地点：新主楼A716
摘要：基于经典路段交通流基本图模型（即流量-密度-速度模型），宏观交通流基本图描述路网聚合层面的交通流动力学关系，为评价路网运行状态、区域交通优化控制以及城市交通系统规划等方面提供了新视角及方法论。宏观交通流基本图模型（MFD）近年来是交通理论研究领域尤其是交通流理论方向上的热点问题，其形式简洁，功能巧妙，其理论特性、模型属性以及工程应用受到广泛的关注和拓展。本次学术交流旨在和相关科研工作者对MFD的理论基础开展相对深入的交流，从MFD的概念起源、数据体现、理论推导以及决策支持四个方面探讨MFD对交通系统建模、大数据分析以及路网运行与规划设计的贡献。通过本次交流，希望可传达如下信息：MFD模型形式简约且简洁但其理论不简单，其和传统中微观模型有共同目标但面向不同层面交通流问题，其可从多方面支持城市交通系统运行与优化有多元的功效。
主讲人简介：Dr. Nan Zheng is a Senior Lecturer (tenured) in the Institute of
Transport Studies, Department of Civil Engineering at Monash University. Before
his current appointment, Dr. Zheng was an Associated Professor in the School of
Transportation Science and Technology at Beihang University. He spent nearly
ten years in Europe, to obtain his Master and PhD degrees at TU-Delft and EPF-Lausanne
respectively, and Post-doc at ETH-Zurcih.His publications appear in leading
transportation journals such as Transportation Research Part A/B/C, and his
works are invited to present in prestigious transportation conferences such as
ISTTT andIEEE-ITSC. Dr Zheng’s research interests include modeling and
operation of urban traffic systems, emerging vehicle and mobility technologies,
transportation big data analytics, and novel planning and management with CAVs.
Dr.Zheng is actively looking for PhD students with background in operational
research, computer science and mathematical modeling. Students who are willing
to carry out short-term exchanges at Monash are also welcome.
