“…However, the current study found a significant age difference on crossing time 2 but not on exposure time. This suggests that safety margin may be underestimated and unsafe decisions overestimated when computed from the crossing time and that crossing behavior should be studied in an interactive road-crossing situation in order to collect relevant Confirming previous studies, our results yielded a strong effect of speed on crossing decisions and behavior, as shown previously in pedestrians Cavallo, 2007, 2009;Oxley et al, 2005;Simpson et al, 2003), but also in driver's left-turn gap acceptance (Alexander et al, 2002;Yan et al, 2007). However, the pattern of results revealed differences depending on age.…”

A c c e p t e d M a n u s c r i p t AbstractPast research has shown that road users accept shorter time gaps when the waiting time/number of vehicles they let pass before attempting to merge into the traffic increases.While elderly pedestrians are known to be an extremely vulnerable group of road users, very few studies dealt with the effect of environmental constraints and crossing complexity on this population's safety. The present study aimed at determining whether or not street-crossing decisions and behavior of younger and older pedestrians were differently affected by a traffic flow. In an interactive street-crossing task, we assessed whether mean time gap and crossing decisions depended on the position of the gap pedestrians selected into the traffic stream.Results revealed that irrespective of their age pedestrians accepted a smaller time gap when they chose the second interval of the traffic compared to the first one. Contrasting with previous hypotheses, this traffic-related behavior was not accompanied by an increase in the decisions risk. The findings also showed that the transition threshold from rejecting to accepting time gaps was shorter when the second interval was selected compared to the first one. This increment in task constraints might help younger and older pedestrians alike to perceive action possibilities more accurately and to be better attuned to traffic conditions by comparing gaps between each other. This opens an interesting perspective in the understanding and the training of the ability of elderly road users to remain accurate in their judgements.

“…In line with the findings of other studies by Vlahogianni and Golias (2012);Farah (2011);Forward (2010);Yan et al (2007); Kontogiannis et al (2002);Parker et al (1995), Yagil (1998), Deery (1999), Afukaar et al (2003); Iversen and Rundmo (2004), results of the study revealed that drivers' age has significant effect on the frequency of commission of traffic violations. From the study, younger drivers report a more often violation of traffic laws than old drivers.…”

“…In the case of back-to-lane maneuver, male drivers were observed to take longer time to return to their original lane than female drivers. In a gap acceptance study, Yan et al (2007) revealed that older drivers tend to accept larger gaps than younger drivers by using larger gaps to make left turns, keep higher car following distances and turn the steering wheel more slowly. Similarly, in terms of gender, male drivers accept smaller gaps than female drivers suggesting that older drivers and female drivers are more conservative.…”

This study investigated age and gender related differences in drivers' self-reported attitudes towards traffic violations and the gains or motivations influencing the violation of traffic laws in Kumasi. A total of 285 drivers were sampled for the study drawn from local bus terminals and taxi stations, work places, universities and other gatherings within the Kumasi Metropolis. Both self-completed questionnaires and interviews were used for the study. The results of the study showed that gender and age have significant influence on attitudes towards the commission of traffic violations though not by a large margin. The perceived gains associated with traffic violations also to a large extent influence driver attitude towards traffic violation in Kumasi with men being more motivated by the perceived gains to be derived from traffic violations than females. Neither significant nor great age differences were found regarding the extent to which perceived gains influenced the commission of traffic violations. Plausible explanations and implications for these findings to traffic safety campaigns as well as methodological issues are discussed. Suggestions for further research are also highlighted.

“…These situations are well documented in the literature. For instance, older drivers are over-represented in crashes occurring while turning off at intersections, where typically the older driver turns against oncoming traffic with right of way on the main road (Hakamies-Blomqvist, 1993;Zhang et al, 1998), gap acceptance while turning left at an intersection (Langford and Koppel, 2006;Yan et al, 2007) and response to signs, signals and road hazards (Bao and Boyle, 2008;Horswill et al, 2010). A detailed description of the driving scenario is mentioned in Cuenen et al (submitted).…”

This study investigates the relative performance of older drivers at the individual level, based on specific measures of functional and driving abilities. To do so, 55 participants aged 70 years and above completed tests of an assessment battery of psychological and physical aspects as well as knowledge of road signs; moreover, they took a driving simulator test in which specific driving situations that are known to cause difficulties for older drivers were included. To evaluate the overall performance of each driver, all the above information was combined by using the concept of composite indicators, and the technique of data envelopment analysis, which is an optimization model for measuring the relative performance of a set of units, or drivers in this study, was employed. The model output distinguishes the best-performers from those underperforming drivers, and helps in guiding future development of training interventions tailored to each individual by specifically targeting those functions that are (mostly) impaired.
