10-21. Consider an ideal single lane of road that carries 1,200 vehicles per hour uniformly spaced along the road and determine the following: a. The average center-to-center spacing of the vehicles for an average traf- fic speed of 40.0 km/h. b. The number of vehicles in a 1 km length of the lane when the average speed is 40.0 km/h. c. The sound level (dBA) 60.0 m from a 1 km length of this roadway with automobiles emitting 71 dBA at the edge of an 8.0 m-wide roadway. Assume that the autos travel at a speed of 40.0 km/h, that the sound radiates ideally from a hemisphere, and that contributions of less than 0.3 dBA may be ignored. Answers: a. Average center-to-center spacing = 33.3 m b. Number of vehicles in a 1 km length = 30 vehicles/km c. L₂ = 47.47 or 48 dBA
