Abstract With the rapid development of economy, early expressway in our country is facing with reconstruction and extension. The expressway alignment, as the skeleton of expressway, is an important guarantee for the safety of the vehicle driving. Therefore, road alignment evaluation is a major content in the extension of the expressway. In this paper, on the basis of evaluation method of expressway alignment, with the combination of domestic and foreign research experience, the expressway alignment is evaluated from three aspects: continuity, comfort and safety, and the alignment adaptability evaluation system is established through principal component analysis (PCA). At last, the applicability of the adaptability model is tested and verified for the alignment adaptability evaluation of Beijing Shijiazhuang expressway.
