Abstract: Disclosed herein are system, method, and computer program product embodiments for monitoring a detection zone of a road to detect a vehicle moving in a wrong direction. A method can comprise identifying a first object in a first image; identifying a second object in a second image; and determining if the first object and the second object is a same vehicle. The method can further include determining a movement direction of the vehicle and a moving distance that the vehicle has traveled in the movement direction, and determining if the movement direction of the vehicle is the same as the monitored direction. In response to a determination that the movement direction is the same direction as the monitored direction and the moving distance of the vehicle is larger than a predetermined monitoring distance, the method can generate a warning signal to indicate that the vehicle is traveling in a wrong-way.
