“…A number of environmental factors have also been linked to helmet use such as the road type, the weather and the time of day (Gkritza, 2009;Hung et al, 2006;Li et al, 2008;Nakahara et al, 2005;Skalkidou et al, 1999). Likewise, a number of helmet features have been shown to reduce the likelihood of using a helmet due to causing discomfort or influencing the rider's perception such as noisiness, temperature, poor ventilation, field of vision, functional and design errors (Bogerd, Rossi, & Bruhwiler, 2010;Buyan et al, 2006;Kennedy, Adetifa, Carley, Holt, & Walker, 2011;Mlynski, Kozlowski, & Zera, 2009;Orsi et al, 2012). Riders' beliefs and attitudes towards helmet use have also been shown to affect their helmet use practices with beliefs about injury prevention and safety being among the major facilitators of helmet use and beliefs about physical discomfort and limited vision and hearing, being major barriers of helmet use (Khan et al, 2008;Li et al, 2008;Ranney et al, 2010;Skalkidou et al, 1999).…”
