Mixed　traffic　phenomena　are　one　of　the　most　remarkable　characteristics　in　China　cities,　which　can　cause　traffic　congestion　and　accident　in　urban　intersection　in　China.　So　as　to　create　the　appropriate　strategy　of　signal　control　of　the　intersection,　this　paper　presents　a　new　method　to　divide　the　intensity　state　of　the　pedestrians　and　bicycles　in　the　signalized　intersection　crosswalks　of　green　time.　First,　it　analyzes　the　characteristics　of　the　pedestrians　and　bicycles　in　the　intersection　crosswalks　of　green　time,　and　presents　the　new　definition　of　the　pedestrians　and　bicycles　conglomeration.　Then,　in　the　view　of　the　timing　and　spacing　resources　of　the　intersection,　it　presents　the　new　definition　and　the　necessary　of　the　division　of　the　intensity　state　of　the　pedestrians　and　bicycles　in　the　signalized　intersection　crosswalks　of　green　time.　We　choose　three　indexes　as　the　criterion　to　divide　the　intensity　state　of　the　pedestrians　and　bicycles　as　follows:　the　volume　of　the　pedestrians　and　bicycles　under　the　green　time;　the　utilization　proportion　of　the　green　time;　and　the　utilization　proportion　of　the　space　of　the　intersection.　We　choose　the　K-means　cluster　analysis　as　the　method　to　divide　the　intensity　state　into　three　categories　as　follows:　low　intensity　state;　mean　intensity　state　and　high　intensity　state.　Finally,　it　takes　the　Pingleyuan　intersection　of　Beijing　for　example　to　divide　the　intensity　state　of　the　pedestrians　and　bicycles.
