| 摘 要： | 在Zhang模型的基拙上，研究了有侧向驶入、驶出的单车道和多车道的情形，给出了这些情况下的非平衡交通流模型及相应的Godunov型有限差分格式。这些模型是Zhang的非平衡交通流模型在更广的范围内的应用与推广，它们和Zhang的模型具有同样的优势:不但克服了LWR模型和PW模型的缺陷，而且能够对现实交通流做出较好的预测。

| Abstract: | Based on Zhang model, this paper investigates the condition of single lane and multilane when there are lateral entry and exit roads, and presents their non-equilibrium trafic flow models and the corresponding finite diference scheme of these models--Godunov scheme. The derivation of these models is based on the application and popularization of Zhang non-equilibrium trafic flow model in the larger scale. These models have the same advantage with Zhang model: they not only overcome the flaw of LWR model and PW model, but also forecast the trafic flow well. |
