Applicability Analysis and Installation Techniques of Driver Feedback Sign on Freeway in China

Abstract:

The Driver Feedback Sign (DFS) has been widely used abroad to reduce the vehicle speed to improve traffic safety level, but it only be used on a few of freeways and urban expressways in China, and there have no research on its application effect. In order to popularization and application the DFS in China, the paper analyzed the DFS application situation at home and broad by document retrieval, comparatively analyzed implement effect before and after installing DFS on Badaling freeway by vehicle speed survey and questionnaires survey. At last, the paper comprehensively analyzed the applicability of DFS on freeway in China and proposed the installing requirement and technical requirement.
