• Abstract:
  The three studies included in the current report examine the transition from an infrastructure-based rural ; intersection crossing assist system to one located inside a vehicle. The primary goals of the first study, conducted in ; a simulator, were to examine the effect of potentially confounding factors, such as the drivers’ familiarity with the ; assist system and the impact of cognitive load on the drivers’ performance. Next, we examined the efficacy of ; several different designs of such system to determine the optimal interface design to be used for the in-vehicle ; system. Finally, the optimal design of the system was examined in the third study, as a field test. The results ; showed that the use of the system under cognitively demanding conditions did not result in any adverse ; consequences, which suggested that the processing of the system required minimal cognitive resources. ; Additionally, the results showed that the benefits of the assist system, such as reduced probability of accepting a ; critical gap were exhibited under the limited visibility conditions when the perceptual task of determining an ; appropriate crossing gap became overly demanding. The results from the field study showed that the use of the ; assist system resulted in improved intersection crossing performance exhibited in increased likelihood of making a ; complete stop at the stop sign and showed a strong trend toward a decreased probability of accepting critical gaps. ; Additionally, the impact of the in-vehicle CICAS-SSA was equivalent for older and younger drivers; that is, both ; age groups benefited from the use of the system.
