INTERACTION BETWEEN CAUSALLY-IMPLICATED DRIVER MENTAL AND PHYSICAL CONDITIONS AND DRIVER ERRORS CAUSING TRAFFIC ACCIDENTS

The relationships between driver behaviors causing and immediately preceding an accident (Direct Causes), and accident causative impairments in drivers' predisposing mental and physical states (Indirect Causes) are analyzed from a representative sample of 420 traffic accidents. A Relative Involvement Factor (RIF) is developed to reflect the change in the likelihood of any accident-causing behavior being implicated given the existence of a causally relevant mental or physical impairment. The analysis indicates that causative conditions and states suppress certain direct causes while increasing the likelihood of others. Specific relationships are discussed.
