The present invention provides a technology which assists an automatic travel device in crossing a crosswalk more safely. This crossing assistance system 1 assists, at a crosswalk where a pedestrian traffic light 20 is installed, an automatic travel device 10 in crossing the crosswalk. The automatic travel device 10 transmits a crossing determination request signal to a pedestrian traffic light 20 at a time point at which the automatic travel device arrives at the crosswalk to which the crossing assistance system 1 is applied. When receiving the crossing determination request signal from the automatic travel device 10, a processing unit 22 of the pedestrian traffic light 20 determines whether crossing is possible on the basis of a display state (red signal or blue signal) of the pedestrian traffic light 20 or the remaining time of the blue signal, transmits a crossing instruction to the automatic travel device 10 when the crossing is possible, and transmits a stop instruction to the automatic travel device 10 when the crossing is not possible. The automatic travel device 10 executes the crossing at a safe timing on the basis of the crossing instruction or the stop instruction from the pedestrian traffic light 20.
