The computer program LS-DYNA3D was used to simulate the behavior of a specific, though representative, heavy truck cab-over tractor-trailer vehicle during a full 180° rollover event. These simulations provide a key component in the development of a physical testing procedure for evaluating structural integrity and occupant crash protection system designs in heavy trucks.
The topic of Connected Vehicles and Autonomous Vehicles is not new, yet advances in computing power, wireless capabilities, and soft ware development are taking implementation predictions from the not-too-distance future and placing them in the here and now. Emerging vehicle technologies foreshadow a world in which sensors and soft ware will replace humans in the driver's seat.
One of the unfortunate problems with non-news-oriented magazines is the juxtaposition of their readers' limited long-term memories coupled with the publishers' reluctance to repeat themes (much less whole articles) that are not linked to stories that reflect continuing news or problems.
Airbags in modern automobiles have been around for many years and their record in improving occupant safety in crashes is generally well accepted. However, many questions still arise regarding their deployment and performance in crashes.
Each year, there are approximately 1,500 incidents and 600 deaths occur involving vehicles that have gone off the road and plummeted into the water. Therefore, the public needs to plan for these types of emergencies by (A) rehearsing the steps necessary for a successful self-rescue from a vehicle in the water, and (B) having the rescue/escape tools readily available for use during this type of emergency situation.
Many of our fundamental and commonly-held beliefs are invalid because they were derived, often haphazardly, from a blur of intuition, superstition, history, tradition and circumstance rarely subjected to scientific scrutiny. Before the inventions of artificial light and mechanical clocks, being awake during daylight and asleep during darkness were survival necessities - lest one be devoured by predators or stumble into a pit.
In my review of more than 80 public transportation-related accidents and law suits, one almost universal theme has been the absence of any log review. This failure has generally combined with another common theme: A vehicle running behind schedule. The relationship between these two themes is easy to both understand and demonstrate - as is the acknowledgement that they constitute a genuine safety problem. But in a courtroom, the fact that system management failed to notice the vehicle running late - and worse, failed to even look for it - translates into a liability problem as well.
