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

行人和骑自行车的人死亡是一个主要的道路安全问题，占道路死亡人数的三分之一，估计每年的成本为25亿美元。司机对行人和骑自行车的人识别较晚是造成这些碰撞的主要原因。我们已经证明，创新的能见度设计，包括在活动接头上巧妙地放置反光标志，可以大大提高能见度，从而提高这些易受伤害的道路使用者的安全。我们将扩展这项研究，以纳入对这些可见性解决方案在真实世界环境中的评估，并通过教育和政策变化鼓励在现实世界中广泛使用这些设计。

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.
