abstract="OBJECTIVE & Methods: In the traditional injury-severity related studies two-vehicle and three-vehicle crashes are typically considered in a combinatory manner and thus the injury casual factors for these two crash types are implicitly assumed to be the same. The paper attempts to investigate the potential discrepancy between two- and three-vehicle crash severities with the aid of continuation ratio logit model with the property of partial proportional odds. <br><br>RESULTS: The modeling results show that there are a number of significant differences between two- and three-vehicle crash injury severities in terms of the contributing factors, the magnitude of impact, and even the direction of effects. <br><br>CONCLUSIONS: The research illustrates that a series of environmental and crash factors (e.g., rear-end straight crashes, urban roadways, alcohol usage, and different driving cohorts) are statistically significant in interpreting the disparity of coefficients between two- and three-vehicle crash injury-severity models. It raises the awareness that the combined analysis of two- and three-vehicle crashes should be exercised with cautions, particularly when a safety research targets the less severe injury crashes.<p /> <p>Language: en</p>",
