Summary

This January 2018 report by the Virginia Tech Transportation Institute analyzes a large dataset of naturalistic driving data (3,593 drivers over 3 months) to determine the relationship between cell phone use and crash risk.

Main Findings:

- Visual-Manual Tasks Significantly Increase Crash Risk: Texting (OR 2.22), dialing (OR not statistically significant), browsing (OR not statistically significant), and reaching for or answering the phone (OR 1.83) all elevated crash risk compared to driving without any secondary tasks.

- Elevated Risk in Specific Traffic Conditions: The increased crash risk associated with visual-manual tasks was most pronounced in:
- Free-flow traffic (OR 2.46)
- Run-off-road crashes (OR 3.15)
- Rear-end crashes (OR 7.77)

- Handheld vs Hands-Free Conversations: There was a slight increase in crash risk during handheld conversations (OR 1.16), but the estimate lacked precision and wasn't statistically significant. Data on hands-free conversations was limited.

Conclusion:

The study reinforces previous findings that visual-manual interactions with cell phones while driving significantly elevate crash risk, particularly for tasks like texting. The lower estimated risks compared to prior studies may be attributed to the rigorous matching of crashes to similar driving conditions in this dataset.

Description

This study analyzes naturalistic driving data to determine the increased crash risk associated with cell phone use while driving, providing insights to aid in making safer driving decisions. It employs a case-crossover design to assess the immediate risks posed by diversions like cell phone usage. The research is supported by the AAA Foundation for Traffic Safety's mission to enhance driver safety through evidence-based understanding of behavior and performance.
