5-1 (60 Points) For this problem, you will use simulated data in FHWA TNM 2.5 to demonstrate how predicted highway noise varies by total traffic, traffic mix, vehicle speed, receiver distance, and the presence of a barrier. The problem will build on the TNM example presented in class. Your simulation will consider the following data: Distance from Roadway Centerline: 25, 50, 100, 250, 500 feet Traffic Volume: 500, 1000, 1500, 2000, 2500 vehicles per hour Traffic Mix: 0 percent, 10 percent, 20 percent, 30 percent trucks evenly divided between "Medium" and "Heavy" trucks. Remaining traffic will be "Autos" and there will be no buses/motorcycles. Traffic Speed: 40, 50, 60, 70 miles per hour Barrier Present: Yes or No
