APPENDIX I: COMPARISON OF MODELED AND MEASURED RESULTS (ADJUSTED FOR REFERENCE MICROPHONE)

In these figures, the colored circles represent individual 5-minute model computations (color coding is given in the legend); the blue dashed line shows the first-order linear regression between the two datasets; the blue dotted lines indicate the 95-percent prediction interval for any new computations; and the solid black line indicates where all results would fall if both models gave the same predictions for all analyses. Note that in the upper left-hand corner of the graph several statistical parameters are presented: the number of samples, the coefficient of determination (r2), the root mean squared error (RMSE), the regression slope and intercept, the regression equation, and the average difference. These statistics are also repeated in the tables that follow. In the lower right-hand corner, a metadata summary is provided covering the number of sites, the presence of a barrier, receiver distances and heights, number of roadway lanes, pavement type, and temperature and wind conditions included in the analysis. Each site is presented in a different color in order to help highlight any potential grouping of the data.

In general, the larger the sample size, the higher the confidence for the computation of all parameters. In this report, the maximum number of modeled samples is 5987. When sub-sets are examined, the number of samples will be smaller. The r2 provides a measure of correlation. The RMSE provides a measure of absolute variation between the two predictions and represents the sample standard deviation. A slope (m) of one indicates that for every 1-dB change in one model's prediction there will be an identical 1-dB change in the other model's prediction. If the slope is less than one, then the model on the y-axis tends to change predictions slower than the model on the x-axis and vice versa. If the intercept (b) is zero and the slope is one, then there is perfect agreement between the two datasets. If the intercept is negative, then the model on the y-axis predicts lower levels than the model on the x-axis for low levels and vice versa; however, the average difference provides a measure of the overall bias between the two datasets.
