THC-positive cases (no other drugs or alcohol detected) showed an elevated relative risk compared to drug free drivers suggesting increased crash risk with recent cannabis use. When alcohol or other psychoactive drugs were also present this crash risk increased substantially. Recent use of cannabis therefore appears to be associated with an increased risk of a fatal car crash similar to a BAC o...

This paper introduces a novel methodology based on disaggregate analysis of two-car crash data to estimate the partial effects of mass, through the velocity change, on absolute driver injury risk in each of the vehicles involved in the crash when absolute injury risk is defined as the probability of injury when the vehicle is involved in a two-car crash. The novel aspect of the introduced metho...

Crash data from two UK resources were examined for differences between male and female passenger car drivers in collision circumstances and injury outcomes. The proportion of female car license holders is growing, women are more likely to be the driver in a collision and are more vulnerable to injury particularly neck strain. Women drive smaller, lighter cars compared to men and are more often ...

The following report contains information about a proposed technology by the authors, which consists of a device that sits inside of a vehicle and constantly monitors the car’s information. It can determine speed, g-force, and location coordinates. Using these data, the device can detect a car crash or pothole on the road. The data collected from the car is forwarded to a server to for more in-...

Networking of active and passive safety systems is the fundamental basis for comprehensive vehicle safety. Situation-relevant information relating to driver reactions, vehicle behavior and nearfield traffic environment are fed into a crash probability calculator, which continually assesses the current crash risk and intervenes when necessary with appropriate measures to avoid a crash and reduce...

child safety seat mishandle is still a concern. to prevent serious injuries and death from automotive accidents, correct use of car seats for small children is essential. failure to use a car seat properly can contribute to serious injury or death of a child. recent studies have shown that child safety seats can tolerate the impact of a minor crash without affecting their future performance. fa...

A 30-year-old woman crashed her car into a parked car after leaving work. She was restrained, and the car’s airbag did not deploy. When the paramedics arrived, she was confused and unable to answer questions appropriately. En route to the hospital, she had tonic-clonic seizure that lasted approximately 45 seconds. Upon arrival at the emergency department, she was unresponsive. Her vital signs w...

Buckling and certain contact situations cause scattering results of numerical crash simulation: For a BMW model differences between the position of a node in two simulation runs of up to 10 cm were observed, just as a result of round-off differences in the case of parallel computing. An engineer has to measure this scatter, to check whether important parts of the car show such indeterministic b...
