A movable object includes a sensing device for detecting traveling-route reflector on a travel surface so that a region outside a floor projection region of the movable object, in particular the traveling-route reflector forward, can be detected. Detecting the traveling-route reflector across a wide range of areas allows traveling control, such as gradual deceleration before entering a curve, speed regulation based on a turning radius at the curve so that centrifugal force on a rider or load is not too great. Also the movable object can detect a branch point or an intersection beforehand, decelerate, and notify the user for user's instruction regarding the traveling direction. Furthermore, for a movable object autonomously traveling with an item mounted thereon, a single sensing device detects the traveling-route reflector and also serves as a safety sensor for avoiding collision with any other objects therearound.
