Based　on　the　analysis　of　Beijing　suburb　traffic　accident　data,　the　＇combined　evaluation　factor　of　multiple-unite　linear　regression　method＇　was　used　to　model　the　relationship　of　the　suburb　intersection　traffic　conditions　and　traffic　accident　rates.　The　evaluation　method　of　the　suburb　intersection　traffic　safety　was　provided.　According　to　the　intersection＇s　traffic　saturation,　the　proportion　of　non-motor　vehicles,　vehicle　types,　the　proportion　of　left　turn,　intersection　spacing,　Intersection　types　and　the　separated　level　of　imports　and　so　on,　the　combined　evaluation　coefficient　Q　was　determined,　and　then　the　safety　level　of　the　intersection　was　determined.　Therefore,　this　research　has　the　practical　significance　in　the　reasonable　evaluation　and　optimal　design　of　suburb　intersections.　Copyright　ASCE　2007.
