Green Blog posted a article in Cars & TransportationResults from a study done by a research group at the Skövde University in Sweden might surprise cyclists. Their research project, named Urbanist 2, have looked at how well reflexes helps motorists’ spot cyclists in the dark. Their conclusion is that it is dangerous to rely on the bright, and among cyclists, popular reflective vests. “What we have seen in our research is such that the reflective vest provides a false sense of security at night, when it in no way helps the motorist to interpret the rider's movement information,” said Paul Hemeren, PhD in Cognitive Science at the University of Skövde. Instead, their findings show, it’s more important where on your body those reflexes are located. The best placements are on the head, arms, feet, and other body parts that are moving when you’re cycling. “If you place a reflective stripe on the back of the helmet, which continues in a vertical line down the back, you create a line that breaks when the rider turns his or hers head,” Hemeren said. “This shows [for the motorist] that it’s a high probability that the cyclist will turn. And if reflexes are also placed on other body joints you will reach an even better result.” If the reflexes are placed like this, it reinforces a riders unconscious patterns of movement and in turn makes it easier for the motorist to make an accurate assessment of the cyclist’s intentions – in up to 97 percent of the cases. Without it, the study finds that the motorists could only make a correct assessment in little over 70 percent of the cases. Obviously one shouldn't draw too many conclusions from only one study, but apparently, those reflective safety vests used by many cyclists might not do much to protect the wearer – at least if the wearer is on a bike.
