Demographic changes show that the absolute number and portion of the population in Europe that can be categorized as older or very old will continue to grow over the next several years. One aim should be to keep them active and healthy for as long a time as possible. Exercise, for example cycling, plays an important role in this context but data shows that the elderly bicyclists are overrepresented in crashes when compared with their exposure to traffic. Senior cyclists' needs and preferences should be a base for developing a safe and joyful cycling environment. This project uses in-depth crash data analysis, questionnaires with senior cyclists, and questionnaires with experts to identify potential for improving elderly bicycling.Elderly bicyclists have a significantly higher risk than younger age groups. The consequences are significantly more severe for elderly bicyclists compared to other age groups and increase with vehicle speeds. Elderly bicyclists are significantly more involved in crashes when intending to turn left compared to other age groups. 22% of elderly in fatal crashes intend to turn left compared to 8% for adults and 14% for children.As expected, elderly bicyclists are significantly more often impaired by bad sight and/or bad hearing as well as being impaired from taking medication in crashes compared to other age groups. Elderly bicyclists are less often in a hurry (5%) in crashes compared to other age groups (11%). Elderly bicyclists obey traffic rules no more and no less than other age groups. In darkness (incl. dawn and dusk), non-elderly adult bicyclists are significantly more often involved in crashes (37%) than elderly (11%).The most stated safety-increasing measure according to the senior cyclists is construction of more cycle tracks. According to the expert questionnaire the most important preconditions were safety and a feeling of security when cycling, the existence of a network of roads for cycling including appropriate bike parking facilities and positive attitudes from users and non-users regarding travelling by bicycle. This is much in accordance with the opinions expressed by the senior cyclists.
