Thanks for reporting this issue to Gilbert 311! We will look into it. The over night plan runs until 6am and it is a shorter snappier cycle length to try and be more responsive to the lower volumes. It may be time for a change however. Thanks again for reaching out...Mike

Thank you Mike, I wouldn’t mind so much if both directions were the same duration, but north and southbound have a much longer green light during the early morning hours.

Jeff,
NS is the coordinated phase so they will likely never be the same all extra time goes back to coordinated phase. EW is set to min recall so it will always serve at least the min time (10 sec green) if there are cars present it serves them and adds time as vehicles pass through the detection area up to the maximum split for the movement or time programmed, all unused time goes to NS. If there are vehicles approaching the intersection EW but not yet in the detection area and the minimum time has been served (10 sec) it will Gap out (end) and the vehicles waiting will need to wait until the next window in the cycle opens. EW has more time available in the AM plan (48+) than NS (32+) but due to NS being coordinated the unused time from EW goes to NS. I know this can be confusing but it sound like you have a lot of gaps in traffic that are allowing the signal to switch to NS. I did make a change today to the amount of time it extends when a vehicle passes though the detection area that will help. I will try and watch again soon. I did not see any back ups last time but it was a bit later in the morning and the time was extending as programmed if people were in the detection area closer to the signal, it may be more of a problem earlier but the change I made today should help. ....Mike

I noticed a longer green for EW today, I also noticed that the traffic signals are a lot more coordinated on Saturday when I make my commute down QC road into Chandler. I don't usually travel south on Val Vista at QC but noticed some time ago that the SB left turn arrow no longer has a flashing yellow. Not sure if that was intentional. Thank-you again for addressing my concerns. -Jeff
