At present, there are lack of quantitative evaluation indexes and methods for the expressway alignment consistency at home and abroad. In order to study the method, an eye tracker is used to collect dynamic vision data and vehicular GPS is used to collect actual operation speed. Considering the drivers' visual feelings on the expressway alignment, the video information is used to get the quantitative relationship between the drivers' dynamic vision and vehicles' actual operation speed. Based on the relationship between the rate of expressway accidents and the rate of visual information change, the evaluation model is built, which uses the rate of visual information as the index for evaluating the alignment consistency. In addition, the evaluation model is corrected by the operation speed. The practical engineering applications show that this evaluation model is reasonable and practical. The evaluating results are consistent with the conclusions of related standards.
