Véhicule Automatique Léger or VAL is a type of driverless (automated), rubber-tyred, medium-capacity rail transport system. The technology was developed at the Lille University of Science and Technology, was marketed by Matra, and first used in the early 1980s for the Lille Metro system, one of the world's first fully automated mass-transit rail networks, preceded only by the Port Island Line in Kobe, Japan. The VAL technology is now marketed by Siemens, which acquired Matra in the late 1990s.
