摘　　要：通过对高速公路互通变速车道设计方法及标准的对比分析,研究《AASHTO规范》与我国规范的差异。经过分析,《AASHTO规范》对变速车道长度的定义较中国规范复杂,在设计应用时,需参考主线及匝道设计车速,并且根据匝道平曲线要素对变速车道长度进行调整,设计过程更为动态灵活,同时设计方式也较为复杂。Based on the comparison and analysis of the design method and standard of highway interchange speed this paper. Thr AASHTO is mo of main line and between AASHTO and Chinese specification was studied in ough the analysis, it points re complex than the Chinese ramp and adjust the speed 1 signing applications, so the design process is out that the definition of speed change lane length in standard, and it is necessary to refer to the design speed ane according to the ramp plane curve elements when de more dynamic and flexible.
