To　study　and　analyze　the　impact　of　the　implementation　of　the　rail　transit　reservation　mechanism　on　passenger　travel　efficiency,　this　paper　simulated　and　deduced　the　whole　process　of　passengers　riding　rail　transit,　the　Changping　Line,　where　the　Shahe　Station　was　located　in　the　morning　rush　hour　pilot　station　of　Beijing　rail　transit,　was　selected　as　the　research　object,　and　the　case　analysis　was　carried　out　by　obtaining　the　automatic　fare　collection　(AFC)　card　swipe　data　and　train　operation　scheme.　Results　show　that　compared　with　the　conventional　queuing　method,　the　booking　mechanism　can　effectively　reduce　the　queuing　time　outside　the　station,　and　with　the　increase　of　the　proportion　of　the　number　of　booking　passengers　to　all　passengers,　the　reduction　effect　of　waiting　time　outside　the　station　is　more　significant.　At　the　same　time,　the　full　load　rate　of　corresponding　trains　can　be　improved.　This　is　because　some　passengers　waiting　outside　the　station　can　be　adjusted　to　enter　the　station　at　other　times,　which　improves　the　utilization　rate　of　train　resources,　and　scatters　passenger　demand　to　a　certain　extent,　but　the　premise　is　that　some　passengers＇　travel　habits　will　be　changed.　The　simulation　results　can　provide　theoretical　support　for　the　implementation　of　larger　scale　reservation　mechanism　in　metro　rail　transit　stations.　©　2024　Beijing　University　of　Technology.　All　rights　reserved.
