Serious and Fatal Injury Risk in Road Departure Crashes with Guardrail
Guardrails are a key safety feature of modern roadways. Collisions with many roadside hazards, e.g. trees, poles and culverts, can be dangerous and guardrail prevents many crashes with such hazards. However, using guardrail safely and effectively is a challenging problem in itself. This research …

Injury Risk of Road Departure Crashes using Modeling and Reconstruction Methods
… 40,000 traffic-related fatalities. Common roadside objects such as trees, poles, guardrails, embankments, culverts, and fences result account for roughly 46% of these fatalities. Efforts to reduce to injury risk and risk exposure in these crashes have been hampered by the difficulty in …

Fleetwide Models of Lane Departure Warning and Prevention Systems in the United States
Road departure crashes are among the deadliest crash modes in the U.S. each year. In response, automakers have been developing lane departure active safety systems to alert drivers to impending departures. These lane departure warning (LDW) and lane departure prevention (LDP) systems have great …

Radar Characteristics Study for the Development of Surrogate Roadside Objects
… One of the biggest threat of driving safety is road departure. Many vehicle active safety technologies have been developed to warn and mitigate road departure in recent years. In order to evaluate the performance of road departure warning and mitigation technologies, the standard testing …

Residual Crashes and Injured Occupants with Lane Departure Prevention Systems
… individuals are fatally injured in crashes on US roads [1]. These fatalities occur across many types of crash scenarios, each with its own causation factors. One way to prioritize research on a preventive technology is to compare the number of occupant fatalities relative to the total number of …

Applications of Event Data Recorder Derived Crash Severity Metrics to Injury Prevention
… annually due to crashes on United States roads [1], [2]. Typically, road departure crashes account for less than 10% of all annual crash occupants yet comprise nearly one third of all crash fatalities in the US [3]. In the year 2020, road departure crashes accounted for 50% of crash …

Determination of Sensors Characteristics of Curb and Development of Surrogate Curb for the Evaluation of Vehicle Active Safety Systems
… of the critical models is the model adopting the Road Departure Assisting Techniques (RDAT). These techniques are primarily the standards for alleviating the risk of roadside fatalities. The different models developed or proposed for RDAT falls under “The Road Departure Mitigation System” (RDMS). …

Modeling, analysis, and measurement of passenger vehicle stability
… of rollovers occur when a vehicle departs the roadway and encounters sloped and rough terrain at high speed. This thesis investigates the stability limits imposed by off-road terrain conditions and techniques for measuring vehicle stability in the presence of off-road terrain factors. An …

The Effectiveness of Graduated Driver Licensing in the United States
… also have higher rates of control loss and road departure crashes when compared to adults. Finally, it was found changes in the number teen driver crashes and fatalities are associated with similar changes in travel exposure. Teen crashes and fatalities have dropped with the implementation …

Pedal Misapplication: Past, Present, and Future
… These PM crashes were typically rear-end or road departure crashes in moderate- to low-speed commercial or residential areas. Female drivers and elderly drivers were more often involved in these PM crashes, which generally featured slightly lower injury severities and often involved …

A Dataset of Vehicle and Pedestrian Trajectories from Normal Driving and Crash Events in One Year of Virginia Traffic Camera Data
… pedestrian crashes were identified from PARs. Road departure and rear-end crashes occurred in similar proportions to national databases, but intersection crashes were underrepresented and severe and rollover cases were overrepresented. Among these crashes, 32% of single-vehicle crashes and 50% …
