Claim 0:
1. A method performed by a road identifying system of a vehicle for localization of the vehicle in a multi-level road system, the method comprising:
determining with support from a positioning system, a position of the vehicle;
identifying based on the vehicle position with support from at least a first digital map, a multi-level road system in which the vehicle is positioned;
identifying with support from the at least first digital map, a number of road levels of the multi-level road system;
obtaining image data with support from one or more image capturing devices adapted to capture surroundings of the vehicle;
determining a road level at which the vehicle is positioned based on the number of road levels and based on feeding the image data through a neural network trained to classify road level based on context of image content;
identifying based on the determined road level with support from the at least first digital map, at least one of a road and a lane of the multi-level road system at which the vehicle is positioned; and
localizing the vehicle in the multi-level road system based on the road and lane of the multi-level road system at which the vehicle is positioned.
