The　location　method　of　emergency　evacuation　signs　in　large　pedestrian　facilities　was　presented,　in　order　to　ensure　the　spatial　and　temporal　continuity　of　signs　indication　in　pedestrian　emergency　evacuation.　Considering　the　geometry　characteristics　of　regular　triangle,　the　radius　and　ratio　of　signs　service,　the　distance　of　pedestrian　evacuation　and　the　chain　cluster　of　evacuation　route,　two　methods　of　＂filling　with　tangent-circles＂　and　＂setting　at　hinge　node＂　were　introduced　to　locate　evacuation　signs　respectively　in　no-obstacle　and　existing-obstacle　pedestrian　facilities.　The　computation　of　the　chain　cluster　of　evacuation　route　and　the　labeling　of　hinge　node　in　pedestrian　facilities　were　carried　out　based　on　the　partitioning　of　cellular　automaton　and　the　shorter　path　search.　Through　two　cases,　the　procedure　of　the　location　of　emergency　evacuation　signs　was　presented　in　pedestrian　facilities　with　and　without　evacuation　obstacles.
