Figure 4
A scatter plot with dozens of blue data points representing the relationship between predicted and observed primary delays. The x-axis represents observed delay in minutes, ranging from 0 to 60. The y-axis represents predicted delay in minutes, also ranging from 0 to 60. A red dashed line labeled 'Ideal prediction' runs diagonally from the bottom left to the top right, indicating a perfect correlation. The data points generally follow this line but with some variation, showing a positive correlation between predicted and observed delays. All values are approximated.Predicted vs observed primary delays. Source: Authors’ own work
