     international accident statistics indicate that elderly pedestrians make up an extremely vulnerable road-user group. past research has shown that older adults make many unsafe street-crossing decisions and adopt insufficient safety margins, especially when vehicles are approaching at high speed. apart from studies on road design and speed-limit countermeasures, there is surprisingly no road-safety research on behavior-based measures to improve older pedestrians’ safety. in this line, the present study was aimed at (i) assessing the effectiveness of a training program for older pedestrians that combined behavioral and educational interventions, and (ii) examining whether and to what extent age-related differences in street-crossing safety could be reduced after training older adults. twenty seniors were enrolled in a training program. before, immediately after, and six months after training, street-crossing behavior was assessed using a simulated street-crossing task. twenty younger participants performed the same simulated task to obtain a baseline measure. the results showed that the training produced significant short- and long-term benefits, due to a shifting of the decision criteria among the older participants towards more conservative judgments. when compared with the younger group, the older participants improved their behavior considerably so that significant differences in the mean safety-related indicators were no longer observed. however, the older participants’ ability to take the oncoming car's speed into account did not improve. even after training, and contrary to younger adults, older participants were found to make more and more unsafe decisions as the car's speed increased, putting them at a higher risk at high speeds. this finding may reflect age-related perceptual and cognitive difficulties that cannot be remedied by a behavioral or educational training method. the present findings underline that high speed is an important risk factor for elderly pedestrians that should be handled by effective speed reduction measures (i.e. speed ramps, road narrowing).
