Young drivers’ perception of adult and child pedestrians in potential street-crossing situations

Abstract

Despite overall improvements in road traffic safety, pedestrian accidents continue to be a serious public health problem. Due to lack of experience, limited cognitive and motoric skills, and smaller size, children have a higher injury risk as pedestrians than adults. To what extent drivers adjust their driving behaviour to children's higher vulnerability is largely unknown. To determine whether young male drivers' behaviour and scanning pattern differs when approaching a child and an adult pedestrian in a potential street-crossing situation, sixty-five young (18-24) male drivers' speed, lateral position and eye movements were recorded in a driving simulator. Results showed that fewer drivers responded by slowing down and that drivers had a higher driving speed when approaching a child pedestrian, although the time of the first fixation on both types of pedestrians was the same. However, drivers drove farther away from a child than an adult pedestrian. Additionally, fewer drivers who did not slow down fixated on the speedometer while approaching the child pedestrian. The results show that young drivers behave differently when approaching a child and an adult pedestrian, though not in a way that appropriately accounts for the limitations of a child pedestrian. A better understanding of how drivers respond to different types of pedestrians and why could contribute to the development of pedestrian detection and emergency braking systems.

Predictive Probability Models of Road Traffic Human Deaths with Demographic Factors in Ghana

“…On the part of human factors, Wu and Xu [21] and Abele et al [22] highlighted that driver behaviors such as speeding, drunk-driving, fatigue, safety measures adopted, and risktaking behaviors are the most influential causes of traffic-related causalities. Febres et al [23] blamed young drivers for risky driving behaviors.…”

Driving Risk Analysis Based on Driving Experience at Hook-Turn Intersection Using the Emerging Virtual Reality Technology

“…Obeid et al [25] used a driving simulator to analyze driver-pedestrian interaction from the driver's perspective and concluded that a driver's aggression is affected by approach velocity, curbside parking, crosswalks, and the number of pedestrians crossing the street. � Abele et al [26] compared young drivers' interaction behavior with child and adult pedestrians. ey found that curb extension was the most efficient safety measure that led to the most appropriate driving speed at pedestrian crossings [27].…”

Defining interactions: a conceptual framework for understanding interactive behaviour in human and automated road traffic

“…An important aspect here is that road users' decisions on what interactive behaviours to adopt are clearly affected by the specifics of the traffic environment in question, as interpreted against the backdrop of the previously discussed shared reference frame, or common ground, of the interacting road users. Also individual factors such as gender and age matter in this respect (Plumert, Kearney, and Cremer 2007;Ābele, Haustein, and Møller 2018;Lobjois, Benguigui, and Cavallo 2013), as do factors related to human attention or capacity limitations, and secondary tasks and distractions (Janouch et al 2018;Thompson et al 2013;Ljung Aust, Fagerlind, and Sagberg 2012;Choudhary and Velaga 2017).…”
