The present invention provides a transport management method and apparatus for controlling the transport of a plurality of unmanned vehicles traveling over a travel grid formed from a plurality of nodes provided at stationary positions, and connection routes connecting the intervals between these nodes. The transport management apparatus according to the present invention has a first function for searching for a travel route for each unmanned vehicle in which an unmanned vehicle does not travel in the opposite direction over the same connection route as another unmanned vehicle and a second function for solving the progression impossibility of an unmanned vehicle using a node passing sequence change process, detour route search process or passing route search process, in the case when a progression impossibility of any unmanned vehicle is detected following simulation of the timed movements of each unmanned vehicle based on travel routes obtained by means of the aforementioned first function. As a result, the carrier efficiency therein is improved.
