Claim Text:
1. A computer-implemented method for determining a sequence order for vehicles in one or more image frames from an operational video, the operational video acquired from a fixed video comprising a field of view associated with a vehicle merge area where upstream traffic from a first lane and upstream traffic from a second lane merge to a single lane, the method comprising: obtaining operational video from a fixed video camera; detecting, within a region of interest (ROI) of the one or more image frames from the operational video, a first area and a second area in the vehicle merge area using a trained classifier that is trained to detect the first area and the second area, wherein traffic from the first lane and no traffic from the second lane traverse the first area and wherein traffic from the second lane and no traffic from the first lane traverse the second area; and determining the sequence order of the vehicles based on the first area and the second area that are detected.
