To gain a better understanding of the problems that older drivers may be having on freeways, an analysis of freeway accidents of older drivers was conducted. This effort was conducted as part of the Federal Highway Administration (FHWA) research study "Investigation of Older Driver Freeway Needs and Capabilities" (FHWA-RD-95-194). This summary report describes the State data bases used, the analysis methods, and the results. In conclusion it is stated that the results from this analysis were combined with the results of a literature review, focus group discussions, and other tasks conducted in the FHWA study to develop a series of recommended research ideas to address the identified problems of older drivers on freeways. The problems identified in this accident analysis were related to lane-change and merge maneuvers of older drivers and their likelihood of being the driver at fault by failing to yield. Recommended research that has been identified as the result of this accident analysis includes: Identification of the ramp and mainline geometries and characteristics that contribute to freeway merge problems; Identification of geometric features and traffic control devices that can be used to minimize problems in transition areas; and Analysis of the behavior exhibited during lane-change and passing/overtaking maneuvers. |
