Objectives:

To develop and test a small number of enhanced rear-lighting concepts that have the potential to reduce the number of rear-end collisions.

Methodology:

An expert panel consisting of twelve rear-lighting experts was assembled. The trade study was conducted electronically (email) via a series of three questionnaires. This process resulted in the recommendation of three rear-lighting configurations for further refinement.

Key Findings:

  • A set of enhanced rear-lighting concepts were developed after reviewing a variety of sources including literature, patent searches, and ideas provided by the expert panel, although the majority were a result of in-house concept generation.

  • Each concept was developed to include a description, a justification, implementation details, activation criteria, deactivation criteria, and a graphic representation. In all, eight concepts were developed,

Keywords:

Rear lighting, brake lights, rear-end crashes, rear signalling, focus groups, subject matter experts, trade study

Comments:

Unclear how the concepts were taken forward from this report. Presumably this was not the final output from the project.
