An　effective　transportation　organization　is　one　of　key　factors　to　successfully　hold　a　large-scale　public　activity,　and　the　ground　public　transportation　organization　is　important.　In　this　paper,　micro-simulation　software　Vissim　and　Legion　are　used　to　simulate　the　ground　public　transportation　organization　of　the　Workers＇　Gymnasium　in　Beijing　Olympic　Games,　finding　that　the　audience　arrival　to　the　stop　is　too　concentrated　and　that　the　traffic　jam　is　very　severe　when　buses　pull　in　and　out　of　the　stop.　Some　proposals　are　suggested　to　solve　these　problems,　such　as　suitably　increasing　the　walk　distance　of　audiences　and　extending　the　stop　platform.　Simulated　results　indicate　the　proposals　effectively　improve　the　efficiency　of　public　transportation　system　and　the　service　level　for　pedestrians.
