Road Worker Conspicuity Roadworker Conspicuity – Daytime & Nightime – NEW! S. Helman and M. Palmer from TRL released this report for the UK Highways Agency in late 2010. This recent report interviews road workers to gauge their expectations of High-Visibility retroreflective garments and then goes on to survey a large number of participants under realistic test conditions. The study demonstrates that some Hi-Viz safety colours viewed in proximity to response vehicles and against different types of background clutter may have much shorter detection distances than shown previously. In particular this shortfall occurs at night where some visual detection distances can fall to as low as 25 – 45 meters at the roadside.

UK HeavyVehicles Conspicuity Guidelines Application of Retro Reflective Conspicuity Markings to Heavy Vehicles This compliance guide for Conspicuity Markings to Heavy Vehicles was released in February 2011 by the Freight Transport Association in the UK and clearly outlines the new UN ECE conspicuity markings required by the European Union agreements. This is a concise document that illustrates the minimum coverage required for civilian vehicle conspicuity. The new regulations do not require full outline contour markings on the upper side surfaces of the vehicle but a full contour marking set remains essential for all emergency vehicles. The advantages of fluorescent/reflective materials are strongly reinforced, especially the superiority of a solid band of fluorescent colour rather than the red/white alternating pattern found within the US NHTSA conspicuity regulations for trucks. The Canadian Study linked below demonstrates the superiority of a single flourescent colour under different weather conditions Read the UK Goods Vehicle guidelines – CLICK HERE Read the Canadian Effectiveness of Heavy Truck Conspicuity Treatments – CLICK HERE

Sirens Report Accoustic characteristics for effective ambulance sirens Carl Q. Howard, Aaron J. Maddern and Elefterios P. Privopoulos School of Mechanical Engineering, The University of Adelaide, Adelaide, South Australia   This report published last year has a comprehensive comparison between an Australian siren mounted on a South Australian ambulance and   other types (including Rumblers) from around the world. A major confirmation in testing was the dramatic drop-off of 12db at 90 degrees to the forward axis. Subjectively this means the siren is less than half as loud out to the sides of the vehicle – this is a particularly important point when crossing intersections.
