摘　　要：在Zhang模型的基础上,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.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 traffic flow models and the corresponding finite difference scheme of these models--Godunov scheme. The derivation of these models is based on the application and popularization of Zhang non-equilibrium traffic 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 traffic flow well.
