Origin-Destination (OD) matrix from XDR-inferred commuting trips (left). Rows are home municipalities, columns are work municipalities. The matrix on the left is row-normalized and then multiplied by 100 to ease interpretability. The matrix on the right shows the difference with an OD matrix built from the Santiago Travel Survey held in 2012. Each cell in this second matrix is colored with a divergent color palette: grey cells show similar values, orange cells depict OD pairs where XDR infers more trips, and purple cells depict OD pairs where the Travel Survey reports more trips
