Evidence theory in highway design safety evaluation studies

Many elements interact and cause traffic accident, in which the design of the road plays an essential part. With one case in Yiwu, we take detailed assessment on safe design elements of the high way by using evidence theory. Research results indicate that interaction between the safety evaluation indexes for highway design significantly impact on traffic safety. The result is expected to be helpful to improve the current situation of highway design and safely. © 2013 Asian Network for Scientific Information.
