A standard conservation form is derived in this paper. The hyperbolicity of Helbing’s fluid dynamic traffic flow model is
proved, which is essential to the general analytical and numerical study of this model. On the basis of this conservation
form, a local discontinuous Galerkin scheme is designed to solve the resulting system efficiently. The evolution of an unstable
equilibrium traffic state leading to a stable stop-and-go traveling wave is simulated. This simulation also verifies that
the model is truly improved by the introduction of the modified diffusion coefficients, and thus helps to protect vehicles
from collisions and avoide the appearance of the extremely large density. 相似文献
