first unmanned vehicle arriving at a deceleration start position and a time length taken for a second unmanned vehicle positioned in a loading zone going out of the loading zone from reception of a loading completion notification, a travel start time difference after which the second unmanned vehicle goes out of the loading zone before the first unmanned vehicle arrives at a deceleration start position is calculated, a travel start time of the first unmanned vehicle is calculated on the basis of a reception time of the loading completion notification and the travel start time difference, and a travel permission regarding the queuing zone for the first unmanned vehicle is output after the travel start time has come. As a result, it is possible to shorten a time length required for replacement of unmanned vehicles at a loading position and enhance productivity.
