Abstract
The invention provides LED tunnel lighting control system and method. Entry vehicle sensing units are distributed at the entry position of an entry of a tunnel. Exit vehicle sensing units are distributed at the exit position of an exit of the tunnel. Inside-tunnel vehicle sensing units are distributed inside the tunnel. When the entry vehicle sensing units sense a vehicle running into the entry and send entry counting increase signals to an entry counter, the entry counter increases. After each time of increase of the entry counter, the entry counter transmits the increased entry counter value to a processing unit. When the exit vehicle sensing units sense a vehicle running out of the exit and send exit counting increase signals to an exit counter, the exit counter increases. After each time of increase of the exit counter, the exit counter transmits the increased exit counter value to the processing unit. The processing unit starts a timer when the entry counter value equals the exit counter value.
