Using biological motion to enhance the conspicuity of roadway workers

▶ Perceiving other people is facilitated by biological motion (biomotion). ▶ Retroreflective biomotion markings enhance the conspicuity of pedestrians at night. ▶ We tested the value of adding biomotion markings to road worker vests at work sites. ▶ Road workers' conspicuity was rated highest in the full biomotion condition. ▶ Biomotion effectively enhances the conspicuity of road workers.
