PROBLEM TO BE SOLVED: To ensure fail-safe control even if a fault occurs in a signal transmission means between automated vehicles in a merging area. SOLUTION: While a signal generator 30 outputs a base signal (current signal) to conductors 25X and 25Y as the signal transmission means between the automated vehicles Ba and Bb in a merging area P, and each automated vehicle Ba, Bb reads in bar code information on a plate 21a, 21b with an information reader 15a, 15b to detect an entrance into the merging area P, if a base signal receiving coil 15a, 15b does not detect the base signal, control is performed to make a stop in the position of a temporary stop plate 22a, 22b. Signals exchanged between the automated vehicles Ba and Bb and the base signal have different frequencies or signal patterns. COPYRIGHT: (C)2004,JPO
