Abstract：

This　paper　studied　the　relationship　between　speed　differences　and　crash　rates　using　nine　of　china　freeway＇s　speed　and　accident　data.　Research　shows　that　the　accident　rate　has　correlations　with　the　dispersion　of　speed.　According　to　the　accident　rate　and　speed　scatter　Distribution,　three　kinds　of　models　will　be　carried　out,　analyzing　the　significant　level　of　F,　as　well　as　R2　amendment.　Arrived　at　the　index　distribution　model　of　accident　rate　and　speed　standard　deviation.　©　2010　ASCE.
