Regional Safety and Operations
- Transportation Safety and Security Program
- Regional Pavement Management System
- Intelligent Transportation Systems - Technology and Operations
PAG supports regional transportation operations by leading local jurisdictions in planning for and implementing coordinated operations programs and projects. For the PAG region, this means developing and realizing opportunities for improved traffic signal coordination, traveler information consolidation and delivery, work zone coordination, traffic incident management and pavement rehabilitation throughout the region.
PAG coordinates a Regional Pavement Management System and has recently developed "action plans" for specific transportation operations areas as part of a Regional Concept for Transportation Operations. Local agencies have embraced the concept of regional transportation operations and have gained from programs that enable more frequent traffic signal timing review and adjustment, improvements to construction and traffic incident data for the public, training and exercises to coordinate multi-agency traffic incident response, and pavement inventory collection and rehabilitation.

Transportation Safety and Security Program
The Transportation Safety and Security Program was launched through PAG’s inaugural Regional Transportation Safety Forum held in May 2003. The forum served as a venue for the exchange of transportation safety information with updates on federal transportation legislation and safety activities, lessons learned from other regional programs, and a wide array of information from regional stakeholders on the various transportation safety activities going on throughout the region. The forum also identified some of the key issues and needs related to transportation safety in the region.
Transportation safety was identified as the No. 1 concern by the public as part of the 2030 Regional Transportation Plan outreach efforts in the Tucson metropolitan area. This clear indication demands better planning and coordination of transportation safety activities for the region.
PAG's transportation safety planning work extends statewide through membership on the Governor's Traffic Safety Advisory Council and development of a statewide plan for transportation safety and related programs. This work has enabled PAG to have more impact and input into the development of statewide funding strategies, legislation development and program activities to address issues like safety education, enforcement, data needs, and safety analysis among others.
PAG is also actively involved in regional transportation security activities. This includes PAG's partnership with the Pima County Office of Emergency Management and Homeland Security in holding Regional Incident and Emergency Management Forums in 2003 and 2006, a tabletop exercise for interstate traffic incident management in 2007, coordination of planning activities for hazard mitigation and emergency transportation, and participation in the development of a new evacuation plan for the PAG region.

Regional Pavement Management System
Pima Association of Governments, which owns no roadway infrastructure, coordinates a Regional Pavement Management System to ensure compatibility of pavement management databases and information collection techniques among PAG's member agencies.
The system provides member agencies with the appropriate tools and data to assess the deterioration of publicly owned roadways and other roadway infrastructure. Accurate management of our region's infrastructure assets is essential for allocating and optimizing available maintenance funding.
PAG coordinates regional pavement data collection through the use of a shared resource, the Automatic Road Analyzer (ARAN) pavement management van. The ARAN van is operated by the City of Tucson and collects consistent and accurate roadway data, such as pavement condition, roadway ride quality and precise location information of specific features on or near the roadway. The ARAN van uses a variety of sensors, a sub-meter global positioning system, video and machine vision systems, and computers. More information about the ARAN van housed and maintained by the City of Tucson is available at Transview.org.

Intelligent Transportation Systems - Technology and Operations
Intelligent Transportation Systems, or ITS, is the application of technology-based solutions such as advanced sensors, computers, electronics and communication technologies, to improve the overall safety and efficiency of the regional multimodal transportation system. ITS is rooted deeply in transportation operations using technology application to ensure safe and efficient operation of the transportation network.
PAG's ITS program helps coordinate regional activities, meet federal requirements and recommend ITS infrastructure investments in the region. To assure continuing focus and advancement of the ITS program, PAG has created the Transportation Systems Subcommittee (previously known as the Tucson Area ITS Working Group). This committee consists of representatives from the Federal Highway Administration, Arizona Department of Transportation, Arizona Department of Public Safety, Sun Tran, University of Arizona, and the eight PAG member agencies. The committee served to guide the development of the ITS Strategic Plan and a regional ITS architecture in 2004 to serve as the roadmap for ITS infrastructure investments and coordination of technology-based solutions in the regional multimodal transportation system. The regional ITS plan and ITS architecture build upon the work that has been done in conformance with the original ITS plan developed for the region in 1996.
PAG is taking a more proactive role in regional transportation operations through coordinated efforts with its member agencies to develop a Regional Concept for Transportation Operations, or RCTO. Essentially, an RCTO is a plan for coordinated transportation operations – that is, mapping out specific strategies of how transportation agencies, public safety, emergency services, transit and others can work better together, to get the most benefit out of the region’s existing systems and transportation resources.
For the PAG region, the development of an RCTO means developing and realizing opportunities for better traffic signal coordination, traveler information and work zone coordination throughout the region.
Local jurisdictions will gain opportunities for group purchase of equipment and services for transportation operations, improved personnel resources and expertise, and improved information and data exchange to help improve transportation operations regionwide. PAG coordinates the regional operators to provide a neutral table for cooperation and to link operations and planning, resulting in more opportunities for funding.
