T-shaped　passage　is　one　of　the　most　important　facilities　in　urban　rail　transit　station,　and　the　crowded　phenomena　always　appear　during　peak　hours.　Mixed　pedestrian　flow　in　T-shaped　passage　may　generate　some　conflicts,　which　causes　a　lot　of　delays　for　passengers.　For　reducing　conflicts　and　improving　efficiency　in　T-shaped　passage,　we　designed　the　walking　lanes　for　mixed　pedestrian　flow　with　different　origins　(Os)　and　destinations　(Ds),　and　the　preference　strength　was　proposed　to　perform　lane-design　rule.　A　cellular　automata　(CA)　based　pedestrian　simulation　model　with　the　lane-design　was　built,　and　we　simulated　the　mixed　pedestrian　flow　with　the　effect　of　lane-design　on　the　platform　of　MATLAB　software.　Simulation　results　indicate　that　pedestrian　conflicts　were　reduced　and　the　efficiency　of　passing　was　improved.　Reasonable　lane-design　was　useful　for　mixed　pedestrian　flow,　and　it　could　provide　technical　support　for　the　planning　and　design　of　pedestrian　facilities.　(c)　2021　Elsevier　B.V.　All　rights　reserved.
