Phoenix Freeway Management System
Kimley-Horn has partnered with ADOT in the design, construction support, software, system integration, and testing for one of the nation’s most sophisticated Advanced Traffic Management and Traveler Information Systems, the Phoenix Freeway Management System (FMS), for more than 20 years.
Core systems for the initial phases included detection, dynamic message signs, telecommunications, ramp metering, and CCTV for nearly 60 miles of urban freeway primarily on I-10 and I-17. The first four phases went live in 1995, which also included an 18,000-SF Traffic Operations Center.
Kimley-Horn completed an extension of this FMS on Loop 101, which was designed and constructed on a fast-track to be able to implement FMS functions prior to the 2008 Super Bowl in Glendale, AZ. This FMS has provided a critical regional fiber backbone to support connectivity among state and local agencies in the Phoenix metro area.
The system is centrally controlled from an 18,000-square-foot Traffic Operations Center (TOC). The TOC is equipped with a 32-monitor matrix of 37-inch color monitors that display images from the closed-circuit television cameras along freeway corridors. Individual operator workstations use an integrated graphical user interface to facilitate incident management and emergency notification. Traveler information is disseminated via fiber-optic changeable message signs on freeway corridors, a website, and radio broadcasts using RBDS (Radio Broadcast Data System) technology.
