| Abstract | This report describes a turn-key system that was developed and implemented to collect the vehicle source height database for incorporation into the new Traffic Noise Model (TNM). A total of 2500 individual vehicle pass-bys were measured with this system at 16 different sites around Florida and these data are presented in the form of averaged curves for each vehicle type. The dependence of source height on speed, pavement type, road grade and acceleration state is also shown for 10 different types of vehicles. The effect of these roadway conditions on the vehicle source heights is small compared to the typical variation in the whole data set. A recommendation is therefore made that the overall average of the data for each vehicle type be used in the TNM model and that variations with speed, pavement, grade and acceleration can be neglected. |
