Manage traffic flows
The device manages vehicle priorities in a two-way ramp, not allowing vehicles to cross.
Basic solutions:
Scenario 1 : A vehicle is heading towards the exit at traffic light no. 2. The vehicle is detected. Traffic light no. 1 then turns red. Traffic light no. 2 remains red for an adjustable period of time (TRB), then changes to green for the green exit light time (VPD) which can also be set. After VPD, traffic light no. 2 goes back to red. Traffic light no. 1 stays red during TRB, then defaults back to green.
Scenario 2 : Several vehicles appear in the direction of the exit. Same as scenario 1. Each time a new vehicle is detected in the direction of the exit, the VPD time is not increased.
