Responded to the requester and explained that staff are reviewing the Walnut Street and South Drive signal operation, including detection and timing, to determine whether maintenance or an adjustment is needed.

Thank you for reporting the signal timing concern at Walnut Street and South Drive. We understand the frustration of waiting on Walnut when there does not appear to be traffic entering from South Drive. We are reviewing the signal operation to determine why South Drive is receiving service and whether the detection and timing are working as intended. Because Walnut is a coordinated corridor, some red time may be necessary to maintain progression and serve pedestrians or vehicles that are not immediately visible. However, the signal should not repeatedly interrupt Walnut traffic because of an unintended or continuous call. We have logged the concern and will determine whether an adjustment or maintenance work is needed. Thank you for bringing it to our attention.
