Regarding the guarantee traffic safety, the traffic
　　behavior simulation research of road intersection
　　pedestrian has the
　　important meaning. After the investigation and the
　　process of data, communitys movement characteristic
　　of the road intersection
　　pedestrian were summarized, the vehicle speed change
　　tendency of the mobile stream under the pedestrian
　　influence were forecasted,
　　and the simulation to the typical road intersection
　　pedestrian behavior were carried out by using the
　　microscopic simulation software
　　and the governed speed parameter. Finally the road
　　intersection improvement measure was proposed. The
　　findings have the
　　important meaning regarding improving the safety of
　　road intersection.
