This study is being performed with two main goals in mind. The first is to describe the characteristics of fatal crashes. Specifically perform a descriptive epidemiology study to understand how likely a fatal crash is during nighttime versus daytime driving. The data for the descriptive study were analyzed in terms of type of person, time of day, and weather. The study demonstrated that there is a higher fatality rate during nighttime for all different types of persons involved in a fatal crash. Specifically, the fatality rate for pedestrians, during nighttime, is twice the fatality rate during daytime. The second goal is to evaluate new technologies to enhance night vision. The empirical research aims to identify how new technologies are able to enhance night vision. This research provides empirical data on 12 vision enhancement systems taking also into consideration factors such as driver age, type of objects on the roadway (i.e., static and dynamic objects), and weather. The vision enhancement systems will be comprised of five technologies: (1) halogen headlamps, (2) high intensity discharge headlamps; (3) three levels of UV-A (low, middle, and high), (4) infrared thermal imaging system, and (5) high output halogen. |
