Apart from reading vehicle numbers passed at a given point the Automatic Vehicle Identification (AVI) system employed by Spoornet is required to build a record of the train consist and requires identification of the vehicle types such as wagons and locomotives. This must be accurate even if electronic tags are missing or damaged on some of the vehicles, or when the train speed or direction changes while being measured. In many instances clearance between tracks on a double line section prohibit the installation of reader antennas between the lines. Under these conditions it is required that the train consist shall not be corrupted while two trains pass on a double line at the same site. In order to ensure reliable performance in accordance with these requirements different pattern recognition algorithms had to be implemente
