Abstract:Based on the data collected at several freeways in China,it is clear that the current freeway operation is not as safe as it should be.Comparing to other developed countries,the freeway traffic fatality rate is much higher.Through detaiLED comprehensive data analysis,this paper examines the distributions of crash type,crash frequency by time and space,crash violation and crash causes.Many of unique characteristics of traffic crashes on freeways in China will be discussed.

Key words:freeway safety;crash data;crash characteristics;crash distribution
