ADOT 2023 Average Annual Daily Traffic (AADT)

The Annual Average Daily Traffic (AADT) for sections of roads for all vehicle types, including single and combination trucks, reported in the 2023 Highway Performance Monitoring System (HPMS) federal report. Annual Average Daily Traffic (AADT) is used to represent [vehicle traffic] on a typical day of the year and is important for planning purposes, such as defining the federal functional classification of a roadway. The values are calculated using data collected from traffic counter devices, such as Automatic Traffic Recorders (ATR), Weigh In Motion (WIM) devices, and short term counters using tubes. All available traffic data collected throughout the year are then summed and divided by 365 to calculate the annual average daily traffic. Single unit trucks are any trucks that meets the requirements established for the FHWA Truck Classification Method for Categories 4 through 7. Combination unit trucks are any trucks that meets the requirements established for the FHWA Truck Classification Method for Categories 8 through 13. Refer to the Federal Highway Administration website for more information about truck classifications. Reported Extent: State Highway System (i.e. all ADOT-owned roads), National Highway System (NHS), and all federal aid-eligible roads. Federal aid-eligible roads include urban roads classified as minor collectors or above (functional system 1-6) and rural roads classified as major collectors or above (function system 1-5). Roads where ATRs are available, counts are updated annually. For roads where short term counters must be used, traffic counts are collected every three years for all National Highway System (NHS) roads as well as interstates (functional system 1), principal arterials (functional systems 2-3), and sample panel sections. All other federal aid-eligible roads, including minor arterials and collectors, are collected every six years. On one-way roadways and ramps, the AADT represents the single-direction of traffic. For two-way roadways, AADT is reported only on the cardinal direction of the roadway and represents the total traffic for both the cardinal and non-cardinal directions of travel. Note, the cardinal direction refers to the direction of increasing mileposts.
ADOT 2024 Junctions and Junction Legs

Junctions are locations of at-grade intersections, restricted crossovers on divided highways, and termini points for specific routes. The junction layer is used when identifying the number and type of intersection signals or stop signs as part of the Highway Performance Monitoring System (HPMS) federal report submittal (refer to the [HPMS field manual, items 31-33]). Junctions are also used in statewide safety scoring and have been adjusted for MIRE requirements. Junction legs are 150 foot linear segments, or legs, on either side of a junction. They are used to support traffic safety analysis. Reported Extent: Junctions exist on all paved public roads where an at-grade junction/intersection exists. Junction legs are generally created anywhere at-grade junctions exist. While they have been created on all ADOT-owned roads, they may not be as prevalent on locally-owned roads.
ADOT 2024 Average Annual Daily Traffic (AADT)

The Annual Average Daily Traffic (AADT) for sections of roads for all vehicle types, including single and combination trucks, reported in the 2024 Highway Performance Monitoring System (HPMS) federal report.

Note, the cardinal direction refers to the direction of increasing mileposts.
ADOT 2024 All Roads Network

The Arizona Transportation Information System (ATIS), also referred to as the All Roads Network, is a spatial file that represents the centerlines of all roads in Arizona. All roads open to public travel are included but the file may also include administrative (i.e. service) roads, private roads, and other roads restricted from the public. This layer is submitted in the annual Highway Performance Monitoring System (HPMS) federal report in the All Roads Network of Linear Data (ARNOLD) spatial dataset. All event layers describing road designations and attributes, such as functional system and speed limit, refer to ATIS to identify the route ID and measure locations for the features on the road network. Reported Extent: All roads in Arizona
ADOT 2024 Through Lanes

The number of through lanes on a roadway, which are lanes pass through at least two intersections and do not taper or turn into a turn lane. This event layer also includes the average lane width for the through lanes. To learn more about through lanes, refer to the [ADOT Glossary - Lanes] webpage. For undivided highways, where there is no physical barrier between opposing lanes of traffic, through lanes represent the total number of lanes on both sides of the road. For example, if there are 2 through lanes on the cardinal side of the road and 2 lanes on the non-cardinal side of the road, the number of through lanes reported is 4. Note, cardinality refers to the direction of increasing mileposts. For roadways that have no striping, such as in residential neighborhoods, the number of through lanes is reported as 2. For divided highways, through lanes are reported for the individual roadway. For example, if there are 2 through lanes on the cardinal highway, the value is reported as 2. Important: Many roadways have estimated values for the number of lanes and average lane widths. These values were based on the functional system of the road and the area characteristics. Reported Extent: All roads eligible for federal aid, including ramps, and optional for other roadways. Federal aid-eligible roads include urban roads classified as minor collectors or above (functional system 1-6) and rural roads classified as major collectors or above (function system 1-5).
ADOT 2024 National Highway System (NHS)

This dataset represents the roadway sections that comprise the Arizona portion of the National Highway System (NHS), as reported in the 2024 Highway Performance Monitoring System (HPMS) federal report. The NHS is designated by the Federal Highway Administration (FHWA) and consists of roadways important to the nation’s economy, defense, and mobility and include interstates, Strategic Highway Network (STRAHNET) routes and connectors, and other roads that connect major multimodal transportation hubs, such as airports, ports of entry, railroad stations, and other major transportation and business features. For more information, refer to the [ADOT Glossary - NHS page]. Reported Extent: All applicable roadways
ADOT 2024 Pavement Conditions

The annual Highway Performance Monitoring System (HPMS) federal report requires states to collect data on pavement conditions on all state owned roads (i.e. the State Highway System) and a sample of additional roads selected by the Federal Highway Administration (FHWA), also known as sample panels. Each year, ADOT contracts vans equipped to measure the amount of cracking, faulting, rutting, and roughness across all required roadways. Per HPMS requirements, these data are summarized and reported in tenth of a mile sections, known as HPMS bins. In addition to reporting specific pavement conditions, ADOT also calculates the overall condition of the pavement within each bin and reports it on a good, fair, or poor rating scale. For more information about HPMS pavement collection and bin requirements, refer to the [HPMS Field Manual, Item 47 IRI] under the Guidance section. To learn more about how ADOT collects pavement condition data, refer to the storymap [Pavement Data: An Overview]. Reported Extent: State Highway System (i.e. all ADOT-owned roads) and all sample panel roads. Sample panel sections are any roadways, or parts of roadways, that were identified by the Federal Highway Administration (FHWA) as requiring additional data to be reported in the 2024 HPMS report.
ADOT 2024 Functional System

The Federal Functional System designation (FSystem) defines the level of service of a road to the state roadway system. FSystem allows state and local government agencies to classify roadways based on function, destination, design, context, topology, and quantitative mileage and essentially represents the overall importance of a roadway. It is especially important for determining federal funding distribution as only urban roads classified as minor collectors or above (FSystem 1-6) and rural roads classified as major collectors or above (FSystem 1-5) are eligible for federal aid. These roads are collectively known as the Federal Aid Network. The ADOT Functional System layer categorizes roads into seven (7) different classifications, including interstates (FS 1), freeways (FS 2), other principal arterials (FS 3), minor arterials (FS 4), major collectors (FS 5), minor collectors (FS 6), and local roads (FS 7). Whether the route is located in an urban or rural area is determined by the Urban Code event layer, also located within this HPMS feature service. Every public road in the state must be classified under one of these classes. To learn more about FSystems, refer to the [ADOT Federal Functional Classification website]. Reported Extent: All federal-aid eligible roads, including ramps and frontage roads, and optional for all other roads. Federal aid-eligible roads include urban roads classified as minor collectors or above (functional system 1-6) and rural roads classified as major collectors or above (function system 1-5). Within this layer, roads that have a zero, null, or missing FSystem value can be considered a local route (FS 7).
ADOT 2024 Carriageway

ADOT created the carriageway event layer to help track specific information about a rodway, including the roadway type, whether the road is divided or undivided, cardinality, direction of travel, and more. This layer is a custom layer developed specifically by ADOT and is not part of the Highway Performance Monitoring System (HPMS) federal report. However, this layer is used to help calculate values required for HPMS. Reported Extent: All public roads.
Existing Land Use for Maricopa and Pinal Counties, Arizona, 2022

The Existing Land Use (EXLU) dataset represents land use in Maricopa and Pinal Counties, Arizona. This dataset was created as a joint effort of MAG and MAG member agency staff. This dataset serves as a land use inventory and is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling. Because of the level of generalization involved in creating this dataset, land use boundaries may not be accurate representations of ground conditions if used at small scales. These data were developed primarily from assessor parcel data collected in July 2022 for both Maricopa and Pinal Counties.
Arizona Imagery 2019 (NAIP)

The National Agriculture Imagery Program (NAIP) is a federal program which acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition.
