Report
Summary
The purpose of this Agreement is to allow the State to provide funding to the City for the procurement and installation of Intelligent Transportation System (ITS) equipment for the traffic management of arterial corridors surrounding the Interstate 10 (I-10) Broadway Curve Improvement Project (Broadway Curve). The City will purchase and install the equipment within one year of the execution of this Agreement and will be reimbursed for costs incurred not to exceed $1,223,000.
The Broadway Curve project is planned to improve I-10 between the I-10/Interstate 17 (I-17) Split Traffic Interchange and the Congressman Ed Pastor Freeway (Loop 202-South Mountain Freeway). The project will represent the region’s first urban freeway reconstruction project with construction estimated to begin in early fall 2021.
In November 2019, the Maricopa Association of Governments (MAG) approved a study to identify strategies to mitigate construction impacts. After one year of data collection, analysis, infrastructure inventory, and coordination, a comprehensive mitigation strategy was identified. In 2020, MAG launched a study to inventory and analyze traffic signal systems at seven traffic interchanges and fifteen arterial corridors surrounding the Broadway Curve. Technical staff from the Arizona Department of Transportation (ADOT) and Phoenix collaborated with MAG throughout the study and provided detailed information about the traffic signal systems within the City. The overall goal of the study was to assess the traffic management capabilities of the corridors and identify achievable traffic signal system enhancements that could be implemented prior to the start of the Broadway Curve project. Several vital ITS elements were evaluated including detection, monitoring, preemption, intersection capacity, and traffic signal controllers.
Enhancing the City arterial traffic signals within the area of the Broadway Curve will help ease congestion during construction detours and closures.
