The average speed of vehicles on a road with a downgrade of 4% is 90 kph. A traffic study was conducted to improve the braking distance (reduce the braking distance) due to a high risk of accident occurrence on this road during the night. a. If the existing braking distance is 120 m, determine what would be the recommended speed limit based on a reduction in braking distance of 20%. Use Table 1 for values of coefficient of friction f according to design speeds. You may interpolate in between values. Answer: v = 80.10 kph b. If the grade is to be reduced to achieve this reduction in braking distance, what would the new grade of the road be? Answer: G = +3.48% Table 1.
