From: A road network simplification algorithm that preserves topological properties
Simplification method | Correlation coefficient |
|---|---|
Proposed, centrality estimation | \(\rho\) = 0.964 , R = 0.911 |
Proposed | \(\rho\) = 0.952 , R = 0.883 |
w/o residential roads | \(\rho\) = 0.805 , R = 0.834 |
