and critical density of second macroscopic trac model METANET are identi-
fied form the linear style equation of static speed equation. Its effectiveness is
demonstrated through numerical examples.
In an ongoing work, we perform further analysis and simulations based on real
life highway data, moreover, in future we will integrate the on-line identification
results with some important trac control strategies, such as model predictive
control (MPC), adaptive control and model-free control, so as to further improve
the real-time highway trac automation feasibility.
