In　view　of　the　characteristics　of　crowd　movement　in　rail　transit,　a　navigation　field　is　introduced　on　the　traditional　social　force　model　to　build　a　crowd　simulation　system,　in　which　the　social　force　model　is　responsible　for　the　interaction　of　pedestrian　with　pedestrians　and　the　environment　around　them,　while　the　navigation　field　is　responsible　for　the　pedestrian＇s　path　planning　in　the　rail　transit.　Compared　with　the　traditional　social　force　model,　it　is　possible　to　avoid　the　＂jitter＂　or　the　local　congestion　caused　by　the　unreasonable　setting　of　the　intermediate　target　point.　Based　on　the　above,　a　crowd　simulation　system　is　developed　for　rail　transit　and　the　Beijing　Zoo　Subway　Station　is　used　as　experimental　scenario.　The　experimental　results　show　that　there　is　no　＂jitter＂　or　partial　congestion　during　the　simulation.　This　method　is　suitable　for　crowd　simulation　in　rail　transit.　©　2018,　Editorial　Department　of　Journal　of　Beijing　Jiaotong　University.　All　right　reserved.
