| Abstract: | Interchange is one of the most important structures in the highway system;it is also the significant node of traffic conversion in the road network.In the design stage,analyzing and evaluating the safety of the interchange program is the foundation to ensure the security of later operation.At present,there are some deficiencies in interchange safety evaluation in China.Starting from the problems that frequently appear in the process of interchange design,this paper discusses the key points that that we should pay close attention to in interchange safety evaluation,thus making contributions to the design and evaluation of the interchange. |
