Discover the detailed program and documents of the Prague 2023 Congress which took place at the Prague Congress Center (PCC) from 2 to 6 October 2023.

The XXVIIth World Road Congress was held in Prague, Czech Republic, October 2-6, 2023, under the theme "Together On the Road Again”.

This Congress has been organized in close cooperation between PIARC (World Road Association), responsible for the content of the programme, and the Czech Local Organizing Committee (chaired by the President of the Czech Road Society and co-chaired by the First Delegate of the Czech Republic to PIARC, who is a representative of the Ministry of Transport of the Czech Republic), responsible for the material organization of this Congress on behalf of the Czech Republic and the Slovak Republic.

The Congress attracted 38 Ministerial delegates, 229 exhibitors, 28 national pavilions, over 4,000 delegates and 2,000 students from 120 countries. They were treated to a programme of sessions, workshops, posters, technical visits and social events.

This website presents the final proceedings of the Congress. It contains:

  • The Congress programme, including the detailed programme of each session,
  • National reports produced by PIARC Member Countries for the Strategic Direction Sessions,
  • Individual papers selected by the Technical Committees and Task Forces from among the proposals received following the Call for Papers,
  • PIARC's activity report for each of the years since the last World Road Congress in Abu Dhabi in 2019.

On behalf of the Association, I would like to thank all those without whom this Congress would not have been such a success: the authors of the papers, the facilitators of the sessions and workshops, the Chairs, Secretaries and members of our Technical Committees and Task Forces, the exhibitors, visitors and delegates, our steering bodies and finally, the Czech Road Society and the Ministry of Transport of the Czech Republic, their operational service provider “C-IN”, and their sponsors.
