Abstract

Road infrastructure is necessary for any country to function and upon which daily life depends. Novel sources of vulnerability, such as climate change or increased interdependencies amongst networks due to technological advancements, can lead to road disruptions. Those disruptions may have catastrophic results if there are no alternative routes to serve traffic. State of the art research in improving transport network connectivity and consequently resilience focuses on adopting a network perspective. However, there is no comprehensive, widespread method for evaluating connectivity and proposing alternative routes to enhance it. Presented herein is a framework that firstly assesses road network connectivity using a “closeness” measure and secondly proposes the development of optimal alternative routes, using a genetic algorithm. The case study examines routes passing by the vulnerable asset of bridges. The results showed a significant improvement of network connectivity and the potential of the method to serve as the basis for updated transport infrastructure planning practices.

简报会:从生态角度重新思考后疫情时代的城市基础设施

道路基础设施对任何国家的运作和日常生活都是必要的。新的脆弱性来源，如气候变化或由于技术进步而增加的网络之间的相互依赖性，可能导致道路中断。如果没有替代路线来服务交通，这些中断可能会造成灾难性的后果。在改善交通网络连通性和弹性方面，目前的研究主要集中在采用网络视角。然而，目前还没有全面、广泛的方法来评估连通性，并提出替代路线来增强连通性。本文提出了一个框架，该框架首先使用“亲密度”度量来评估道路网络的连通性，然后使用遗传算法提出最优替代路线的开发。该案例研究考察了经过桥梁脆弱资产的路线。结果表明，网络连通性有了显著改善，该方法有潜力作为更新交通基础设施规划实践的基础。

期刊介绍： Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
