I came across this article from Trek on the ABC's of Awareness, which, of course, is meant to sell product. There is, however, lots of useful information that cyclists can use to improve their chances of being seen by the average motorist.
To summarize:
"A" stands for Always On, meaning that daytime running lights should be used.
"B" is for Biomotion, which has shown that the human perceptual system is hard wired to notice things that are alive and moving in ways that animals do. The most dynamic part of cycling in relation to biomotion would typically be the legs/feet/pedal, which is where always on or contrasting colors should be based for maximum visibility.
"C" represents Contrast, and basically represents that something that contrasts with the surrounding environment will tend to be noticed more than something that blends in. Basically, the idea being to go flouro during the day and reflective when dark.
Though I'm usually loathe to wear bright colours, some yellow shoes with reflective patches may be in my future.
