1. A rail-guided vehicle that travels along a rail, comprising:
a vehicle body;
a detection device provided in the vehicle body that detects a position of rail peripheral equipment, wherein the detection device comprises a light projecting/receiving sensor and a contact-type sensor, each configured to detect a position of the same rail peripheral equipment;
a measurement device that measures behavior of the vehicle body at a time of detection of the rail peripheral equipment by the detection device; and
an evaluator that evaluates a detection result of the detection device on a basis of a measurement result of the measurement device, and wherein the evaluator confirms an abnormality of the rail peripheral equipment only when both the light projecting/receiving sensor and the contact-type sensor indicate an abnormality.
