    • Often the terms "Euler equation" and "Navier-Stokes equation" denote the respective velocity equation only. Since it is easier to name the whole set of connected equations (containing the respective density equation, velocity equation, and variance equation) by one single term, the notation of Ref. [55] has been applied here.

    • note
    • Phillips [3] fits his traffic data not to a Gaussian distribution but to a more complicated one which he derived from his gas-kinetic model. However, Phillips figures clearly show that, in the region of stable traffic, the asymmetric distribution function favored by him does not fit the data as well as a Gaussian distribution would.

    • This derivation is not really consistent since the relaxation time tau; ≈ 10 s in (8) is not of the order of magnitude which τ has in the follow-the-leader models where it has the meaning of a reaction time (≈ 1.3 s [41,23])

    • Payne's simulation model FREFLO, in contrast to his macroscopic model (1) and (8), predicts unstable traffic flow above a critical density that depends on the spatial discretization Δτ [45]

    • 0(r, t) Interestingly enough, the adaptation term does not bring about modifications of the density equation, the velocity equation, the variance equation, or the covariance equation derived later on. Therefore it was not included in the main discussion.
