Traffic Light Sequence

Over the last few weeks, the traffic light sequence has caused several delays and near misses due to the lights being out of sync. Previously, the traffic lights would register a vehicle emerging from the coach station and provide priority. However the lights constantly randomly turn red on Fen Street for nothing exiting the coach station. Plus the lights remain on the red aspect a long time. I have been a resident of Brooklands for a number of years and this has only recently become a problem. Please can this be returned to the original settings.
