Road Ranger
Better roads through better data.
Road Ranger is Westwood AI's autonomous highway inspection platform, developed in collaboration with the Michigan Department of Transportation. It delivers pavement condition data, asset inventory, and road anomaly detection at highway speeds — without lane closures.

What Road Ranger
delivers
Road Ranger combines vehicle-mounted imaging arrays, AI pavement analysis, and LiDAR-based asset detection to replace labor-intensive manual inspection programs. The result: more frequent surveys, consistent data quality, and actionable reports that integrate directly into MDOT's asset management systems.
High-Speed Pavement Imaging
Vehicle-mounted line-scan cameras capture full-lane pavement imagery at highway speeds — enabling network-wide surveys in hours, not weeks.
AI Pavement Distress Classification
Deep learning models identify and classify cracking, rutting, raveling, pothole formation, and joint deterioration — aligned with MDOT and FHWA pavement condition standards.
Road Asset Inventory
LiDAR and camera fusion detects and inventories roadside assets — signs, guardrails, delineators, lighting, and drainage structures — with GPS coordinates and condition ratings.
3D Profile & IRI Measurement
Inertial profiling systems measure International Roughness Index (IRI) continuously — providing the ride quality data required for federal reporting and project prioritization.
GIS-Ready Data Outputs
All survey data is georeferenced and exported in formats compatible with MDOT's GIS and asset management systems — no post-processing middleware required.
Annual Network Coverage
Designed to support MDOT's annual pavement condition reporting requirements across Michigan's state highway system — thousands of centerline miles per survey cycle.
Who uses Road Ranger
State Highway Network Inspection
Annual pavement condition surveys across Michigan's state trunkline system — supporting federal HPMS reporting and capital program prioritization.
Local Agency Support
County road commission and municipal street inspection programs — delivering consistent data quality at a fraction of the cost of traditional survey crews.
Construction Quality Assurance
Pre- and post-construction surveys verifying that pavement condition meets contract specifications — reducing disputes and protecting agency interests.
Bridge Approach & Transition Monitoring
Frequent monitoring of bridge approach slabs, deck overlays, and transition zones — high-maintenance locations that benefit from increased inspection frequency.
Emergency Damage Assessment
Rapid post-event surveys following severe weather, flooding, or infrastructure failures — providing decision-makers with verified damage data quickly.
Maintenance Needs Identification
Data-driven identification of preventive maintenance candidates — crack sealing, micro-surfacing, and edge repairs — before they escalate to full reconstruction.
