Optimization of the emergency disposal process of expressway tunnel accidents based on ExtendSim

Abstract:
After the accident on the expressway tunnel, how to rescue timely and effectively is the key to prevent the secondary accidents and reduce personnel casualties. Combined with the features of expressway tunnel accidents and emergency rescue, the emergency disposal process of expressway tunnel accidents is simulated with the ExtendSim simulation software in this paper. We find out the key factors affecting the efficiency of emergency response, optimize the emergency disposal process from the aspects of the structure and execution technology, and compare and analyze the disposal time and utilization rate of the emergency disposal process before and after optimization. The simulation results confirm that the efficiency of the optimized emergency disposal process is improved by 7.28%, which is effective and feasible.
