Provide a detailed report on the current statistics of automotive accident rates, injuries, and fatalities in the US and worldwide. Additionally focus on statistics involving distraction related to cell phone use and whether we are solving the problem or the problem is getting worse.

Answer preview


Automotive accidents have become a major problem in the world because they are experienced everywhere. In the United States, the automotive accidents rate is 6 million accidents per year (Puthanpura, Khalifa, Chan, & Barham, 2018). This means that approximately 16,436 accidents happen each day in the United States. In those accidents, about 3 million people suffer from serious injuries every year, where some of them experience permanent disability. According to Thompson (2020), around 37,000 people are killed by road accidents every year in the United States. Reports have also shown that the global death rate of automotive accidents is 1.35 million deaths per year. Apart from the recorded death rate, 20 million people suffer injuries from road accidents per year, leaving many families poor because of overwhelming medical bills.(345 words)


Vigilance is the ability to be observant of things that can cause danger. There are various factors that affect vigilance performance. The first factor is the sensory modality, which represents the mode used to receive signals. When an observer receives both visual and audio signals, there is high vigilance performance than when a single sensory mode is used. The second factor is signal salience, which is the ability of the signal to be sensed. That is, the higher the intensity of critical signals, the lesser the number of uncultured signals. The third factor is the stimulus uncertainty. This occurs when it is hard to know the exact time the critical signal will occur or where on display, the signal will occur (See, 2014). (241 words)


During the research, either the experimental or correlational method can be used. However, the two methods are different in terms of their implementation. In an experimental method, a researcher makes some changes and figures out the effect of those changes. This means that the experimental method is based on the relationship between a cause and its consequences. For example, a poor sleeping style causes back pain. On the other hand, the correlational method is used to find out the relationship between two or more variables. Unlike the experimental method, there is no causal relationship between the variables. Correlation can be represented as either positive, negative, or no correlation (Campbell, 2012).(239 words)
