Felisia Angela Chiarello, Paola Goatin, Elena Rossi

摘要:

证明了交通流模型中一类具有非局部流的标量守恒律方程熵弱解的稳定性。我们得到了解对核函数、速度和初始数据的依赖性的估计。通过变量加倍技术,从熵条件出发,得到了系统的稳定性.最后,我们提供了一些数值模拟,说明了上述依赖性的一些成本泛函来自交通流的应用。

英文摘要:

We prove the stability of entropy weak solutions of a class of scalar conservation laws with non-local flux arising in traffic modelling. We obtain an estimate of the dependence of the solution with respect to the kernel function, the speed and the initial datum. Stability is obtained from the entropy condition through doubling of variable technique. We finally provide some numerical simulations illustrating the dependencies above for some cost functionals derived from traffic flow applications.
