Comparing the Characteristics of the Target and Bullet Vehicle for Injury Severity in Two Vehicle Crashes
EXTENDED ABSTRACT: This paper undertakes an in-depth analyses of the driver reaction and crash severity of the target and bullet vehicles in two vehicle crashes. Previous driver reaction and crash predictive modelling are reviewed. Statistical analysis (Cross tabulation, Chi-Square test and T- test) are conducted to identify the relationship between injury severity human; vehicle; road geometric; environmental; and crash or dynamic factors for the target and bullet vehicle. The 2009 – 2014 National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) is used in the analysis. The results indicates that struck and striking drivers are differentiated in terms of the human factors, age, gender, and delta V. For instance, high percentage of severe or fatalities is related to:
a) male drivers over female (Figure 1).
b) struck over striking vehicles at delta V more than 20 km/hr (Figure 3).
c) risky segments; non interchange and non-junction or intersection. Right angle crashes are the most risky for driver among other crashes types.
Future work could investigated the differences between single and two vehicle crashes related to crash severity and driver avoidance manoeuvers.
