Best Practices for Selecting an Area of Interest
Proper Area of Interest selection improves the quality and usefulness of Asphalt Intelligence analysis.
Overview
The Asphalt Intelligence computer vision model works by comparing the trafficked and untrafficked parts of roads and highways within each Area of Interest.
Recommended Practices
- Separate different driving surfaces, such as concrete and asphalt.
- Separate infrequently driven surfaces into their own Areas of Interest.
- Separate heavily shadowed areas into their own Areas of Interest.
- Separate different types of lanes, such as highway lanes and ramps.
- Avoid road clutter, including cars, trees, and other visual obstructions, when possible.
- Make Areas of Interest as large as practical while keeping the surface type consistent.
What to Avoid
- Do not include two different surface material types in the same polygon.
- Do not cross or overlap the polygon boundary.
- Do not combine infrequently driven surfaces, such as shoulders, gores, or driveways, with regular driving lanes.
- Do not include heavily shadowed areas in the same Area of Interest as clearly visible pavement. Draw separate polygons for heavily shadowed areas when needed.
- Do not draw very small Areas of Interest.
Summary
The best Areas of Interest contain one clear pavement surface type, minimal clutter, consistent lighting, and enough roadway area for the model to compare trafficked and untrafficked surfaces.
