abstract="The Traffic Control Products group of the 3M Company initiated a program to study the performance of reflectorized direction signs in London. The study focused on the interaction between the performance of a range of reflective sign-face sheeting and the viewing conditions for motorists. The study aims to quantify the potential benefits of using overall higher performance retro-reflective materials than currently required by the Department of Transport for signage in typical London traffic conditions.<p />",
