Description:

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




Annual Average Daily Traffic (AADT) is used to represent all 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.




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.

Description:

The Annual Average Daily Traffic (AADT) for sections of roads for Single Unit trucks reported in the 2024 Highway Performance Monitoring System (HPMS) federal report.




Annual Average Daily Traffic (AADT) is used to represent single unit truck 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 single unit truck 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 meet the FHWA vehicle classification 4 through 7 definitions. Refer to the ADOT Vehicle Classification page for more information.




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.

Access control refers to the ability for vehicles to enter and exit a roadway. Full access control indicates limited access to a roadway, such as through ramps. Partial access control are roads with at-grade intersections but limited to no access directly from private driveways, such as the US 60 between Phoenix and Wickenburg. No access control indicates full access to the roadway, such as directly from private driveways. Refer to the HPMS Field Manual, Item 5 'Access Control' for more details and examples.

Description:

The Administrative layer identifies if a road is restricted from public travel, such as service-only roads or roads blocked by a barrier, such as a gate. This layer includes roads used for travel around parking lots and non-passable roads (such as roads that require four-wheel drive), and centerlines that are not actually a road. The majority of the roads in HPMS are identified as non-administrative, meaning they are open to public travel. Any other value would identify them as restricted roads, which are not included in the Certified Public Mileage calculation.




Reported Extent: All principal arterials (functional system 1-3) and sample panel sections. 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. Values may be available for other roads but are not actively maintained.

Name: AuxiliaryLane_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Auxiliary lanes refer to short portions of the roadway, typically no longer than two intersections, that move in the same direction of travel as through traffic and assist with speed change, turning, weaving, truck climbing, maneuvering of entering and leaving traffic, and other purposes supplementary to through-traffic movement.




Reported Extent: All principal arterials (functional system 1-3) and sample panel sections. 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. Values may be available for other roads but are not maintained.

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Number of lanes open to traffic moving in the counter-peak direction during the peak traffic hour, as determined through measurements using traffic counter devices, such as Automatic Traffic Recorders (ATR) and short term counters using tubes. For example, if the peak hour is during the morning rush hour when the majority of the traffic is moving towards a city center, the counter peak lane event layer would identify the number of lanes available for traffic moving away from the city.




Reported Extent: All sample panel sections. 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. Values may be available for other roads but are not actively maintained.

Layer: CurbAndGutter_2024 (14)


Name: CurbAndGutter_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Curbs are stone or concrete edging along a road. Gutters are designed to allow the flow of water into sewer systems.




Reported Extent: All public roads. Curbs and gutters are coded differently for undivided and divided highways.




For undivided highways, where there is no physical barrier between opposing lanes of traffic, the location of curbs and gutters are recorded only on the cardinal direction roadway. In this case, a curb or gutter located on the 'right' side of the road indicates a feature on the right shoulder of the cardinal roadway. Curbs or gutters on the 'left' side of the road indicate features on the right shoulder of the opposing traffic lanes (i.e. non-cardinal roadway).




For divided highways, curbs and gutters are recorded on both the cardinal and non-cardinal roadway records. In this case, on the cardinal roadway, a curb or gutter recorded on the 'right' side indicates a feature on the right-shoulder of the cardinal-direction roadway while a curb or gutter on the 'left' side indicates a feature on the left shoulder of the cardinal-direction roadway. The same is true for the non-cardinal direction roadway. Note: cardinal direction refers to the direction of increasing mileposts.

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description:

Engineering stations are used as calibration points when building projects, allowing for engineering quality accuracy when entering project information into the Arizona Transportation Information System (ATIS), which is ADOT's GIS system of record for roadway data. They are measured in feet from the beginning of a roadway, or milepost zero of the cardinal direction roadway. Note: cardinal direction refers to the direction of increasing mileposts.




Engineering stations are reviewed and updated with each new roadway construction project. To keep stations as consistent as possible along a roadway, station equations may be used to convert stationing from one measurement value to another on the same alignment.




Reported Extent: Engineering stations are recorded from construction plans for all projects that have completed and are open-to-traffic.

Layer: FacilityType_2024 (20)


Name: FacilityType_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Layer identifies the operational characteristic of a roadway, including if the roadways is a one-way road, two-way road, ramp, non-inventory road, or unbuilt section of road. Non-inventory indicates the non-cardinal route on a two-way roadway. For example, on a two-way roadway, the cardinal direction would be coded a 2 (two-way road) while the opposing lanes of traffic (i.e. non-cardinal direction) would be coded a 6 (non-inventory road). Note: cardinal direction refers to the direction of increasing mileposts.




Reported Extent: All federal-aid eligible roads, including ramps. 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).

Layer: FunctionalSystem_2024 (21)


Name: FunctionalSystem_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

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).

Layer: Milepost_2024 (28)


Name: Milepost_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description:

Locations of milepost markers along the State Highway System. Mileposts are used to assist with identifying specific locations along a roadway, such as directing maintenance crews to portions of a roadway in need or repair.




Note, while ADOT makes every attempt to place mileposts at accurate mile locations, landscapes and other factors may require the markers to be placed slightly off from their true locations. It is recommended that mileposts not be used in projects that require high location accuracy. In those cases, engineering stations may be a more suitable alternative.




Reported Extent: Required for the State Highway System (i.e. all ADOT-owned roads). Optionally recorded for all other roadways.

Layer: PavementConditions_2024 (34)


Name: PavementConditions_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

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.

Layer: ThroughLanes_2024 (54)


Name: ThroughLanes_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

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).

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

The pavement material type for the segment or roadway. The SurfaceType field uses a coded value to identify the general surface type, such as asphalt, concrete or other. The SurfaceTypeComment field lists more specific information about the surface material. The primary source for these data are construction plans. Where construction plans are not available, other sources of information may be used, such as aerial imagery.




Reported Extent: All sample panel sections. 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. Values may be available for other roadways.
