The Traffic Monitoring Section in the MPD Transportation Analysis Group is responsible for the collection, analysis and reporting of vehicular traffic information throughout Arizona. Vehicle volumes, classifications, speeds and weights are collected at over 5,000 locations on the highway network using both temporary and permanent traffic monitoring stations and then archived electronically to a cloud-based server. After a series of quality assurance and quality control checks and analyses are performed, the data is posted to the Transportation Data Management System interactive website. The Traffic Monitoring Section is also responsible for estimating various traffic factors for the annual Highway Performance Monitoring System submittal and for performing regular field maintenance of the traffic monitoring stations and vehicle detection systems.
Travel Demand Modeling
With state-of-the-practice computer simulation tools, the Modeling & Forecasting Section prepares traffic forecasts for local, regional and statewide planning and design studies. The Modeling & Forecasting Section provides direct modeling services to MPOs, and technical guidance, training and assistance to MPOs, cities, counties, other government agencies and their consultants. The Arizona Statewide Travel Demand Model (AZTDM) is a planning analysis tool that simulates the interaction between people and the transportation system. The Modeling & Forecasting Section uses a series of mathematical models to replicate travel behavior in response to candidate policy, plan, and project scenarios. AZTDM is used to prepare the travel forecasts used for road design and transportation plans. These forecasts are produced for planning horizons as far out as 2050 based on the population and employment growth projections established by the Arizona State Demographer's Office and MPOs.
Geographic Information Systems
This program is responsible for oversight of Geographic Information Systems related to statewide roadway information, the authoritative roadway centerline known as Arizona Transportation Information System (ATIS), and the Highway Photo log inventory. The GIS team supports Federal submittals of the All Roads Network of Linear Referenced Data (ARNOLD), Model Inventory of Roadway Elements (MIRE), and Highway Performance Monitoring System (HPMS). The GIS team utilizes tools that include Aerial Photogrammetry, GPS, cartography, Online Mapping, geocoding, ArcGIS, dynamic segmentation, and linear referencing systems. The team provides agency wide services related to data creation, custom mapping requests, plus in depth data analysis for data driven decision making.
Highway Performance Monitoring System (HPMS)
HPMS is America's national database of highway information. It is a federally-mandated program launched in 1978 for which ADOT and other state highway agencies are responsible for administering. Roadway extent, use, condition and performance data is collected by and for the states and submitted to the FHWA on an annual basis. From a national perspective, the FHWA's primary intent with this program is to provide Congress with a policy tool for major highway legislation and funding decisions. The scope and scale of HPMS covers all publicly-owned roads and streets. In addition to state-owned routes, this includes those under the jurisdiction of all county, municipal and federal government agencies. It is the responsibility of the HPMS Coordinator in the MPD Data Management Section to ensure an extensive set of public highway attributes are collected and reported to FHWA through this program in accordance with specified guidelines and schedules.

Aviation Planning is responsible for developing and providing information to assist Airports with planning projects such as:
- Airport Master Plans
- Airport Layout Plans
- Environmental Assessments
- Drainage Plans
- Rates and Fees Studies
- Stormwater Pollution Prevention Program/Plans (SWPPP)
- Spill Prevention Control and Countermeasures plan (SPCC) information
In conjunction with Arizona’s public airports and the Federal Aviation Administration (FAA), ADOT develops the Five-Year Airport Capital Improvement Program (ACIP) to parallel the FAA’s Airport Capital Improvement Program. The ACIP has the dual objective of maximizing the use of State dollars for airport development and maximizing FAA funding for Arizona airports. Federal monies are derived mainly from taxes on airline tickets and are distributed by the Federal Aviation Administration directly to local airports through the national Airport Improvement Program.
State funding comes mainly from flight property tax, aircraft lieu tax, aircraft registration, and aviation fuel tax. The ACIP development process allocates money from the State Aviation Fund and distributes these funds across five major programs of airport development assistance. The State Transportation Board approves this distribution annually. The five programs are:
1) Federal/State/Local Grants
When a federal agency provides eligible grants directly to the airports, the State provides ½ of the local share of approved grants directly to the airports. Projects utilizing federal, state and local funds include: Airport design, construction, safety, security, capacity enhancement, equipment, maintenance, environmental, planning, and land acquisition.
2) State/Local Grants
The State provides either 90% or 95% funding for prioritized approved grants directly to the airports. Projects utilizing state and local funds only include: design, construction, safety, security, capacity enhancement, environmental, planning and land acquisition.
3) Airport Pavement Management System (APMS)
Prioritized projects maintaining and protecting eligible aviation pavement surfaces are performed by the State. The State provides 100% of the design and construction administration for APMS projects and 90% of the construction costs. The airports provide a local share of 10% of the construction costs and airport access through a joint project agreement.
4) Airport Loan Program
The State considers and awards loans to airports. These loans have typically included revenue generating projects like construction of new fuel farms, aircraft “T-hangars” and large aviation business hangars.
5) Statewide System Planning and Services
The State performs state-wide system studies and projects either with only state funds or with state and federal funds.

Transportation Performance Management
Transportation Performance Management (TPM) is a strategic approach that uses system information to make investment and policy decisions to achieve performance goals. ADOT has adopted TPM principles to ensure the right bundle of projects is selected and delivered to produce the performance outcomes desired by the agency, external partners, elected officials, and the public. TPM helps determine what results are to be pursued, using information from past performance levels and forecasted conditions to guide investments, measuring progress toward strategic goals, and making adjustments to improve performance. TPM is grounded in sound data management, usability, and analysis as well as in effective communication and collaboration with internal and external stakeholders.
The Performance Management Section is also responsible for the development of a risk-based asset management plan. Asset management is a strategic, systematic process to maintain and improve transportation assets using lifecycle and risk management analysis to sustain a good state of repair on our highways at the minimum practicable cost. The focus of the initial asset management plan is pavement and bridge. Per MAP-21, the minimum components of an Asset Management Plan are:
- A listing of pavement and bridge assets on the NHS and a description of the condition of each asset;
- Asset management objectives and measures;
- Performance gap identification;
- Lifecycle and risk analysis;
- A financial plan; and
- Investment strategies.
The ADOT Research Center is a catalyst for innovation at the Arizona Department of Transportation. The Research Center engages in two major functions:
- Administering the department’s research program
- Managing the product approval program
The Research Center conducts research studies that aim to improve processes and products within the agency. The studies address a range of issues covering five topic areas:
- Planning, Policy, and Communication
- Intelligent Transportation Systems (ITS), Traffic Engineering, Traffic Safety, and Transportation System Management and Operations (TSM&O)
- Materials, Construction, and Maintenance
- Bridges, Structures, and Roadways.
The Research Center encourages ADOT staff and the department’s stakeholders to submit ideas for research studies that will lead to improvements such as technical innovations, process and product improvements, and efficiencies. The goal of all research projects is the development of results that can lead to implementable solutions.
The product evaluation program reviews construction and traffic control products for the department, and lists those products approved for use on the Approved Products List (APL).
