| 摘 要： | 在分析高速公路作业区汇合交通特性的基础上,提出了一个高速公路作业区的宏观动力学交通流模型及模型的离散格式,并用此模型做了汇合交通流的数值模型.数值模拟结果表明,模型可基本反映交通流的物理特性,在描述不均匀密度在车流中的传递,车道数目变化对交通流的影响方面,有一定的优势.

| Abstract: | On the basis of a comprehensive review of the development of macroscopic traffic flow model and the analysis of the traffic flow characteristics of highway work zone merging area,a microscopic traffic flow model for highway work zone merging area is proposed in this paper.Then,the discrete format of this mode is presented.The numerical simulation results show that the proposed model can basically reflect the physical characteristics of highway work zone merging area traffic flow.The model has the advantages of modeling the propagation of different traffic density and the impact of changing of number of lanes on traffic flow. |
