本文研究了从动力学描述导出二阶宏观交通模型的方法。特别是,我们恢复了著名的Aw-Rascle模型作为Enskog型动力学方程的流体动力学极限的车辆之间的微观二元相互作用的精确表征。与文献中的其他推导不同,我们的方法揭示了Aw Rascle模型背后的多尺度物理。这进一步使我们能够将其推广到一类新的二阶宏观模型符合Aw-Rascle一致性条件,即没有波应该比平均交通流量更快。
We study the derivation of second order macroscopic traffic models from kinetic descriptions. In particular, we recover the celebrated Aw–Rascle model as the hydrodynamic limit of an Enskog-type kinetic equation out of a precise characterisation of the microscopic binary interactions among the vehicles. Unlike other derivations available in the literature, our approach unveils the multiscale physics behind the Aw–Rascle model. This further allows us to generalise it to a new class of second order macroscopic models complying with the Aw–Rascle consistency condition, namely the fact that no wave should travel faster than the mean traffic flow.
