ABSTRACT
In this topic we get to learn about the various safety precisions for the numerous vehicles
and the techniques to avoid any undesirable event. We also learn the effects of the technology on
human lives and why it is necessary to have it, is also discussed further. And it is also required
that the use of various alternate devices should also be observed. This report gives knowledge
about all the points mentioned above and informs us that it is important to implement all this to
save life of vehicle and to maintain human security.
For more than three decades accident reconstruction methods have been successfully
used in investigating real-world crashes and determining causes of crashes and injuries. It is of
value when the data lead to deployment of crash prevention and crash protection
countermeasures. The usefulness of this approach in predicting future safety needs based on past
historical data is becoming less useful because of the changing pace at which new technologies
are coming in to the vehicle fleet.
As the focus on countermeasures shift from crash protection to integrated safety, the need
for crash causation data and its interpretation are becoming more critical. This session invites
papers aimed at a discussion of future data collection and analysis methods such as naturalistic
driving data on vehicles’ performance, analytical methods for estimating potential benefits of
safety technologies, evaluation methods of video data, and universal descriptions of crash causal
factors and resulting crash types. These methods are likely to serve as the foundation for detailed
analyses of real-world crash data in developing countermeasures for safety enhancement and
determining potential benefits of safety enhancement features in the future.
