We introduce a second order model for traffic flow with moving bottlenecks. The model consists of the × 2$ Aw-Rascle-Zhang system with a point-wise flow constraint whose trajectory is governed by an ordinary differential equation. We define two Riemann solvers, characterize the corresponding invariant domains and propose numerical strategies, which are effective in capturing the non-classical shocks due to the constraint activation.

Comparison between the solution obtained with both conditions (16) and (17) (the dot-dashed line) and the one obtained when only (17) is enforced (the continuous line): the first has undesirable oscillation, while the latter is correct. The initial data are:
