In that mean time traffic will be piling up on the other three sides now when they open the next side again they will keep it open for as long as it takes for the traffic on that side to clear. Sometimes you might even be made to wait for 5 full minutes.
The manual operation of the signal will be given to any guy who is the friend of the traffic police. And road users will be at the mercy of that individual. He will open one side and will start talking to his friends for a long time during which you will keep watching him when he will show mercy and open your side of the traffic.
