Drivers dont respect new signs

I live in the new built by the crossing, it's been a week or two since the new signs are live and most drivers ignore them or do a U-turn to then go the other way. In just one day I have seen 3 possible collisions in this crossing. Only a few cars respect the no turn signs and go ahead putting in dangers drivers, cyclists and pedestrians, this makes other drivers speed up to avoid delays on their journeys. Honking in unbearable on a daily basis, no camera have been installed and I don't believe the speed camera is working, last week someone died in crash on this road and we still have no cameras to enforce this new signs and avoid more possible injuries. Could you please provide information on how are you going to tackle this issues, are cameras going to be installed on this crossing? Thanks.
