A Cell-Based Regional Evacuation Model with Contra-Flow Lane Deployment

Article Preview

Abstract:

Based on SO-DTA and one-destination evacuation, a cell-based regional evacuation model, which embeds CTM and point-queue model, is proposed in this paper. The road network is converted to the cell-node topology structure so as to reduce the constraints. The “traffic holding” problem also be solved in the model by an OSP constraint. And to improve the evacuation efficiency, contra-flow lane is imported. A numerical experiment is conducted to verify the proposed model and algorithm.
