| Abstract: | In order to analyze the traffic safety rationality of highway virescence,the traffic safety problems leaded by unreasonable virescence are studied,such as the sight distance affected by medial horizontal curves sections virescence.And the distance between the virescence and it's height in median affect traffic safety too,including the glare prevention,horizontal visibility and botanical survival in the poor growing conditions.At the same time,large radius tree crowns will affect not only the expressway clea... |
