To　improve　the　travel　efficiency　of　passengers　and　the　service　level　of　urban　rail　transit,　it　is　necessary　to　study　the　traffic　congestion　index　of　rail　transit　stations.　Combining　field　research　data,　this　paper　categorizes　and　analyzes　a　variety　of　station　facilities　including　flow　limiting　facilities,　security　inspection　equipment,　fare　collection　equipment,　stairway　or　escalator,　passageway　and　platform,　and　the　service　level　of　urban　rail　transit　stations,　to　obtain　a　congestion　evaluation　index　of　different　kinds　of　facilities.　Then　based　on　congestion　index　of　all　kinds　of　equipment　and　facilities,　this　study　determines　the　congestion　index　of　stations　and　the　grade　standard　through　the　weighted　sum　method,　according　to　the　degree　of　passenger　flow　demand　for　equipment.　Finally,　this　paper　analyzes　the　index　and　degree　of　congestion　by　the　example　of　Fuxingmen　Station　in　Beijing.　©　2018　American　Society　of　Civil　Engineers.
