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.

  • Adaptation Methodologies and Strategies to Increase the Resilience of Roads to Climate Change - Technical Report

    Climate Change is anticipated to have a significant impact on the design, construction, maintenance and operation of global road infrastructure. The IPCC Climate change projections indicate that the earth will become warmer, some regions will become wetter and some will become drier, sea levels will rise and storm surge height will increase, snow cover and extent of sea ice will reduce, and the frequency and severity of extreme weather events will increase. This in turn will result in significant [...]

  • Positive Energy Roads

    Transport infrastructure, and particularly road infrastructure, is critical to the economic growth of countries and as such attracts significant investment. The social and economic benefits of providing road infrastructure are well documented, but it is increasingly being recognised that the processes by which the infrastructure is designed, constructed, maintained and operated also need to minimise negative impacts such as pollution and greenhouse gas emissions. A key challenge for road transport [...]

  • Electric road systems: a solution for the future?

    It is looking increasing likely that electric vehicles will play a major role in the future of road transport. While commercial electric vehicles exist their uptake has been limited due to high purchase costs, limited battery range, and a lack of charging convenience. Furthermore, while developments are underway, electric and hybrid drive trains are yet to be efficiently integrated with heavy goods vehicles (HGVs). A novel way to overcome such challenges are Electric Road Systems; a branch of technologies [...]

  • Appraisal of Sustainability of Transport Infrastructure Plans and Programs

    This report gives a scanning overview of the current state of the art on the topic of the appraisal of sustainability within the development of transport plans and investment programs, respectively the extent to which decisions made in this context have taken account of sustainability. The report is based on the result of a questionnaire done within the technical committee and structured around survey findings and case studies. The scope of this technical report was investigated how the sustainability [...]

  • Transport Strategies for Climate Change Mitigation and Adaptation

    The transport sector is a major and quickly growing source of greenhouse gas emissions. Since 1970, greenhouse gas emissions from the transportation sector have more than doubled, increasing at a faster rate than any other end-use sector, and on-road greenhouse gas emissions have more than tripled, accounting for about 80 percent of the increase in total transport greenhouse gas emissions. Global transport greenhouse gas emissions are expected to increase faster than other sectors without aggressive [...]
