The authors examined hazard perception (HP) abilities among elderly experienced and experienced drivers, with regard to the presence of pedestrians in residential areas. Two evaluation methods were used: (a) observation of traffic scene videos and pressing a button when a hazardous situation was identified, and (b) driving in a driving simulator. The results of the video observation method showed that elderly drivers had a longer response time for hazard detection. In addition, four of the eight pedestrian-related events were difficult for elderly drivers to perceive when compared to experienced drivers. Elderly drivers, shown to have limited useful field of view, may also be limited in their ability to detect hazards, particularly when located away from the center of the screen. Results from the simulator drive showed that elderly drivers drove about 20% slower than experienced drivers, possibly being aware of their deficiencies in detecting hazards and slower responses. Authorities should be aware of these limitations and increase elderly drivers' awareness to pedestrians by posting traffic signs or dedicated lane marks that inform them of potential upcoming hazards.
