Transient and steady state scaling exponents.
Colormap of the (a) transient and (b) steady state values of the scaling exponent and as a function of car density and the mean randomization probability . Dashed lines show the approximate super diffusion () and normal diffusion () boundaries. Region I (a) is always superdiffusive () indicating a good region for traffic. Region II generally starts with a superdiffusive transient behavior () then approach . Lastly, Region III is subdiffusive. The scaling exponent is independent of .
