Welcome on piarc.org!

PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

  • PIARC International Climate Change Adaptation Framework 2023 – Technical Report

    Climate change is a strategic risk to road organisations. Global climate change projections show that there will be gradual changes to average climatic conditions, and changes to the frequency, severity and location of extreme weather events. These climate changes are anticipated to have significant impacts on the design, construction, operation, maintenance and use of global road and transport infrastructure. This is why adaptation principles to address these climate hazard-induced impacts are [...]

  • Climate Change, Resilience and Disaster Management for Roads - Seminar

    Climate change and other hazards have a wide range of implications on the performance of road infrastructure and can cause disruptions to road network operations. For example, extreme rainfall influences the intensity beyond the drainage capacity of roadways, resulting in slope collapses and landslides as well as traffic disruption. These traffic disruptions will lead to an increase in traffic accidents and restrictions. On the other hand, disasters cause significant loss of life each year throughout [...]

  • Climate Change, Other Hazards and Resilience of Road Networks - Collection of Case Studies

    This report contains a collection of case studies related to climate change, other hazards and resilience of road networks. It comprises an introduction, outlining the work program for Technical Committee (TC) 1.4 Climate Change and Resilience of Road Networks, and objectives of two Working Groups within the Technical Committee. These are Working Group 1, which aims to identify uniform and methodological approaches to increasing resilience of roads. It covers hazards and environmental threats within [...]

  • Carbon Neutrality of The Road Sector

    Road transport is vital for society to function and, for the foreseeable future, is expected to remain the dominant mode of transport for people and goods. However, the construction, operation, maintenance and use of the highway infrastructure are responsible for large quantities of carbon emissions. Knowledge of the non-reversible, damaging consequences of climate change has resulted in global acceptance of the need to reduce carbon emissions in all sectors of human activity, including the highways [...]

  • Measures for Increasing the Adaptability of Road Bridges to Climate Change - Literature Review

    The IPCC (Intergovernmental Panel on Climate Change) Working Group 2 report states that changes in climate have caused impacts on natural and human systems on all continents and across the oceans. Key risks from climate change are typically defined as warming trend, extreme temperature, precipitation, extreme precipitation, drying trend, and sea level rise. The impacts of climate change will be regional and depend on the level of adaptation and mitigation achievable. Transportation infrastructure [...]
