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,　community＇s　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.
