Research Question: Which factors influence road traffic fatalities for automobil

Research Question: Which factors influence road traffic fatalities for automobile drivers? Is it because people are driving more? Or is it because of people’s lack of awareness on their own safety (i.e.wearing seat belt)? (Examine at a state level).
I have done with all the data running and examine; however, I need the literature part to be done. Therefore, please focus on the writing part for this paper.
I have uploaded the instruction, the partial part that I have done for the paper and also the data set. Please follow the instruction carefully and finish the writing part. Thank you and let me know if there are any questions.
