Application of the illusion in the design of highway route

摘  要:讨论了与公路几何结构设计密切相关的有关错觉方面的问题。通过对一些错觉方面的图例进行分析后 ,提出 :在进行公路几何结构设计的过程中 ,除了应考虑其它方面的影响因素之外 ,还应注意错觉对公路使用者所产生的影响。特别是在确定与视觉效果密切相关的公路路线几何技术指标时 ,更应该注意这一点。为此 ,对目前中华人民共和国交通部公布的《公路路线设计规范》中有关确定同向曲线间直线段最小长度的条款提出了具体的补充修改建议 ,并对公路路线纵断面设计中一直困扰公路使用者的错觉问题 ,提出了科学、合理、具体。

In the paper,the problems of illusion related highway geometric structure have been discussed.Through the analysis of the figures and drawings about illusion,the authors advance that the influence of illusion on the user of highway need to be considered with much attention as well as other respects taken into consideration when the period of the highway geometric structure is designed,especially when the technical and geometric indices and data of highway closely related to the visual effects are required to determine.Therefore the authors raise a scientific suggestion on the clause of the minimum line length value of the plane curve between two same directed curves in 'Design Specification for Highway Route' published by Transportation Department of the People's Republic of China.Meanwhile,for the problem of illusion,which interferes the user of highway route,the authors advance a scientific and reasonable solution.
