| Abstract: | The geometrical design of linearity is specially required by the restriction of some control factors in the design of highway line and interchange linearity.The article introduces the detail problems in the shortage of sight distance design occurred in the expressway engineering design cases,and focuses setting forth on some special treatment methods able to use for ensuring the sight distance when the enhancement of the linear index is limited. |
