The traffic signals at Hillcrest and Lebanon in the NB and SB directions are not operating correctly. When I go to the gym at 5:30am the light is cycling every 15 secs or so, I assume to low traffic. But on my way back at 6:30am the light in the NB/SB direction stays Red for over 2minutes while there's little to no traffic tripping the light in the EB/WB direction. Also on my way from work at 5:30pm going NB the signal only stays green for a short period of time not allowing all the cars waiting to get through the intersection. Can someone check the timing/sensors in this intersection?
Thanks for the help!

Thank you for your message. We will check the timing and see if changes are needed or if something is malfunctioning.

The light at Lebanon and Ohio has the same problem around 6:30am.

We will watch the location, however, the logs indicate this location as well as Hillcrest are working as programmed. At 6:15am the coordinated signal timing along Lebanon goes into effect. The coordination gives preference to Lebanon beginning at that time. The cycle length that is used along Lebanon and several of our coordinated corridors in town during the AM peak is 120 seconds. Ohio has programming that will allow for it to get nearly 50 seconds of that 120 second cycle. However, if volumes on Ohio are low the unused portion of time is given back to Lebanon.
At Hillcrest and Lebanon, Hillcrest could get nearly half of the cycle. When volumes are light, the unused time from Hillcrest is given to Lebanon.
We did try shorter cycle lengths in this area on Lebanon two years ago that could still provide progression in both directions on Lebanon, but it required removing the time for the protected left-turn arrows. We received many complaints about the arrows not turning on and changed the timing back to the 120 second cycle.
