10 Toolbox: Analysis of trend in displacement This is based on Theil-Sen linear trend detection algorithm. Route 600 slope (using SqueeSAR data in 2014) [Red = critical, Yellow = warning, Green = safe]* *Thresholds were chosen to match field observations of Brian Bruckno, Ph.D., P.G., VDOT TRB 2016 Workshop

11 Toolbox: Pavement smoothness analysis The smoothness value of an area indicates the uniformity of displacements for InSAR displacements on the road. Graph signal processing method *Thresholds were chosen to best separate (Very Poor, Poor) from (Fair, Good) from Excellent in CCI TRB 2016 Workshop
