Increasing motorcycles attention and search conspicuity by using Alternating-Blinking Lights System (ABLS)

► Increasing PTWs' conspicuity should involve both the riders and car drivers. ► Aids to PTWs conspicuity should be less susceptible to environmental influences. ► The ABLS increased PTWs' attention and search conspicuity. ► The ABLS was less susceptible to environmental changes and to expectancy levels. ► The ABLS dramatically increased PTWs detections in all driving environments.
