“…To the best of our knowledge there are no studies with real-time data that explore PTW accident risk, the literature review indicated that relevant studies have a more general scope and explore accident risk (Abdel-Aty and Pande, 2005; Abdel-Aty et Ahmed and Abdel-Aty, 2012;Xu et al, 2013a andHassan and Abdel-Aty, 2013;Abdel-Aty et al 2012;Yu and Abdel-Aty, 2013b), accident frequency (Yu and Abdel-Aty, 2013a;Yu et al, 2013) or accident severity (Christoforou et al, 2010;Golob et al, 2008;Abdel-Aty, 2014a and2014b;Xu et al, 2013b;Jung et al, 2010). It is also noted, that the vast majority of studies exploit data from freeways.…”
