The following table shows axle load spectra cluster assignments for each SPS TPF site. SPS TPF site ID is shown in the first column. Axle load spectra were developed for 25 class-axle combinations listed in the first row and analyzed using statistical clustering technique. Based on the results of the analysis, these load spectra were assigned to different statistical clusters. Each of the 25 class-axle combinations had 3 to 6 clusters representing different axle loading conditions. These clusters are identified in the cells by a number from 1 to 6. For each class-axle, the cluster that had the largest number of SPS TPF sites was called "typical." To identify which cluster is typical in the table, "typical" is included after the cluster number. In addition, when a cluster was formed by a single axle load spectrum, SPS TPF site ID was used to identify the cluster in the table instead of a number.
