Metro　station　is　a　densely　populated　place,　and　it　is　easy　to　cause　serious　casualties　in　emergencies　such　as　fires.　Reasonable　emergency　guidance　system　can　improve　pedestrian　evacuation　efficiency　and　escape　rate　in　emergency　environment.　In　this　paper,　a　virtual　reality　pedestrian　simulation　experiment　platform　is　built　by　immersion　virtual　reality　technology,　which　can　obtain　pedestrian＇s　psychological　changes　in　emergency　situations　and　improve　the　experiment.　Based　on　the　virtual　reality　platform,　pedestrian　evacuation　experiments　in　emergency　situations　were　designed.　In　this　paper,　the　fire　scenario　of　a　subway　station　in　Beijing　is　taken　as　an　example　to　optimize　the　design　of　the　guidance　system　of　the　subway　station.　Through　the　way　of　objective　data　output　and　virtual　reality　experience　of　the　experimenters,　the　existing　problems　of　the　induction　system　are　analyzed,　and　new　optimization　schemes　are　put　forward　and　compared.　©　ASCE.
