We perform statistical analysis of the single-vehicle data measured on the Dutch freeway A9 and discussed in [2]. Using tools originating from the Random Matrix Theory we show that the significant changes in the statistics of the traffic data can be explained applying equilibrium statistical physics of interacting particles.

An important assumption in the analysis of multienvironment cultivar trials is homogeneity of error and genotype 3 environment interaction variances. When variances are heterogeneous, the best estimators of performance are obtained by weighting inversely to variance components. However, because variances are almost never known and must be estimated, the additional error introduced into the mode...
