• Abstract:
  The effect of low visibility on both crash occurrence and severity is a major concern in the traffic safety ; field. It is known that crashes tend to be more severe in low visibility conditions than under normal clear ; conditions. Thus, there is a drastic need to evaluate low visibility countermeasures to improve driver ; safety and performance under reduced visibility conditions. ; For this reason, the research team investigated the human factors issues relevant to implementing a ; visibility system on Florida’s highways. Specifically, we designed driver simulator experiments to ; evaluate how drivers respond to low visibility warning strategies using an in-vehicle warning device. ; The repeated-measures analysis of variance (ANOVA) models were employed to analyze the impacts of ; low visibility and fog countermeasures. It was found that the fog warning systems can significantly ; improve safety. The systems can also reduce drivers’ throttle-release time and make the braking process ; more smooth. Meanwhile, age effects were observed during the braking process. Old drivers are prone ; to have harder braking than other drivers. ; Further research was conducted based on the drivers’ questionnaires. The results showed that drivers ; thought the head-up display had better effects than warning sounds. Also, drivers’ travel frequency and ; education levels have significant impacts on their behaviors. Those who drive fewer than five times ; every week or have higher educational attainment rates (a bachelor’s degree or higher) are more likely ; to have larger minimum time to collision.
