Traveling vehicle system

A traveling vehicle system comprising:

• a track network including a first track, and a second track and a third track that diverge from the first track at a diverging section;
• a plurality of traveling vehicles that travel in the track network;
• and
• a controller programmed and configured to control travel of the traveling vehicles and to include:
• an abnormality detecting unit configured to detect an abnormality in a track on the downstream side of the diverging section, including at least the second track;
• and
• an entry determining unit configured to, in a case that one of the traveling vehicles that has just passed through the diverging section enters the second track and another one of the traveling vehicles that has immediately thereafter passed through the diverging section is about to consecutively enter the second track, when the abnormality detecting unit has detected no abnormality, skip determination of whether the other one of the traveling vehicles that has immediately thereafter passed through the diverging section is allowed to enter the second track and, when the abnormality detecting unit has detected the abnormality, determine whether the other one of the traveling vehicles is allowed to enter the second track.
