Test road experiment on imminent warning rear lighting and signaling.

Objective: This paper describes an experiment directed toward refinement and initial field testing of two potential countermeasures for the problem of rear-end (RE) crashes. The countermeasures consist of "imminent warning" signals intended to direct the following driver's visual glance to the lead vehicle as it brakes rapidly to a stop and for a short time thereafter.

Background: RE crashes are the most frequently occurring type of light vehicle crash, making up at least 25% of all crashes.

A descriptive analysis of light vehicle-heavy vehicle interactions using in situ driving data.

Two recently completed on-road in situ (naturalistic) data collection efforts provided a large data set in which to conduct an examination of crashes, near-crashes, and crash-relevant conflicts (referred to as critical incidents throughout this paper) that occurred between light vehicles (LV) and heavy vehicles (HV). Video and non-video data collected during the two studies were used to characterize critical incidents that were recorded between LV and HV drivers. Across both studies, 210 LV-HV critical incidents were recorded.

An on-road study to investigate fatigue in local/short haul trucking.
