Abstract

The statistics analysis and cross-analysis were carried out on the 961 intersection accidents to acquire intersection safety affecting factors to provide a reference to intersection design and renovation. 961 intersection accidents were collected from ten roads of Sichuan, Yunnan and Chongqing between 2007 and 2010.First, the paper analyzed intersection types, alignments, control types, crash types, and crash contributing factors. Second, the paper carried out the cross-analysis between crash types and crash contributing factors. Finally, the paper established the relationship between the design factors, the crash contributing factors and crash types. The statistical analysis results showed that the intersection of mountainous highway need to be further improved in terms of the right-of-way facilities, road alignment etc. The cross-analysis results showed that many intersection crashes could be avoided if the intersection could be reasonably designed, although the crashes were mainly caused by traffic participant's failing to comply with traffic rules.
