A Comparative Analysis of Risk Associated with Eating, Drinking and Texting During Driving at Unsignalised Intersections

Presence of the distracting activities at unsignalized intersections can be highly dangerous, because both the decision-making and driving skills can be impaired while distracted. The present study conducted a critical analysis of risk associated with eating, drinking and texting during driving at unsignalized intersections. For this purpose, various gap opportunities were presented to the subject vehicle when it approached the unsignalized intersections in the simulated scenario. The risk evaluation was done in terms of reaction distance and accident probability for the approach and completion phase respectively by applying the Generalised Estimating Equations (GEE) method. In total, 89 drivers participated in the study. The results showed that the reaction distance was reduced by 5.5 m during the texting task, indicating impairment in the situation awareness capability. On the other hand, the risk during the completion phase was higher for the eating and drinking tasks while it was 76% lower for the texting task compared to baseline. It was observed that the drivers compensated during the texting task by reducing their speed in the approach zone and by selecting a larger gap in the major road traffic. The results indicate that eating and drinking tasks are not perceived to be dangerous by the drivers and hence they do not put any efforts in reducing the workload as they do for the texting task. Hence, the study suggests that the casual attitude for eating and drinking during driving can prove fatal for the driver as well as for other road users.
