Analysis of Risk Factors in Fatal Intersection Crashes Involving Older Drivers in the Midwestern Region
Publication: International Conference on Transportation and Development 2021
ABSTRACT
Older drivers aged 65 years and older are more vulnerable to fatal crashes due to cognitive impairments and frailty. The objective of this study was to determine factors associated with intersection-related crashes involving older drivers in the Midwestern states. A five-year fatal crash data set from 2014 to 2018, from the Fatality Analysis Reporting System (FARS), was utilized. The logistic stepwise selection procedure was applied to identify statistically significant predictor variables. The model identified eight statistically significant predictor variables out of thirty. The predictors that increase older-driver single-vehicle fatal crashes at the intersections are if trafficway type is two-way undivided, if the land use is urban, if the intersection is with control, if the time is between 8 p.m. and 8 a.m., if the age is 75+ years old, if the posted speed limit is lower than 55 mph, if the pre-crash event is speeding, and if the most harmful event is other than rollover or hitting a tree.
