This　paper　aims　to　measure　the　effect　of　individuals　with　simulated　disabilities　on　evacuation　processes　in　a　room　with　an　exit　through　a　controlled　experiment.　A　total　of　60　individuals　participated　in　the　experiment.　There　are　three　mixed　ratios　(i.e.,　0%,　5%　and　10%)　of　users　of　two　mobility　aids　(i.e.,　wheelchair　users　and　pedestrians　on　crutches　simulated　by　non-disabled　pedestrians　using　auxiliaries).　Video　recordings　and　the　Mean-shift　algorithm　are　employed　to　extract　and　track　pedestrians’　trajectories.　Evacuation　time,　speed,　evacuation　sequence　and　specific　flow　are　analyzed　according　to　the　trajectories.　It　is　discovered　that　compared　with　tests　without　individuals　with　simulated　disabilities,　evacuation　time　in　tests　with　simulated　wheelchair　users　and　pedestrians　on　crutches　increases,　while　the　average　instantaneous　speed　and　specific　flow　decrease.　The　spatial　distribution　obtained　by　the　Nearest-neighbor　analysis　suggests　that　congestion　near　the　exit　formed　slower　in　tests　with　individuals　with　simulated　disabilities.　It　is　found　that　compared　with　tests　without　individuals　with　simulated　disabilities,　crowd　danger　is　higher　in　the　tests　involving　individuals　with　simulated　disabilities,　especially　with　simulated　wheelchair　users.　It　is　hoped　that　this　study　will　be　helpful　in　crowd　management　involving　individuals　with　disabilities.　©　2022　Elsevier　Ltd
