Rear-end crashes account for more than 29 percent of all crashes; these types of crashes often result from a failure to respond (or delays in responding) to stopped or decelerating lead vehicles (NHTSA, 2007). The work described here is part of a larger program of research intended to develop and evaluate rear signaling applications designed to reduce the frequency and severity of rear-end crashes by redirecting drivers’ visual attention to the forward roadway (for cases involving distracted drivers), and/or increasing the saliency or meaningfulness of the brake signal (for attentive drivers). This study quantified the attention-getting capability of a set of candidate rear brake lighting configurations, including proposed approaches from automotive companies. This study was conducted to provide data for use in a simulation model to assess the effectiveness and safety benefits of enhanced rear brake light countermeasures. This Vehicle Safety Research Note is a summary of the technical research report, Evaluation of Enhanced Brake Lights Using Surrogate Safety Metrics. Task 2 & 3 Report: Development of a Rear Signaling Model and Work Plan for Large Scale Field Evaluation. (DOT HS 811 329).
