An Extended and Updated Technical Evaluation of Wig-Wag Signs at the A83 Rest and be ThankfulPublished02/02/2017ISBN978-1-910377-74-1AuthorM G Winter and B ShearerPages41ReferencePPR743
The Scottish Road Network Landslides Study made a number of recommendations for landslide management and mitigation. Amongst these was that ‘wig-wag’ signs could be suitable at sites with specific conditions, particularly those sites at which debris flow events occur on a regular basis. Such signs incorporate a standard rockfall/landslide red warning triangle, flashing lights, and a sub-plate that that warns of ‘Higher risk when lights flash’. This report details the results of a trial of such signs; the evidence presented supports the continued use of the wig-wags and the continued promulgation of messages about desired behaviours to the non-local driver target audience.
