8. Best practices for increasing resilience in road networks

  • IP0273 - A framework to prioritize critical road segments for climate-resilience investments
    Sohouenou Philippe

    With climate change, the impacts of natural hazards (such as floods, snow events and landslides) on road networks and mobility could worsen. Hence, strengthening the resilience of road infrastructures to natural hazards is more critical than ever before. To reach this objective, the design, operation and maintenance of road infrastructures should be informed by climate, transport and infrastructure [...]

  • IP0382 - A simplified resilience approach for assessing road projects in Norway
    Husdal Jan

    The effect of various road project solutions on societal safety and security is usually assessed as a part of the general risk analysis. The aim is to avoid all situations where mobility would be impaired, especially accessibility of services of vital importance. The paper presents a method that was developed for assessing societal safety and security on road projects and provides examples of its [...]

  • IP0352 - Coordination of Resilience Initiatives Between REAAA and PIARC
    Evans Caroline

    It is recognised that the impacts of climate change, natural disasters and man-made events on road transport networks result in significant economic, social and environmental impacts. These events also affect the vulnerability of road networks and the ability to provide efficient and effective access and mobility of goods, services and people in our society in the short and longer-term. The topic [...]

  • IP0376 - Management of research and innovation projects for climate change adaptation of road infrastructure investments in cold climate, from a Swedish perspective
    Friberg Fredrik

    Recent decades have seen an increased attention towards the threat of climate change. Resilience and climate change adaptation are major challenges of the infrastructure construction sector. The national road administrations are vital as clients and regulation-writing authorities. In addition, large public buyers such as road administrations, represent a large proportion of the construction market. [...]

  • IP0180 - Prioritizing and implementing avalanche mitigation measures for the Trans-Canada Highway through Glacier National Park
    Jaime Sanderson

    The Trans-Canada Highway (TCH) runs across the whole of Canada and is the most important highway for the nation. The TCH is threatened by 135 avalanche paths through Glacier National Park (GNP) causing an average of 74 hours of highway closures per winter and significant risk to highway users. Winter Average Daily Traffic (WADT) increases annually, and without additional mitigation, avalanche risk [...]

  • IP0365 - Reducing vulnerability to natural disasters through Resilient Transport Infrastructure Asset Management
    López Oliver David

    The need of resilient asset management is more and more recognized among the different administrations and stakeholders. Climate change is leading to a more extreme environment and increasing the recurrence rate of natural hazards and extreme events, making infrastructures subject to actions to which they had not necessarily been designed for. Vulnerability assessments to anticipate potential failures, [...]

  • IP0338 - Reliability, Risk and Resilience of transport infrastructures in Germany: Results of the first research period (2016-2019) of the BMVI Network of Experts “Knowledge – Ability – Action”
    Anastassiadou Kalliopi

    Considering the increase of extreme weather events due to climate change and the unfavorable age distribution of transport infrastructure in Germany, more efforts are required to optimize and coordinate maintenance, upgrading and replacement of existing infrastructure. The proof principles and safety specifications applied in the construction of transport infrastructures often do no longer meet today’s [...]

  • IP0101 - Resilience of transport networks affected by erosion and marine submersion: towards an integrated and concerted management of infrastructures in coastal areas
    Ponsart Carline

    Since 2006, the Climate Change Action Plan and Quebec's Government Climate Change Adaptation Strategy have laid the groundwork to initiate proactive actions for knowledge development, allowing synergy between organizations, institutions and ministries towards a common goal. Outstanding efforts have been invested, particularly in the coastal zone of the St. Lawrence Estuary and Gulf of St. Lawrence, [...]

  • IP0026 - Road resilience and sustainable development, the contribution of transport to climate action and energy transition
    Dimnet Eric

    Resilience is a cross cutting issue within PIARC’s 2020/2023 strategic plan. The notion is present in the terms of reference and workplans of several Technical Committees (TC) dealing with the issue from a bottom up or a top down point of view. In addition, PIARC has decided to produce an introductory manual on resilience of road transport. The purpose of the contribution is to present this manual, [...]

  • IP0362 - Test Sections for the Periodic Conservation of the Mexican Highway Network
    Ramos Herrera Jose Francisco

    Mexico has a Road Network designed with legal charges in accordance with its Official Standar that govern weights and dimensions, pavements that are exposed in less than 10 years to more than 200 million ESAL's. However, it is common to have loads higher than the legal ones circulating on the National highway network. The current conditions in the economy affect the investment budget for the conservation [...]

  • IP0084 - The World Bank’s support to road network resilience mainstreaming and improvement
    Dimitropoulos Ioannis

    Building climate-resilient road transportation systems is essential to the global goals of ending extreme poverty and promoting shared prosperity. Through the engagement of its partner countries, the World Bank has accumulated a wealth of global expertise in improvement of road network resilience to climate change and extreme weather threats, aging-infrastructure risks, and natural disasters. The [...]

  • IP0245 - Towards a more resilient spanish road network
    Alonso Mónica

    Various studies state the increasing impacts related to weather in infrastructures, both extreme events and slow-onset processes. Road transport infrastructures are not an exception, finding that several assets are becoming more vulnerable to climate change all over the world. In Spain, 45% of the main network and 4% of the total length is somehow impacted by climate (CEDEX, 2018). These impacts affect [...]
