Modeling Multilane Traffic with Moving Obstacles by Nonlocal Balance Laws

We introduce a Follow-the-Leader approximation of a nonlocal generalized Aw--Rascle--Zhang (GARZ) model for traffic flow. We prove the convergence to weak solutions of the corresponding macroscopic equations deriving $L^\infty$ and BV estimates. We also provide numerical simulations illustrating the micro-macro convergence and we numerically investigate the nonlocal to local limit for both the microscopic and macroscopic models.
