Due　to　various　constraints　(such　as　geological　structures,　ground　facilities　etc.),　there　are　some　rather　long,　narrow,　and　snake-shaped　transfer　channels,　most　of　which　are　facilitated　with　stairways　and　escalators,　in　the　current　subway　network　in　Beijing.　Such　transfer　channels　are　often　congested　during　peak　hours,　thus　increasing　accident　probability.　The　approach　proposed　in　this　paper　attempts　to　promote　passenger　rational　behavior　by　providing　the　information　reflecting　the　passenger　flow　states　of　the　channel　to　be　entered.　First,　the　passenger　flow　distribution　was　determined　based　on　the　statistical　data.　Second,　the　suitable　representation　form　was　developed　for　each　state　of　passenger　flow　in　transfer　channels　on　the　basis　of　a　survey　conducted　with　a　well-designed　questionnaire.　©　2011　ASCE.
