How to Assess Intersections and Turning Geometry

Intersection assessment evaluates whether the load can navigate turns safely while maintaining lane position.

Read time: 5 min

Intersection analysis for OS/OW loads focuses on:

**Physical Geometry** - Corner radii and curb lines - Lane widths approaching and through intersection - Median barriers and islands - Traffic signal and sign pole locations - Utility poles and guy wires near corners

**Turning Analysis** - Required encroachment into opposing lanes - Trailer tracking through the turn - Rear overhang sweep path - Front overhang clearance

**Traffic Control** - Signal timing (can load clear intersection in one cycle?) - Turn restrictions by time of day - Traffic volumes during planned move time

**Documentation** - Measure and photograph corner radii - Note lane widths with photos - Identify all fixed obstacles within sweep path - Document any modifications needed (traffic control, signage removal)

For complex intersections, consider swept path analysis using load-specific turning templates.
