Using 'biological motion' to enhance the nighttime safety of road workers, cyclists, and pedestrians

Pedestrian and cyclist fatalities are a major road safety problem, accounting for a third of road fatalities at an estimated cost of $2.5 billion/year. Late recognition of pedestrians and cyclist by drivers is the main reason for these collisions. We have shown that innovative visibility designs which involve strategic placement of reflective markers on the moveable joints can greatly enhance visibility and hence safety of these vulnerable road users. We will extend this research to incorporate evaluation of these visibility solutions in real-world environments and encourage the widespread use of these designs in the real-world through education and policy change.
