Solution:

A priority intersection has a single lane one way traffic road crossing an undivided two lane two-way traffic road. The traffic stream speed on the single lane road is 20 kmph and speed on the two-lane road is 50 kmph. The perception-reaction time is 2.5s, coefficient of longitudinal friction is 0.38 and acceleration due to gravity is 9.81m/s. A clear sight triangle has to be ensured at this intersection. The minimum lengths of the sides of the sight triangle along the two-lane road and the single lane road, respectively will be
