摘要

All over the world, earthquakes have been broken up more frequently thanrnever before. The huge disaster of an earthquake challenged the capability ofrngovernment to handle an emergency. The emergency evacuation corridor planningrnwill be more significant for restoration of a disaster area. This paper proposes arnmethodology for the research on carrying capability of a regional earthquakernevacuation corridor based on macro-simulation to prove the availability andrnrationality of a predetermined regional earthquake evacuation plan. The proposedrnapproach includes three processes: 1) Estimate the evacuation demand of thernearthquake affected area and estimate traffic volume of each link and node ofrnroadway network; 2) Confirm the OD-pairs based on the location of shelters and thernpreplanned direction of evacuation; 3) build up the earthquake evacuation networkrnthrough the macro-simulation software, OREMS, as well as input the outcome ofrnprocedure 1) and 2). Evaluate the carrying capability of the preplanned regionalrnearthquake evacuation corridor through evacuation clearance time and averagernevacuation speed which are the output of OREMS. In the end, the proposed approachrnwas employed in the Beijing case and proved the availability and rationality of thernBeijing earthquake evacuation corridor planning.
