Report
Summary
The City of Phoenix Street Transportation Department (Streets) wishes to coordinate all City of Tolleson-owned traffic signals by connecting their signals to Phoenix's ATMS, which will improve the safety, efficiency, and convenience of vehicular travel through and around both jurisdictions. The City of Tolleson is located west of Phoenix city limits, between Buckeye Road and McDowell Road, and is surrounded by Phoenix on three sides.
Streets owns and operates a central traffic management system to monitor and control traffic signals in real time. This partnership with the City of Tolleson will allow for base coordination plans and real-time Active Traffic Management (ATM) in response to incidents and special events affecting traffic flows on the west side of Phoenix. Streets will provide traffic signal coordination timing plans to the City of Tolleson, so they can program Tolleson's traffic signals on Phoenix's network. By having Tolleson's traffic signals on Streets' ATMS, Tolleson's traffic signal clocks will be synchronized with Phoenix's, allowing for progression of traffic and responding with predetermined timing plans to resolve reoccurring and non-reoccurring congestion. Synchronizing the traffic signal timing of both jurisdictions will provide the traveling public the ability to traverse along the corridors of McDowell Road, 83rd Avenue, 91st Avenue, and 99th Avenue with improved traffic flow. Additionally, the installation of communication nodes in the City of Tolleson city limits will further strengthen the City of Phoenix traffic signal communications network and provide a more efficient connection to remote signals owned and operated by Streets.
Contract Term
The term of the IGA will be five years beginning on or about Feb. 17, 2021. Provisions of this agreement include an option to renew for an additional five years with the consent of both parties, which may be exercised by the City Manager or his designee.
Financial Impact
The total estimated cost of the communications infrastructure is $45,000. The estimated contribution from the City of Tolleson will be $37,500. The estimated contribution from the City of Phoenix will not exceed $7,500. Funding is available in the Street Transportation Department's Capital Improvement Program budget.
Location
Various locations in the City of Tolleson, which borders the City of Phoenix at McDowell Road between 99th and 83rd avenues, 75th Avenue between Buckeye Road and Van Buren Street, and Buckeye Road between 107th and 75th avenues.
