Naturalistic rapid deceleration data: Drivers aged 75 years and older

Area of Science:

• Gerontology
• Transportation Safety
• Human Factors Engineering

Background:

• Older drivers are a growing demographic, necessitating research into their driving safety.
• Rapid deceleration events (RDEs) serve as a surrogate measure for safety in naturalistic driving studies when crash data is insufficient.
• Understanding factors contributing to RDEs is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate potential predictors of older drivers' involvement in rapid deceleration events (RDEs).
• To analyze the relationship between vision, cognitive function, driving confidence, and RDEs in older drivers.
• To provide a dataset and methodology for future research on older driver safety.

Main Methods:

• Collected naturalistic driving data from 182 drivers aged 75-94 years over 52 weeks.
• Utilized in-vehicle monitoring devices to record accelerometer and GPS data.
• Defined RDEs as events with deceleration exceeding 750 milli-g (7.35 m/s²) within a 5-second duration.

Main Results:

• The dataset contains 473 RDEs from 182 older drivers.
• Detailed data processing, treatment, and quality control information is provided.
• The study provides a foundation for analyzing RDEs in older drivers.

Conclusions:

• The presented data and methods can inform future studies on older driver behavior and safety.
• This research aids in understanding the nuances of older drivers' involvement in critical driving events.
• The dataset serves as a valuable resource for advancing transportation safety research for aging populations.
