A 0–100 score representing the condition of a pavement section. ASTM D6433 is the underlying standard. The headline number every pavement inspector cares about.
D6433 (ASTM D6433)
The US standard for road and parking-lot PCI surveys. Defines sample-unit sizing, 19 AC distress types, 19 PCC distress types, deduct curves, and CDV iteration.
PROWAG
Public Right-of-Way Accessibility Guidelines. The 2023 US standard for accessible sidewalks, curb ramps, and pedestrian routes. Issued by the US Access Board.
ADA
Americans with Disabilities Act. The 2010 ADA Standards Chapter 4 governs accessible routes in private accommodations; 28 CFR Part 35 governs the public sector (Title II).
MUTCD
Manual on Uniform Traffic Control Devices. The US standard for road markings and signs; current is 11th Edition (December 2023).
ICAO Annex 14
International Civil Aviation Organization standard for aerodrome design and operations. Universally adopted outside the US.
ArcGIS
Esri's geographic-information-system platform. Dominant in US municipal and AEC use; very strong in EU. LAIRA outputs to ArcGIS Online or ArcGIS Enterprise customer tenants natively.
Esri
The company that makes ArcGIS. Airwai has a co-marketing partnership with Esri.
AEC
Architecture, Engineering, Construction. The industry segment that buys LAIRA.
Part 139
FAA Part 139 — the regulation that governs commercial airport operations in the US, including pavement maintenance.
Light Detection And Ranging. The sensor that fires laser pulses to measure distances and build 3D point clouds. iPhone Pro and iPad Pro have built-in LiDAR; the LAIRA app uses it.
Point cloud
The 3D dataset LiDAR produces — a collection of points in 3D space, each with x/y/z and (optionally) color and intensity.
GNSS / GPS
Global Navigation Satellite System / Global Positioning System. Used to geolocate every scan. iPhone has consumer-grade GPS; the LAIRA Rig uses survey-grade Septentrio RTK GNSS.
RTK
Real-Time Kinematic. A GPS technique that achieves ~2cm accuracy by using a base-station correction. Standard on the Rig; not available on iPhone.
PAVER
Pavement-management software adopted across DoD, USACE, and many municipalities. LAIRA outputs are PAVER-compatible.
