This report describes a brief literature study. The aims of this study are: (1) to determine what recent insights exist concerning the need for concrete adaptations to the infrastructure in response to the characteristics of elderly road users; and (2) to investigate what possibilities have been developed in that regard. The report is published within the context of a broader research project, namely: `The need for specific measures for the elderly', using the `sustainable-safe' concept. Recently published international literature relating to the elderly pedestrian seems to focus on `walking characteristics', generally in relation to intersections and traffic regulations. The clarity of traffic `rules' and road signs is given some attention. The viewing distance needed to stop in time and the perception requirements of road signs and markings are a specific subject of study where the older motorist is concerned. Various aspects relating to elderly cyclists are discussed primarily on the basis of the relevant Dutch literature. A final synopsis concludes that essential basic knowledge concerning the ageing process as a factor of human behaviour has become available. This knowledge will now need to be incorporated into new guidelines and other documentation. However, little knowledge is as yet available with respect to fitting age-related human behaviour into the infrastructure.
