Pedestrian　heterogeneity　is　one　of　the　important　factors　affecting　evacuation　efficiency　in　subway　stations.　This　paper　mainly　studies　the　impact　of　pedestrian　heterogeneity　on　evacuation　based　on　simulations.　With　the　help　of　Massmotion,　the　Qingdao　Jinggangshan　Road　subway　station　is　modeled.　The　social　force　model　is　used　as　the　pedestrian　dynamics　model　and　the　minimum　cost　model　is　used　as　the　decision-making　mechanism　of　pedestrian　path　selection.　The　models　are　verified　by　comparing　the　field　data　with　the　corresponding　simulation　data.　Fully　considering　the　impact　of　different　pedestrian　attributes　on　evacuation　efficiency,　pedestrians　are　divided　into　three　categories　with　different　speed　levels　and　three　categories　with　different　body　size　levels.　Simulation　experiments　are　carried　out　by　adjusting　the　proportional　relationship　of　the　number　of　pedestrians　with　different　attributes.　The　simulation　results　indicate　that　the　larger　the　proportion　of　fast　pedestrians　under　the　same　number　of　evacuees,　the　higher　the　evacuation　efficiency　to　a　certain　extent.　The　evacuation　efficiency　could　be　reduced　accordingly　with　the　increase　in　the　proportion　of　pedestrians　with　large　body　sizes.　When　the　pedestrian　density　is　large,　the　impact　of　pedestrian　heterogeneity　on　evacuation　cannot　be　clearly　reflected.　Moreover,　the　quantitative　fitting　relationship　between　evacuation　time　and　pedestrian　quantity　could　be　obtained.　This　paper　provides　a　theoretical　basis　for　the　determination　of　evacuation　strategy　for　the　heterogeneous　crowd.
