Description: <p>The Annual Average Daily Traffic (AADT) for sections of roads for all vehicle types reported in the 2023 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. <br /><br /><b>Reported Extent:</b> 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. For undivided highways, which do not have a physical barrier between the two directions of traffic, values are reported as the sum total for both directions of travel. On divided highways, AADT is reported separately on the cardinal and non-cardinal directions of the roadway. Note, the cardinal direction refers to the direction of increasing mileposts.<br /><br /><b>Key Terms:</b><br />ADOT, MPD, 2023, HPMS, 2023 HPMS, Traffic Volume, Traffic Count</p>

Name: Carriageway_2023

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Has Views: true

Source Schema Changes Allowed: true

Description: 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.

IMPORTANT: The Facility Type event layer should continue to be used to identify the inventory direction of a roadway (e.g. one-way or two-way roadway).

Reported Extent: All public roads.

Layer: CounterPeakLanes_2023 (12)


Name: CounterPeakLanes_2023

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 YEAR HPMS report. Values may be available for other roads but are not actively maintained.

Layer: CurbAndGutter_2023 (14)


Name: CurbAndGutter_2023

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.

Description: <p>Federal Functional Classification (FFC) defines the level of service of a road to the state roadway system and is an integral part of the annual Highway Performance Monitoring System (HPMS) federal report. FFC 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. FFC is especially important for determining federal funding distribution as only urban roads classified as minor collectors or above (FFC 1-6) and rural roads classified as major collectors or above (FFC 1-5) are eligible for federal aid. These roads are collectively known as the Federal Aid Network. The ADOT Functional Class layer categorizes roads into nineteen (19) different classifications, including interstates, freeways, other principal arterials, minor arterials, major collectors, minor collectors, and local roads, each separated by an urban or rural designation based on their location according to the <a href="https://experience.arcgis.com/experience/004a3b98c8c04c48a38184929977c360/?block_id=layout_958_block_7" target="_blank">2013 adjusted urban area boundary</a>. The adjusted urban area boundary is an expansion of the 2010 urban areas identified by the U.S. Census Bureau but adjusted to suite transportation planning needs. Every public road in the state must be classified under one of these classes. <br /><br /><b>IMPORTANT:</b> The Federal Highway Administration (FHWA) uses a new seven-class system, referred to as Functional System, that removes the urban and rural separation. Before submitting their HPMS report, ADOT converts the functional classification codes (1-19) to FHWA function system codes (1-7). Refer to <a href="https://experience.arcgis.com/experience/004a3b98c8c04c48a38184929977c360/?block_id=layout_958_block_13" target="_blank">Coding Changes</a> to learn more about the conversion. To read more about functional classification, review the <a href="https://arcg.is/1L4rDD0" target="_blank">ADOT Functional Classification website</a>. <br /><br /><b>Reported Extent:</b> 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 classifed as major collectors or above (function system 1-5).<br /><br /><b>Key Terms:</b><br />ADOT, MPD, 2023 HPMS, 2023, HPMS</p>

Layer: Milepost_2023 (29)


Name: Milepost_2023

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: <p>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. <br /><br /><b>Reported Extent:</b> Required for the State Highway System (i.e. all ADOT-owned roads). Optionally recorded for all other roadways.<br /><br /><b>Key Terms:</b><br />ADOT, MPD, 2023 HPMS, 2023, HPMS</p>

Description: <p>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 <a href="https://www.fhwa.dot.gov/policyinformation/hpms/fieldmanual/page06.cfm#toc249159736" target="_blank">HPMS Field Manual, Item 47 IRI</a> under the Guidance section. To learn more about how ADOT collects pavement condition data, refer to the storymap <a href="https://arcg.is/zuKH80" target="_blank">Pavement Data: An Overview</a>. <br /><br /><b>Reported Extent:</b> 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 2023 HPMS report.<br /><br /><b>Key Terms:</b><br />ADOT, MPD, 2023 HPMS, 2023, HPMS</p>

Description: <p>Percent Peak Single Trucks is the percentage of the total AADT that is single unit truck traffic during the peak traffic hour, as determined through measurements using traffic counter devices. The value is calculated by dividing the total combination truck traffic during the peak hour by the AADT for all vehicle types. Annual Average Daily Traffic (AADT) represents the average traffic expected on a typical day of the year. Single unit trucks are any trucks that meets the requirements established for the FHWA Truck Classification Method for Categories 4 through 7. Refer to the Federal Highway Administration website for more information about <a href="https://www.fhwa.dot.gov/policyinformation/tmguide/tmg_2013/vehicle-types.cfm" target="_blank">truck classifications</a>. <br /><br /><b>Reported Extent:</b> 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 2023 HPMS report. Values may be available for other roads but are not actively maintained.<br /><br /><b>Key Terms:</b><br />ADOT, MPD, 2023 HPMS, 2023, HPMS</p>
