Accident studies indicate that the poor conspicuity of the cyclist is an important factor in accident causation. The visibility of various conspicuity aids was evaluated during daytime using a peripheral vision detection task. The aids were also tested on public roads by measuring the gaps left by vehicles overtaking a test cyclist. An ultrasonic ranging device was used for this purpose which automatically recorded passing distances. Visibility tests were carried out at night to find a conspicuous retro-reflective treatment for a cycling jacket. The results were used in making a jacket which was tested on public roads using the gap measuring technique. (Copyright (c) Crown Copyright 1984.)
