The Influence of Contributory Factors on Driving Violations at Intersections: An Exploratory Analysis

Driving violation has been identified as one of the prominent contributing factors involved in crashes occurring at intersections. However, very little literature has studied the influence of contributory factors on driving violation. The goal of the present study was to analyze the effect of contributory factors on traffic sign and signals (TSS) violation, turning-yielding-signaling (TYS) violation, and speeding related (SR) violation at intersections, and the likelihood of each type of driving violation was predicted by using a multinomial logistic model. The findings of this study indicated that younger drivers (ages 15–24) had a propensity to commit SR violations, but older drivers (ages 65+) had the adverse situations. The likelihood of SR violations for males was higher than TYS violations, while contrary outcome was obtained during daylight. At traffic sign or signals controlled intersections, the odds of TSS violations and TYS violations were greater than SR violations, and similar outcomes were gained in four-way intersections or T-intersections. Drivers distracted cognitively were more likely to be in commission of TYS violations than SR violations, whereas it is opposite to passenger or in-vehicle related distractions. Inattention/distraction significantly affected the likelihood of each type of driving violation. Implications of the findings from current study are discussed
