Senior Project Manager:
Roger Herzog

As the designated Metropolitan Planning Organization (MPO) for the Maricopa region, MAG plans and finances the regional transportation system. These responsibilities include the preparation of:

Regional Transportation Plan (RTP)
The RTP provides the overall plan or framework for all modes of transportation over the next two decades.

Transportation Improvement Program (TIP)
This is a schedule of specific transportation infrastructure projects to be constructed or implemented across the region over the next three to five years.

Arterial Life Cycle Program (ALCP)
The Arterial Life Cycle Program (ALCP) provides management and oversight for the street projects contained in the Regional Transportation Plan (RTP). The ALCP is a key safeguard that was part of Proposition 400 and represents more than $1.8 billion of investment over the next 20 years.

Traffic Data, Forecasts and Modeling
Transportation data such as volumes or road counts and modeling results used to support regional transportation planning activities are available here. Traffic count maps can be found here.

Regional Transportation Plan Freeway Completed Project Cards - Phase I
MAG, in conjunction with the Arizona Department of Transportation, has developed a new user-friendly way for members of the public to track projects that are being implemented as part of the Regional Transportation Plan funded by Proposition 400. A web-based, one-page card has been developed for each freeway project. The first set of project cards are available on the MAG website at

Intelligent Transportation Systems Program
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. The program helps coordinate regional activities, meet federal requirements and recommend ITS infrastructure investments in the region.

Transportation Safety Planning Program
This program, launched in 2000, is focused on identifying current and emerging road  safety issues and needs, and helping to implement solutions through initiatives at state, regional and local levels.

Transportation Studies and Reports
This page provides a categorized list of current and recently completed transportation studies and final reports.

Commuter Rail Planning
The purpose of Commuter Rail Planning is to study and evaluate commuter rail options (existing freight corridors and possible rail extensions) for the MAG region and the potential connecting routes immediately adjacent to the MAG region. Commuter Rail Planning encompasses a variety of elements, specifically MAG Commuter Rail System Study, Grand Avenue Commuter Rail Corridor Development Plan, UP Yuma West Commuter Rail Corridor Development Plan, Commuter Rail Stakeholders and the Commuter Rail Strategic Plan.

Federal Stimulus Legislation
MAG member agencies have submitted projects to MAG staff that they have identified to be ready in a timely manner upon receipt of federal funding. MAG staff has compiled the projects and funding amounts and will offer them to members of the Arizona congressional delegation to inform them of regional opportunities as it relates to transportation and infrastructure development.

MAG Transportation Data Management System
This traffic counts data retrieval system serves as a primary data management tool for region wide traffic counts information; it provides for storage, efficient management, update, analysis and retrieval of all traffic counts data available at MAG; it also provides user-friendly Web-based access to the traffic counts data for the MAG member agencies, consulting and business community, and general public.

MAG Performance Measurement Data
This performance measurement web based tool provides access to all performance measures developed by MAG in 2008 and 2009. Measures are based on multi-modal observed data on a system and corridor scale. This tool will serve as the current and future repository of MAG’s Performance Measurement Program. New measures and performance analysis will be posted in the sites as new data becomes available. This tool is linked internally to the MAG Transportation Data Management System.

New transportation data and data management tools will be posted on the site as a part of the ongoing site development effort.

Access Management
Access management is the systematic control of the location, spacing, design, and operation of driveways, median openings, interchanges, and street connections to a roadway. The purpose of access management is to provide vehicular access to land development in a cost-effective manner that preserves the safety and efficiency of the transportation system.  Access management can increase vehicular and pedestrian safety, reduce traffic congestion through improved traffic flow, improve air quality, preserve long-term property values, increase economic viability, and preserve the environment.
