Road Transportation as complex adaptive systems: An exploratory conceptual framework to study road traffic patterns, accessibility, mobility, connectivity and congestion/emission

该奖项是在交通运输行业工程探索性研究(ETI)项目征集下颁发的。我们建议将交通运输作为复杂适应系统(CAS)来研究。我们的目的是对公路和公路运输系统的各个方面进行探索性研究和分析。探索性研究的主题和一些用于分析它们的方法借鉴了许多学科。具体内容如下：(1)基于算法熵(Kolmogorov熵)的城市日常公路交通模式的隐序性。(2)交通网络的连通性是从河网和分维几何模型中衍生出来的分维。(3)基于位置和键渗流理论的可达性和流动性。(4)基于进化生物学NK模型的长期流量模式的出现。(5)拥塞是基于自旋玻璃理论的二阶相变，而排放是分布式智能体模拟神经网络的集体结果。(6)基于自组织临界模型的可修改区域单位问题(MAUP)和城市活动/交通系统。我们相信，交通系统的跨学科研究和分析将提供对复杂性和交通领域的洞察。希望这将反过来激发人们对开发新的交通流和运输模型的兴趣，这些模型解决了微观层面的相互作用如何导致宏观层面的行为和相变现象的问题。

This award is made under the Exploratory Research on Engineering the Transport Industries (ETI) program solicitation We propose to study transportation as complex adaptive systems (CAS). It is our intent to carry out exploratory research and analysis of various aspects of highway and road transportation systems. The topics for exploratory research and some of the methods used to analyze them are borrowed from many disciplines. They are as mentioned below: (1) The hidden order in apparently random daily urban highway traffic patterns based on algorithmic entropy (Kolmogorov entroy). (2) Connectivity of Transportation Network as a fractal dimension derived from river flow networks and fractal geometry models. (3) Accessibility and mobility based on site and bond percolation theory. (4) Emergence of long-term traffic patterns based on NK models of evolutionary biology. (5) Congestion as a second order phase change based on spin glass theory and emission as a collective outcome of distributed agents modeled after neural networks. (6) Modifiable Areal Unit Problem (MAUP) and urban activities/transport systems based on models of self-organized criticality.We believe that the interdisciplinary research and analysis of transportation systems will offer insights into Complexity and Transportation fields. It is hoped that this would in turn spur interest in development of new traffic flow and transportation models that address the issue of how micro level interactions give rise to macro level behavior and the phenomenon of phase change.
