PIARC (World Road Association), founded in 1909 and comprising more than 120 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads and 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.

A World Road Congress is organised every four years and gathers Ministers, decision-makers and thousands of experts to discuss the current challenges faced by the road sector, innovative approaches and best practices. The 27th edition will be held in Prague (Czech Republic) in October 2023. It will host about 50 sessions, a major exhibition, technical visits and a social program. The next XVII World Winter Service and Road Resilience Congress will be held in 2026 in Chambéry (France).

With knowledge sharing as its primary goal, the Association coordinates Technical Committees and Task Forces which undertake studies, share experience and promote best practices on a broad range of areas of interest to the road and transport sector. An international seminar program is offered to low- and middle-income countries in support of sharing knowledge with high income countries.

The outputs of these groups are a large number of reports, easily downloaded through the online knowledge base at our website.
