PPROBLEM TO BE SOLVED: To provide a reverse travel prevention system, capable of further early detecting reverse travel of one' own vehicle to prevent the reverse travel of the own vehicle. PSOLUTION: The reverse travel prevention system 100 for preventing the own vehicle which enters from a merging passage to a main line from reversely traveling along the main line by determining whether the own vehicle is reversely traveling or not based on output of an imaging device 2 mounted on the own vehicle includes: a stationary object extraction means 10 for extracting a stationary object E around the merging passage in each of image data successively taken by the imaging device 2; a displacement pattern acquisition means 11 which acquires a displacement pattern of the stationary object E changed in position on the image data according to the movement of the own vehicle; a reverse travel determination means 12 which determines whether the own vehicle is reversely traveling or not based on the displacement pattern of the stationary object E; and a reverse travel prevention support means 13 which supports prevention of the reverse travel when the reverse travel is determined.
