• 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.
