7 Industry Standards

Built on proven
industry standards.

Road Triage is developed around the same standards used by state DOTs, federal agencies, and transportation engineers worldwide. This is not proprietary guesswork — it is established methodology, automated.

Standards Compliance

The standards behind every score.

ASTM D6433

Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys

The industry's foundational standard for pavement condition assessment. Defines 19 distinct distress types for asphalt pavements, establishes severity classification criteria (Low, Medium, High) for each distress, prescribes density-based deduct value curves, and specifies the mathematical procedure for computing a Pavement Condition Index.

Road Triage Implementation

Road Triage implements all 19 distress types, their severity thresholds, deduct curves, and the corrected deduct value (CDV) procedure as the core of our RT-PCI scoring and the distress identification framework used across all five scoring methodologies.

ASTM E3303-21

Standard Practice for Generating Pavement Surface Cracking Indices from Digital Images

Establishes objective, reproducible methods for computing cracking condition indices directly from pavement imagery rather than manual field observation. Defines how crack length, width, and area measurements from automated image analysis translate into standardized crack severity and extent metrics.

Road Triage Implementation

Road Triage implements E3303 as the basis of our RT-CCI (Cracking Condition Index), computing aperture-weighted crack indices from AI-powered segmentation and automated crack width analysis applied to vehicle-mounted camera imagery.

ASTM E1778

Standard Terminology Relating to Pavement Distress

The official ASTM vocabulary standard that defines the terminology, classification labels, and definitions for all pavement distress types used in condition surveys. Ensures consistency and unambiguity when communicating distress observations across agencies, systems, and reports.

Road Triage Implementation

Road Triage follows E1778 terminology for all distress classification labels throughout the pipeline — from detection and tracking through scoring and delivery — ensuring that distress names in our reports match the terms recognized by transportation agencies nationwide.

AASHTO R 55

Standard Practice for Quantifying Cracks in Asphalt Pavement Surfaces

The AASHTO standard specifically addressing how cracks in asphalt pavements should be quantified from automated survey data. Defines crack severity classification by measured width (Low below 6mm, Medium between 6mm and 19mm, High above 19mm) and prescribes methods for computing crack density and extent.

Road Triage Implementation

Road Triage applies R 55 width-based severity classification using proprietary image analysis within the Perception Engine to measure actual crack width in millimeters, providing crack quantification data that feeds our RT-CCI scoring and distress statistics reporting.

Ohio DOT DSE

Distress Severity and Extent (ODOT DSE) Rating Methodology

The Ohio Department of Transportation's pavement condition rating methodology using fixed deduction tables indexed by distress type, severity level, and extent category (Occasional, Frequent, Extensive). Produces a 0-100 Pavement Condition Rating used by Ohio and adapted by other state DOTs.

Road Triage Implementation

Road Triage implements the ODOT DSE deduction tables as the scoring methodology for our RT-PCR (Pavement Condition Rating), mapping D6433 distress density into extent categories and applying the corresponding fixed deductions.

Wisconsin PASER

Pavement Surface Evaluation and Rating

A visual pavement rating system developed by the University of Wisconsin Transportation Information Center, producing a 1-10 condition rating widely adopted by over 1,000 municipalities and multiple state DOTs. Designed for practical field use with clear condition descriptions at each rating level tied to recommended maintenance actions.

Road Triage Implementation

Road Triage implements a continuous-weighted adaptation of the PASER methodology as our RT-PASER scoring, translating automated distress type, severity, and density observations into the familiar 1-10 scale that municipalities use for maintenance planning and budgeting.

FHWA HPMS

Federal Highway Administration Highway Performance Monitoring System

The federal framework requiring state DOTs to annually report four pavement condition metrics for every NHS road: IRI (International Roughness Index) for ride quality, cracking percentage for surface distress, rutting depth for structural deformation, and faulting for concrete joint displacement. These metrics drive federal funding allocation under MAP-21 and the FAST Act (23 CFR Part 490). Interstate roads require annual reporting; non-Interstate NHS roads require biennial reporting. Non-NHS Federal-aid roads report via statistical sample panels. Local/municipal roads are exempt from section-level pavement condition reporting. Of the four metrics, only IRI requires certified inertial profiler equipment (AASHTO M328). Cracking, rutting, and faulting can be measured through imaging and other methods.

Road Triage Implementation

Road Triage delivers the cracking percentage metric through automated image-based distress analysis from any vehicle-mounted camera, including smartphone — no profiler required. When equipped with SSI profiler hardware, Road Triage captures all four HPMS metrics from a single survey pass: IRI, rutting, and faulting from the profiler sensors combined with cracking percentage from our image analysis. This provides a complete HPMS-ready dataset for state DOTs reporting on NHS roads, while municipalities can use smartphone collection alone for their local road maintenance needs.

Important Disclaimer

Road Triage assessment scores are modeled after the established industry standards listed above and are intended as decision-support tools. While we strive to follow each methodology closely, automated image-based analysis may produce results that differ from traditional manual field inspections or certified laboratory measurements. Scores should not be interpreted as certified engineering evaluations. Actual field conditions, environmental factors, and image quality may affect results. Users should apply professional judgment when making infrastructure decisions based on Road Triage data.
