# Interpreting Relational G-force, X, and Y graphs

<aside> 💡 Tip: The broader traffic context (i.e., road infrastructure, traffic calming measures) should always be considered when interpreting G-force, X-axis, and Y-axis graphs, to determine whether the data output matches known acceptable thresholds at certain speeds.

### Relational G-force graphs

The equation for relational G-force is:

$Relational \space Gforce = \sqrt{x^2 + y^2}$

Where x = acceleration and deceleration, and y = left and right steering. Based on american research, g-force values can be labeled as:

• Harsh braking when G-force value is > 0.6
• Harsh acceleration when G-force value is > 0.4
