Abstract: | The Critical Cluster Model (CCM) is an optimization model assessing the evacuation risk on the scale of neighborhoods.The static evacuation risk in the CCM is measured by Bulk Lane Demand (BLD)-an index that solely depends on network structure and population of evacuees.The advantage of the CCM is having less input parameters and with relatively smaller computational cost.Moreover,the process of risk assessment by the CCM is a global optimization process.For this reason,the CCM provides a relatively ideal s... |
