交通流AR模型的黎曼解

The Riemann Solution of AR Model of Traffic Flow

通过分析交通流AR模型,可以得到三种波:中心疏散波,激波和接触间断.通过这三种波在(ρ,ν)和(w,z)平面上相应地构造出其Riemann(黎曼)解。

By analyzing the structure of model, we can get three basic waves： the centered rarefaction wave, the shock wave and the contact discontinuity. We can construct the Riemann solution on the plane and the plane on the base of three kinds of waves.
