Abstract In recent years climate change has become a multidisciplinary research topic that addresses the challenges facing transport infrastructure planning, construction and operation. The study of the adaptation of transport systems to new environmental conditions is often based on the interrelated concepts of resilience, vulnerability and criticality. In this paper we assess the criticality of sections of Spain's inland transport network under the effects of changing climate scenarios obtained from a specific climate projection (using the time periods 2010–2020 and 2045–2055). The functionality of the transport system is characterised here in terms of territorial accessibility. The results identify and locate the most critical stretches of the Spanish transport network. In general terms, the most relevant sections in regard to accessibility will not be exposed to the greatest changes in climate variables. Up to 2.8% of the roads and 5.9% of the railways that contribute most significantly to the territorial accessibility of the transport system will undergo the greatest variations between climate scenarios. This paper contributes to this field of research by developing a screening tool that represents a valuable instrument for the infrastructure decision-making process at the strategic level. Action areas for proactive adaptation measures can be identified in order to reduce impacts and costs, while prioritising the maintenance or reconstruction of the most critical stretches in the case of a future climate event.

由于气候情景确定西班牙交通系统的关键部分

摘要 近年来,气候变化已成为解决交通基础设施规划、建设和运营面临的挑战的多学科研究课题。交通系统对新环境条件的适应性研究通常基于复原力、脆弱性和临界性等相互关联的概念。在本文中,我们评估了在从特定气候预测(使用 2010-2020 年和 2045-2055 年的时间段)获得的气候变化情景影响下西班牙内陆交通网络部分的重要性。交通系统的功能在这里体现在地域可达性方面。结果确定并定位了西班牙交通网络中最关键的路段。笼统,与无障碍相关的最相关部分不会受到气候变量的最大变化的影响。多达 2.8% 的公路和 5.9% 的铁路对交通系统的领土可达性贡献最大,将在气候情景之间经历最大的变化。本文通过开发一种筛选工具为战略层面的基础设施决策过程提供了一种有价值的工具,从而为这一研究领域做出了贡献。可以确定主动适应措施的行动领域,以减少影响和成本,同时在未来发生气候事件时优先维护或重建最关键的路段。9% 对交通系统的领土可达性贡献最大的铁路将在气候情景之间经历最大的变化。本文通过开发一种筛选工具为战略层面的基础设施决策过程提供了一种有价值的工具,从而为这一研究领域做出了贡献。可以确定主动适应措施的行动领域,以减少影响和成本,同时在未来发生气候事件时优先维护或重建最关键的路段。9% 对交通系统的领土可达性贡献最大的铁路将在气候情景之间经历最大的变化。本文通过开发一种筛选工具为战略层面的基础设施决策过程提供了一种有价值的工具,从而为这一研究领域做出了贡献。可以确定主动适应措施的行动领域,以减少影响和成本,同时在未来发生气候事件时优先维护或重建最关键的路段。本文通过开发一种筛选工具为战略层面的基础设施决策过程提供了一种有价值的工具,从而为这一研究领域做出了贡献。可以确定主动适应措施的行动领域,以减少影响和成本,同时在未来发生气候事件时优先维护或重建最关键的路段。本文通过开发一种筛选工具为战略层面的基础设施决策过程提供了一种有价值的工具,从而为这一研究领域做出了贡献。可以确定主动适应措施的行动领域,以减少影响和成本,同时在未来发生气候事件时优先维护或重建最关键的路段。
