Based　on　the　basic　characteristics　of　emergency　process,　a　three-layer　systematic　method　for　emergency　evacuation　road　net　planning　was　presented　in　this　paper.　It　is　proposed　a　full　synthetical　framework　for　emergency　evacuation　planning,　which　integrates　key　traffic　technologies　such　as　emergency　route　choice　and　traffic　control　as　main　measures　to　improve　emergency　evacuation　plan.　It　is　hopeful　to　optimize　roads　and　traffic　resources　under　emergency,　to　set　down　rational　traffic　evacuation　strategy,　and　to　provide　technological　support　for　constituting　emergency　evacuation　plan.　According　to　traffic　demand　forecasting　of　Beijing　2008　Olympic,　the　paper　depicted　the　planning　method　in　detail　by　taking　Beijing　Olympic　Park　emergency　evacuation　as　a　case　study.
