"Urban street networks with higher average node degrees remain significantly more robust and efficient across centrality-based, elevation-based, and random disruption events."
"Conversely, urban street networks with higher chokepoint scores consistently exhibit significantly lower robustness and efficiency across all three disruption types."
"Overall, this study’s results make theoretical sense."
