10-24. Determine the Lio noise level for the following highway traffic situation: Autos = 2,000 per hour Speed= 70 km/h Speed = 70 km/h Medium trucks = 200 per hour Heavy trucks = 0 Observer-roadway distance = 60.0 m Line-of-sight distance = 60.0 m Barrier position = 5.0 m = 1.0 m Break in line-of-sight distance Angle subtended = 160°

A driver noticed a road block while travelling at 40mph. He applied the brakes causing the car to decelerate uniformly at 6m/s2. The car stopped 12m from the road block. How far was the block when the driver saw it fırst assuming a perception time of 3s. Correct! O 92.40 m 92.4 26.67 m 53.67 m 27.0 m

Select the true items related to absorption capacity. Select only the four correct answers.      Practical absorption capacity is usually less than theoretical absorption capacity.     It is the minimum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour.     Absorption capacity depends on the vehicle arrival rate at the minor approach.     Practical absorption capacity is usually more than theoretical absorption capacity.     Absorption capacity does not depend on the flow of the mainstream traffic.      Absorption capacity depends on the flow of the mainstream traffic.      Absorption capacity does not depend on the vehicle arrival rate at the minor approach.     It is the maximum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour.
