Hunt Highway is a major thoroughfare servicing thousands of commuters every day, many traveling through several signals along the Hunt Highway corridor to arrive at their destination. When two new signals were introduced in 2020, adding to the original 12 signals along the highway, anticipated growth prompted the need to improve signal timing within the corridor. The Maricopa County Association of Governments (MAG) selected Burgess and Niple (B&N) to improve signal optimization along Hunt Highway. 

B&N began the study by conducting a field visit to review the existing signal infrastructure in the corridor. The B&N team used data from this field visit to inform signal infrastructure recommendations and create improved time of day plans. Included in the study was a crash analysis to inform operational recommendations such as creating positive offsets at signalized intersections and reconfiguring shared-through and left turn operations on minor approaches to a left only and through-right operations. The corridor now consists of 14 coordinated intersections with improved time of day plans.
