STATISTICAL COMPARISON OF STAMINA 1.0 AND STAMINA 2.0/OPTIMA FOR A TYPICAL BARRIER

The FHWA has produced several computer versions of its highway noise-prediction model, including STAMINA 1.0 and STAMINA 2.0/OPTIMA. These two versions are nearly indentical mathematically, but STAMINA 2.0/OPTIMA has several new features designed to enhance accuracy and, more importantly, to lead to better barrier designs. The results of a simultaneous application of STAMINA 1.0 and STAMINA 2.0/OPTIMA for the same barrier, which is located on I-65 immediately north of the proposed I-65/I-440 interchange in Nashville, are reported. Basic statistics are used to evaluate differences between program output. Also, the nonoptimized final barrier design for STAMINA 1.0 is compared with the optimized STAMINA 2.0/OPTIMA barrier design in terms of cost. Although all the results of an in-depth research endeavor are not reported in this paper, two significant conclusions are demonstrated for theis application. First, STAMINA 1.0 and STAMINA 2.0 produced basically equivalent results, which is to be expected. Second, the optimization process produced a significant reduction is expected barrier costs based on cost data contained in OPTIMA.
