If I have a 45 mph secondary road with a stop sign, it appears to me that taking flow control into account is not really necessary. Are people finding meaningful differences by including flow control?
We would definitely recommend modeling the flow control device. Although you will not see a large difference between the A-weighted Sound Levels for Autos at 45 mph Cruise and the A-weighted Sound Levels for Autos accelerating in speeds of 0 to 45 mph Full Throttle (as seen in Figures 7 & 8 of the TNM Tech Manual), the vehicle emission spectra vary greatly over that range (as seen in Figures 17 – 20), and should be taken into account.
