Master control logic
Signal lamp conversion principle: the signal lamp conversion is controlled in chronological order, can be by the time that changes signal transformation is set.Guaranteeing on the basis of sequential control, when current direction do not had car then signal lamp become immediately to turn left to pass through.When the left-hand rotation direction did not have car, it is current that signal lamp becomes other direction.
Traffic post with four crossings is that example describes below:
At first to lay video camera, and vehicle alarm zone is set at four crossings.System can receive the warning information that a vehicle sails into when vehicle sails the alarm zone into.System thinks that vehicle walked sky when green light lets pass that current direction did not have vehicle and sailed alarm into 30 seconds.
During the program initial launch, acquiescence north and south is current earlier.No through traffic for east-west direction.
When vehicle had been walked sky when north and south is current, the left-hand rotation direction had the car wait then to change left rotaring signal in advance over to.
When vehicle had been walked sky when north and south is current, the left-hand rotation direction did not have car to wait for, east-west direction has car to wait for that signal lamp directly becomes thing can manage it, and wait in north and south.
When north and south was current, left turning vehicle had been walked sky, and east-west direction has car etc. to bide one's time.It is current that signal lamp becomes thing, and wait in north and south.
When north and south is current, arrived maximum latency, car is not also covered, and east-west direction or left-hand rotation direction have the same signals that change of biding one's time such as car.
When north and south is current, turns left and between east and westly all do not have a car wait.Then North and South direction keeps current state constant always.
Logic when east-west direction is current, can be with reference to North and South direction.
