Luggage-laden　pedestrians　are　a　common　group　at　transportation　hubs.　However,　there　is　a　lack　of　experimental　research　related　to　the　heterogeneous　crowds　with　luggage　through　subway　exit　gates.　Therefore,　this　study　focuses　on　the　impacts　of　ticket　gate　layout　on　the　movement　of　heterogeneous　pedestrian　flow　with　luggage　through　a　controlled　experiment.　The　variables　involved　in　this　study　comprise　three　layout　types　of　ticket　gates　and　mixture　ratio　of　luggage-laden　pedestrians.　An　open-source　software　(i.e.,　PeTrack)　is　adopted　for　the　extraction　of　pedestrian　movement　trajectories　from　recording　videos.　The　macro　spatial-temporal　movement　distribution　(i.e.,　trajectory　features,　density　distribution　and　movement　time)　and　microscopic　movement　characteristics　(i.e.,　selection　preference　and　queuing　features)　of　pedestrians　are　analyzed.　The　results　establish　that　the　orientation　of　the　ticket　gates　perpendicular　to　the　direction　of　pedestrian　flow　is　advantageous　for　safety　and　efficiency　compared　to　parallel　arrangements.　Under　the　perpendicular　conditions,　the　facility　can　better　adapt　to　an　increased　mixture　ratio　of　luggage-laden　pedestrians,　and　widened　gate　corridors　on　the　far　left　is　useful　to　enhance　efficiency.　Under　the　parallel　conditions,　the　mixture　ratio　of　luggage-laden　pedestrians　markedly　affects　passing　efficiency　and　safety,　and　widened　gate　corridors　at　the　far　end　is　more　favourable.　Additionally,　a　special　movement　pattern　was　observed　during　the　turning　process　of　multi-column　pedestrian　queues,　i.e.,　the　＂skip-level＂　behavior,　leading　to　the　phenomenon　of　＂queue　proliferation＂.　These　results　aim　to　adapt　pedestrian　flow　line　designs　in　subway　station　to　new　conditions,　and　enhance　pedestrian　passage　efficiency　and　safety.
