Update timing sequences for at least 1/3 of traffic signal corridor's annually to ensure all corridors have the most efficient timing necessary to move traffic effectively with minimal delays.  Outdated timing sequences of signals can cause longer travel times, unnecessary stops and delays, higher levels of fuel consumption, and an overall negative impact on air quality due to automobile emissions.

Signal engineering staff utilize excel worksheet to keep track of the timing schedule for each corridor.  Staff records timing adjustments conducted on each corridor per timing schedule plan.  Excel sheet is reviewed to determine the count of corridors per quarter have been retimed to improve traffic flow.
