Differences in Injury Severities Between 2-Vehicle and 3-Vehicle Crashes

摘要

Objective and Methods: In traditional injury severity-related studies, 2-vehicle and 3-vehicle crashes are typically considered in a combinatory manner and thus the injury casual factors for these 2 crash types are implicitly assumed to be the same. This article attempts to investigate the potential discrepancy between 2- and 3-vehicle crash severities with the aid of a continuation ratio logit model with the property of partial proportional odds.
