Self-organizing traffic lights (SOTL) methodology is highly popular and is the subject of much discussion (e.g., [1–7]). Zhung et al. [1] (based on constructions presented in [2]) claim that by using SOTL “overall better performance and higher capacity can be achieved” in comparison to the systems normally used by traffic authorities. “The idealized control scheme SOTL, which is designed to uni...

Detrended Fluctuation Analysis (DFA) is widely used to assess the presence of long-range temporal correlations in time series. Signals with long-range temporal correlations are typically defined as having a power law decay in their autocorrelation function. The output of DFA is an exponent, which is the slope obtained by linear regression of a log-log fluctuation plot against window size. Howev...
