摘要：	This report presents a study that has investigated the issues of mounting signs on concrete safety barriers in the central reserve. The design of concrete safety barriers causes problems for the mounting of existing temporary traffic management signs since traditional sign mounting ‘A’ frames are considered to be unsuitable due to the height of the safety barrier. ‘A’ frames (which generally straddle the barrier) cannot touch the ground without modification. Various solutions to these problems have been investigated and are described in this report. This report outlines the research and comprises four main areas: • A study that has assessed current practice for mounting Temporary Traffic Management (TTM) signing on Vertical Concrete Barriers (VCB)’s. Current practices include the use of conventional sandbags plus webbing straps which tie sign frames to adjacent road furniture. • A survey of TTM experts to gauge current opinions on the subject. Those consulted include Highways Agency Area Teams, the Traffic Management Contractors Association, Britpave, manufacturers of concrete barriers, and sign frame manufacturers. • A questionnaire based survey of Highways Agency Area teams to establish the different types of permanent traffic sign located in the central reserve on the motorway and major trunk road network. • A description and discussion of the various available solutions and recommendations for both permanent and temporary traffic management signs.
