Analysis on Capacity of Non-Signalized Intersection on Condition of Ice-Snow

Traffic characteristic on the conditions of ice-and-snow road performance is quite complex and that seriously influenced the capacity of non-signaled intersection. This paper comparatively analyzed the critical gap and headway on the condition of ice-and-snow or normal, and then analyzed the capacity of non-signaled intersection by the acceptability gap theory, and put forward the headway modify coefficient and the non-signaled intersection capacity modify coefficient for ice and snow. The results are the complementarities of traffic flow characteristic on ice-and-snow condition, and they are useful for directing setting traffic engineering facilities in the cold zone. http://www.ivypub.org/mt/paperInfo.aspx?ID=3070
