报告摘要:

Emerging connected and automated vehicle technologies present unique challenges and opportunities in the modeling of nonlocal inter-vehicle interactions and their effects on traffic flows. This talk investigates a particular nonlocal traffic flow model, revealing that asymptotic stability of traffic flow is attainable under suitable assumptions on nonlocal information utilization. Simultaneously, we present a family of numerical schemes for the model that demonstrate robustness with respect to changes in the nonlocal horizon parameter. With suitable discretization of the nonlocal integral, the convergence of numerical solutions is shown to lead towards the weak entropy solution of the respective local model as both the mesh size and the nonlocal horizon parameter approach zero. The findings may serve to inform the development of future driving algorithms for connected vehicles.
