Performance Context
To evaluate network performance and propose enhancements reflecting the Federal Highway Administration performance-based approach described in U.S.C. §450.206 of Title 23, jurisdictions require an evaluation platform addressing both infrastructure and traffic.

Regional Partnerships• Managing travelers cross jurisdictional boundaries requires
regional coordination• Regional transportation mobility partners to include City of
Tucson and other governments• Coordinating agencies include law enforcement,
emergency management, health, economic and community development
• Operational expertise in smart transportation infrastructure, modeling and demand management at the University of Arizona College of Engineering could be leveraged to create a regional transportation operations and research center.
