vehicle actuated

[dandibibka]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:
We present here a vehicle-actuated traffic signal control scheme for a simple geometry of a diamond interchange. The scheme is guaranteed not to have blockage, to adjust automatically to changing flows and operate on a shorter mean cycle time than most fixed-time plans, at least during times of heavy traffic.

Заранее спасибо
