(a) Assume that there are two interesting findings obtained from traffic crash analysis: An experienced driver was likely to induce a severe crash on highways even though there were adequate safety facilities. Majority of severe crashes occurring in the southwest Australia region were single- vehicle crashes rolling down from a hill. Give one (1) potential explanation of each finding. Then, propose one (1) solution for improving road safety based on each finding. (20 marks) (b) Assume that your proposed solutions stated in part (a) have been implemented. Discuss how you are going to evaluate the effectiveness of the solutions.
