All　over　the　world,　earthquakes　have　been　broken　up　more　frequently　than　ever　before.　The　huge　disaster　of　an　earthquake　challenged　the　capability　of　government　to　handle　an　emergency.　The　emergency　evacuation　corridor　planning　will　be　more　significant　for　restoration　of　a　disaster　area.　This　paper　proposes　a　methodology　for　the　research　on　carrying　capability　of　a　regional　earthquake　evacuation　corridor　based　on　macro-simulation　to　prove　the　availability　and　rationality　of　a　predetermined　regional　earthquake　evacuation　plan.　The　proposed　approach　includes　three　processes:　1)　Estimate　the　evacuation　demand　of　the　earthquake　affected　area　and　estimate　traffic　volume　of　each　link　and　node　of　roadway　network;　2)　Confirm　the　OD-pairs　based　on　the　location　of　shelters　and　the　preplanned　direction　of　evacuation;　3)　build　up　the　earthquake　evacuation　network　through　the　macro-simulation　software,　OREMS,　as　well　as　input　the　outcome　of　procedure　1)　and　2).　Evaluate　the　carrying　capability　of　the　preplanned　regional　earthquake　evacuation　corridor　through　evacuation　clearance　time　and　average　evacuation　speed　which　are　the　output　of　OREMS.　In　the　end,　the　proposed　approach　was　employed　in　the　Beijing　case　and　proved　the　availability　and　rationality　of　the　Beijing　earthquake　evacuation　corridor　planning.　©　2009　ASCE.
