Figure 6
The horizontal axis is labeled “Average travel time (in hours),” ranging from 40 to 80 in increments of 5 hours. The vertical axis is labeled “Frequency” and ranges from 0 to 90 in increments of 10 units. The distribution is bell-shaped but slightly skewed, with the highest frequency (nearly 60) occurring in the bin representing travel times between approximately 57 and 60 hours. A red dashed vertical line is prominently placed at the 56-hour mark, which, according to the legend, indicates the travel time “without wave variations.” The rest of the histogram bars, outlined in gray, represent the travel times “with wave variations.” Note: All numerical values are approximated.Average travel time considering wave variations.
