“…To test this, we will perform traffic injury analysis for each traffic accident. We will apply the multinomial logit model, which is the most widely applied discrete-outcome modeling approach for accident-severity analysis (Zhang et al, 2000;Bédard et al, 2002;Al-Ghamdi, 2002;Islam and Mannering, 2006;Ulfarsson and Mannering, 2004;Kim et al, 2007, Carson andMannering, 2001;Shankhar and Mannering, 1996;Valent et al, 2002;Yau, 2004).
