The results showed that texting increased perceived mental workload and reduced the participants’ ability to discriminate hazards and reduced their likelihood of responding to a hazard. The purpose of this study was to explore how performing a texting task impacts a driver’s hazard perception ability while viewing real-world driving scenes using fSDT metrics.
