Article Synopsis
- Sleepy drivers struggle to maintain lane position and may overcorrect steering, especially on slippery roads, leading to higher crash risks.
- A driving simulator study with 12 young men showed that sleepiness increased with driving time, particularly at night, and was exacerbated by slippery road conditions.
- While driving performance metrics showed some decline, the impact of road conditions on already tired drivers was not clearly reflected in performance outcomes.
Objective: This article provides a review of recent models of driver behavior in on-road collision situations.
Background: In efforts to improve traffic safety, computer simulation of accident situations holds promise as a valuable tool, for both academia and industry. However, to ensure the validity of simulations, models are needed that accurately capture near-crash driver behavior, as observed in real traffic or driving experiments.
Two experiments were carried out in a moving-base simulator, in which truck drivers of varying experience levels encountered a rear-end collision scenario on a low-friction road surface, with and without an electronic stability control (ESC) system. In the first experiment, the drivers experienced one instance of the rear-end scenario unexpectedly, and then several instances of a version of the scenario adapted for repeated collision avoidance. In the second experiment, the unexpected rear-end scenario concluded a stretch of driving otherwise unrelated to the study presented here.
