**VAL : VAL is a type of automatic rubber-tyred people mover technology, based on an invention by Professor Robert Gabillard (Université Lille Nord de France). It was designed in the early 1980s for the then new metro system in Lille. The acronym was originally for Villeneuve d'Ascq à Lille (Villeneuve d'Ascq to Lille), the route of the first line to be projected (and inaugurated). It now officially stands for Véhicule Automatique Léger (automatic light vehicle). In contrast to some other driverless metro systems like the Docklands Light Railway or Vancouver's SkyTrain, the VAL design uses platforms that are separated from the track by a glass partition, to prevent waiting passengers from straying or falling onto the track.
