Accelerometer-based safety surrogate measures
Submission Date: 2019
A literature review was conducted to identify telematics-detected accelerometer-based safety surrogate measures (SSMs) used in peer-reviewed, published road safety studies. Five types of SSMs were identified, including: longitudinal deceleration, longitudinal acceleration, lateral acceleration, jerk and yaw. Findings for each measure were categorised into those associated with crashes and near-crashes (CNCs) and/or incidents, and those used as SSMs. This presentation will describe these SSMs; discuss the aims, methodology and results of the literature review; and make recommendations for potential SSM definitions and thresholds, and methods for data validation and reduction for use in future on-road driving studies.
