“…As far as we know, however, there are no assessment studies that show the beneficial effects on the increased risk specific to collisions between pedestrians and powered two wheelers. Concerning the even greater increased risk among moped users of hitting a pedestrian compared with the other categories of powered two-wheelers, it is probable that this increased risk comes at least in part from the various risk factors already well identified in the scientific literature, such as young age (Kopjar, 1999;Aare and Holst, 2003;Lardelli-Claret et al, 2005;Moskal, Martin and Laumon, 2012), inexperience (Yannis, Golias and Papadimitriou, 2005;SWOV, 2006;Blackman and Haworth, 2013), a greater tendency to intentionally break certain traffic rules (Van Elslande and Marechal, 2008;Steg and Van Brussel, 2009;Wang et al, 2012) and, more generally, to take risks (ECMT, 2000;Yannis, Golias and Papadimitriou, 2005;Brandau et al, 2011). For example, based on 94 in-depth inquiries into accident cases involving young moped drivers, Van Elslande and Marechal (2008) found that intentional violation of a safety rule occurs in nearly one in five cases whereas it is only seen in 5% of all cases in the general population.…”
