Distribution of taxi vacant time of grids.(a) Kernel Density Estimation. (b) Empirical Cumulative Distribution Function. Note: some outliers (top 1%) were removed to increase the readability of the plot; the vertical dashed line in Figure 5(a) is the average of the grid taxi vacant time, and the horizontal dashed line in Figure 5(b) is the dividing line of the cumulative frequency at 90%.
