Title:

Mobile Phone Use During Driving: Effects on Speed Reduction and Effectiveness of Compensatory Behavior

Accession Number:

Record Type:

Component

Abstract:

This study analyzed and modeled the effects of conversation and texting (each with two difficulty levels) on driving performance of Indian drivers in terms of their mean speed and accident avoiding abilities; and further explored the relationship between the speed reduction strategy of the drivers and their corresponding accident frequency. 100 drivers of three different age groups (young, mid-age and old-age) participated in the simulator study. Two sudden events of Indian context: unexpected crossing of pedestrians and joining of parked vehicles from road side, were simulated for estimating the accident probabilities. A multiple linear regression model for mean speed and a binary logistic regression model for accident probability were developed. Results of the models showed that in the presence of conversation and texting, drivers significantly compensated the increased workload by reducing their mean speed by 2.62 m/s and 5.29 m/s respectively. Logistic models for accident probabilities showed that the accident probabilities increased by 3 times and 4 times respectively when the drivers were conversing or texting on a phone during driving. Further, the relationship between the speed reduction patterns and their corresponding accident probabilities showed that all drivers compensate differently; but, among all the drivers, only few drivers, who compensated by reducing the speed by 30% or more, were able to fully offset the increased accident risk associated with phone use.
