In　recent　years,　natural　and　human　related　disasters　have　occurred　frequently　in　China.　Due　to　these　unfortunate　events,　there　have　been　tremendous　losses　of　property　and　lives.　Natural　and　man-made　disasters　have　made　transportation　evacuation　become　a　major　concern　that　emergency　agencies　need　to　consider　in　their　emergency　management.　Emergency　management　plans　should　be　able　to　ensure　the　safety　and　quick　movement　of　people　at　the　time　of　crisis.　It　is,　however,　impossible　to　conduct　experiments　in　the　field　to　represent　scenarios　of　emergency.　Therefore,　simulations　are　used　to　approximate　emergency　conditions.　This　paper　presents　an　urban　emergency　transportation　simulation　system　based　on　PARAMICS　and　its　applications　for　Beijing　metropolitan　area.　The　proposed　system　(called　MEETSIM)　can　be　used　to　simulate　movements　of　vehicles　and　pedestrians　under　emergencies　based　on　the　behavior　analysis　conducted　through　the　simulator.　Moreover,　the　proposed　system　has　put　the　entire　process　of　evacuation　under　the　hypothetical　emergency　event　into　consideration.　The　development　of　this　package　has　demonstrated　its　effectiveness　for　producing　evacuation　routing　strategies,　optimizing　emergency　resource,　identifying　total　evacuation　time,　and　evaluating　the　performance　of　evacuation　operations.　©　2010　ASCE.
