Figure 11
Two line graphs are presented side by side. The first graph, labeled Panel A, shows the left track longitudinal irregularity. The horizontal axis represents location in kilometers ranging from 283 to 283.4, and the vertical axis represents amplitude in millimeters ranging from -3 to 2. The line graph displays fluctuations in amplitude along the track. The second graph, labeled Panel B, illustrates carbody vertical acceleration. The horizontal axis also represents location in kilometers ranging from 283 to 283.4, and the vertical axis represents amplitude in g ranging from -0.04 to 0.04. This line graph shows variations in vertical acceleration of the carbody. Both graphs indicate irregularities and accelerations at specific locations along the track.Absolute correlation coefficient = 0.4. Source(s): Author's own work
