Shengxue Zhu, Jian John Lu, Qiaojun Xiang, Linli Yan · 2009
In order to objectively evaluate the traffic safety performance of intersection, this study puts forward an intersection safety evaluation model based on BN which treats the expertspsila different opinions effectively, and obtains reasonable results even without certain expertspsila opinions. Then the paper presents the topological structure of the model and the reasoning process of aggregating expertspsila experiences and knowledge. Finally the paper evaluates an intersection with the model to show that it diagnoses and analyses the intersection safety conveniently which neednpsilat the traffic accident statistical data and traffic conflict survey.
