摘要:

我们证明了建模多类车辆交通的非局部守恒律一般系统解的全局存在性、唯一性和 $\L1$ 稳定性。每类遵循自身的速度规律,并对其他类的速度产生特定影响。此外,允许速度规律对空间和时间的一般显式依赖。解被证明在合适的范数下连续依赖于方程中出现的所有项以及初始数据。数值模拟展示了非局部项的相关性与影响。

英文摘要:

We prove global existence, uniqueness and $\L1$ stability of solutions to general systems of nonlocal conservation laws modeling multiclass vehicular traffic. Each class follows its own speed law and has specific effects on the other classes' speeds. Moreover, general explicit dependencies of the speed laws on space and time are allowed. Solutions are proved to depend continuously -- in suitable norms -- on all terms appearing in the equations, as well as on the initial data. Numerical simulations show the relevance and the effects of the nonlocal terms.
