A motorist is 50 ft from an intersection and sees a vehicle

A motorist is 50 ft from an intersection and sees a vehicle approaching from the right when it is 20 ft from the intersection. After removal of the foliage that has been blocking the sight line, it is now possible to see the same vehicle when it is 105 ft from the intersection. Average daily traffic volumes on the main roadway are 11,000 veh/day. Prior to the removal of obstructing foliage, the average number of crashes per year was 13.6. Determine the expected number of crashes per year after the foliage has been removed. Please show all your calculations (20%).
