Véhicule Automatique Léger
Véhicule Automatique Léger (lit. 'automatic light vehicle') or VAL is a type of driverless (automated),
A total of 11 lines in 8 systems based on the VAL technology are currently in operation worldwide. The current version of the VAL product is marketed as NeoVal (with a distinction between AirVal for airport environments and CityVal for more conventional transit environments).

Technology
Original VAL
The VAL system uses a fully automated elevated
The vehicles are lightweight 2-car sets (VAL 206 or VAL 208) with 124 total capacity, or twin sets (VAL 256) with 80 seated and 160 standing capacity. All axles on these vehicles are motored with 150 kW (201 hp) electrical motors. The system detects the location of trains on the guideway by the use of ultrasonic sensors.[3] VAL uses fixed-block signalling.
VAL can cope with unanticipated demand by inserting additional trains into the network as required by remote command from the control center. The control center computer system automatically speeds up or slows down trains in order to maintain a timetable. The VAL system can handle headways as small as 60 seconds, and the Lille VAL system rapidly proved itself with a 99.8% availability.[4]
In contrast to another early driverless metro system, the
In addition to the trains being driverless, the station platforms are unstaffed in normal operation. In the original
NeoVal
In 2006 the NeoVal project, successor of the VAL, was announced. It features
The NeoVal is offered in two versions:
- the CityVal version designed for conventional transit environments (car width 2.65 m (8 ft 8 in)) with the first implementation on Line B of the Rennes Metro;
- the AirVal version designed for airport environments (car width 2.80 m (9 ft 2 in)) with the first implementation on the Suvarnabhumi Airport Automated People Mover at Suvarnabhumi Airport, Thailand.

Defunct systems
- Airport Transit System at Chicago's O'Hare International Airport (opened in 1993 and replaced by a Bombardier system in 2019 and reopened in 2021)
- Jacksonville, Florida, had a VAL line inaugurated in 1989; it was shut down in December 1996 and replaced by a monorail, the Jacksonville Skyway. The rolling stock was sold to O'Hare.
