Abstract
En 中文
• Hybrid simulation-graph approach identified optimal weight-metric combinations. • W2 weighting scheme with Total Node Strength achieved 96 % correlation accuracy. • Weighted graphs dramatically outperformed unweighted in vulnerability assessment. • Dynamic traffic-informed weighting captured congestion effects better than static.
