摘要：

The　concept　＇Safety　Influencing　Range　of　Freeway　Interchange＇　was　defined　in　this　paper.　The　highway　accident　distribution　was　studied　by　taking　500　m　and　100　m　as　the　statistical　unit　separately　in　5　km　range　on　both　sides　of　the　interchange,　and　the　result　indicates　that　it　is　suitable　to　take　500　m　as　statistical　unit,　and　based　on　analyzing　and　comparing　the　accident　frequency　in　and　outside　of　1　km,　2　km,　3　km,　4　km　range　respectively,　the　safety　influencing　range　of　freeway　interchange　was　confirmed.　The　theoretical　accident　percent　distribution　exhibit　was　also　proposed.　The　research　results　can　provide　important　reference　for　safety　analysis　and　accident　prediction　model　establishment　of　freeway.
