Abstract

Reliable road-network performance is important for socio‐economic development and emergency response. This paper investigates road network vulnerability by assessing traffic disruptions on mobility in the Piana del Sele and Irpinia, two inner regions of Campania (Italy). Different scenarios of traffic disruptions were simulated using the PTV-Visum software. With the use of an accessibility indicator and a link importance index, the network’s weaknesses and strategic routes were identified. The most critical scenario for the Piana del Sele involves the closure of the “Barrizzo” bridge on the SS18, resulting in an average accessibility reduction of 2.22%, affecting 27 homogeneous traffic zones. In Irpinia, the worst scenario is the closure of the tunnel along the A16 motorway in the municipality of Montemiletto, with an average accessibility reduction of 2.42%. Stakeholders, such as municipal administrators and transportation agencies, who must manage emergencies by suggesting evacuation plans or scheduling infrastructure maintenance interventions, can benefit from using this study as a useful decision-making tool.

交通中断对内坎帕尼亚地区道路网络可达性和脆弱性的影响

可靠的道路网络性能对社会经济发展和应急响应至关重要。本文通过评估Piana del Sele和Irpinia两个坎帕尼亚（意大利）内陆地区的交通中断对交通的影响来研究道路网络脆弱性。使用PTV-Visum软件模拟不同的交通中断情况。利用可达性指标和链接重要性指数，确定了网络的弱点和战略路线。对于Piana del Sele来说，最关键的情况是关闭SS18上的“Barrizzo”桥，导致平均可达性减少2.22%，影响27个同质交通区域。在伊尔皮尼亚，最糟糕的情况是沿着蒙特米莱托市A16高速公路的隧道关闭，平均可达性减少2.42%。市政管理者和交通运输机构等利益相关者必须通过提出疏散计划或安排基础设施维护干预措施来管理紧急情况，他们可以从将本研究作为有用的决策工具中受益。

期刊介绍： Description The journal has an applied focus: it actively promotes the importance of geographical research in real world settings It is policy-relevant: it seeks both a readership and contributions from practitioners as well as academics The substantive foundation is spatial analysis: the use of quantitative techniques to identify patterns and processes within geographic environments The combination of these points, which are fully reflected in the naming of the journal, establishes a unique position in the marketplace. RationaleA geographical perspective has always been crucial to the understanding of the social and physical organisation of the world around us. The techniques of spatial analysis provide a powerful means for the assembly and interpretation of evidence, and thus to address critical questions about issues such as crime and deprivation, immigration and demographic restructuring, retailing activity and employment change, resource management and environmental improvement. Many of these issues are equally important to academic research as they are to policy makers and Applied Spatial Analysis and Policy aims to close the gap between these two perspectives by providing a forum for discussion of applied research in a range of different contexts Topical and interdisciplinaryIncreasingly government organisations, administrative agencies and private businesses are requiring research to support their ‘evidence-based’ strategies or policies. Geographical location is critical in much of this work which extends across a wide range of disciplines including demography, actuarial sciences, statistics, public sector planning, business planning, economics, epidemiology, sociology, social policy, health research, environmental management. FocusApplied Spatial Analysis and Policy will draw on applied research from diverse problem domains, such as transport, policing, education, health, environment and leisure, in different international contexts. The journal will therefore provide insights into the variations in phenomena that exist across space, it will provide evidence for comparative policy analysis between domains and between locations, and stimulate ideas about the translation of spatial analysis methods and techniques across varied policy contexts. It is essential to know how to measure, monitor and understand spatial distributions, many of which have implications for those with responsibility to plan and enhance the society and the environment in which we all exist. Readership and Editorial BoardAs a journal focused on applications of methods of spatial analysis, Applied Spatial Analysis and Policy will be of interest to scholars and students in a wide range of academic fields, to practitioners in government and administrative agencies and to consultants in private sector organisations. The Editorial Board reflects the international and multidisciplinary nature of the journal.
