Each piece has Infra-red encoding patterns embedded in the track, with an IR transparent ink top coat for traction and protection. The codes serve as markers of lane position (there are 16 possible lanes), and track piece type and orientation. The Supercars translate this information to determine where they are in relation to the overall track, how fast they’re moving, and which direction they’re headed.


Unique markings on each track piece allow software to identify the type of piece and enable the Supercars to determine their locations.
