Abstract/Summary Understanding the drivers’ responses to critical events that the systems could detect, analyzing the drivers’ ability to perform corrective maneuvers that the systems could suggest, and uncovering the relationship between corrective maneuvers and crash severity appear key elements for designing effective crash avoidance systems. This study extends a line of research focusing on the determinants of engaging in crash avoidance maneuvers by considering that observable and unobservable factors relate to both the selection of corrective maneuvers and the severity outcome of the crash. Accordingly, this study proposes a joint multinomial-logit ordered-probit model for associating crash severity with the drivers’ propensity to engage in various corrective maneuvers in the case of the critical event of single-vehicle travelling. Five lateral and speed control maneuvers were considered: “braking”, “steering”, “braking & steering”, and “other maneuvers”, in addition to a “no action” option. Five severity outcome were considered: “property damage only”, “light injury”, “severe non-incapacitating injury”, “severe incapacitating injury” and “fatal injury”. Data were retrieved from the United States National Automotive Sampling System General Estimates System (GES) crash database for the years 2005-2009. Results show (i) the existence of unobserved factors relating crash avoidance maneuvers and crash severity, and (ii) the link between drivers’ attributes, risky driving behavior, road characteristics and environmental conditions, with the propensity to engage in crash avoidance maneuvers and experience crash severity outcomes.
