| Abstract: | Inthis paper, we first study the specific properties of some reflectiv products selected in designing the road safety facility systems for jingtong Expressway,the pirnciple for product selection is decided in the light of the specific conditions of jingtong Expressway. The reflective sheeting characteristics and its constitutional form are discussed. By calculating and comparing some kinds of post stiffness of W Guardrail, the principle for guardrail post shape selection is decided. The analytic method for soloving the equations of parabola shape used in the guardrail extremity and the guardrail break for Energency Telephone is obtain, two designing examples of parabola shape and analytic methods are given. |
