Research on Widening Sight Distance and Minimum Curve Radius of Highways
Due to various factors such as unfavorable geological condition,basic farmland,water conservation district,and ecological red lines,the whole highway cannot all adopt relatively high curve radius,which may lead to poor visibility in the innermost lane of the left curved section.In order to reduce vehicle travelling risk,visual distance inspection is carried out on sections with poor visual visibility,and corre-sponding technical and engineering measures are taken to improve them.A practical minimum curve radius is provided based on comprehensive consideration of design and construction.
