Dear PIARC family, dear PIARC representatives, dear congress delegates, dear sponsors, dear exhibitors, dear students, dear friends!

2 months ago we were enjoying sunny Prague being “Together on the road again” at the 27th WORLD ROAD CONGRESS.

Today we are presenting you this summary with some 30-40 cm of snow around the city and with woollen socks on our feet.

The congress is now a thing of the past, and as hosts from the Czech and Slovakian region, we are committed to devising fresh projects on the World Road Congress platform.

As the Chair of the Local Organising Committee, I am honoured by this opportunity to express gratitude to all our esteemed attendees for their invaluable support in turning this congress into a historic and unforgettable event.

We are delighted to have welcomed over 4000 delegates and guests, along with 2000 students, more than 30 national pavilions and over 300 exhibitors. The Congress hosted and increased our expertise with 88 sessions, 16 workshops and 15 technical visits!

For 5 days we brought 120 countries together, we spoke together, listened to and inspired each other, we studied and discussed together, we learned and laughed together, we ate and drank and danced and sang and I believe that we have created the platform for making the road infrastructure and the overall mobility better!

By achieving this, I sincerely hope, that we have established the basis and the means to make this world, enduring many unfortunate and harsh situations, a better place.

Please refer to the links below featuring hundreds of photographs and numerous videos helping us remind that we can, and we have to, all coexist and collaborate.

On behalf of our team of over 100 individuals, I express my genuine gratitude to all of you for giving us the opportunity to be a part of the PIARC history for the second time.

Word from the President of PIARC

It is my pleasure to invite you to the PIARC XXVIIth World Road Congress that will take place in Prague, Czech Republic. The Congress will take place at the Convention Centre from 2–6 October 2023.

The theme of the Congress is “Prague 2023 – Together on the road again”. An apt theme given that the pandemic has kept us apart for far too long.

Development and economic growth are requirements for countries to prosper. However, the pandemic and the challenges posed by having to consider resilience in the supply and maintenance of road infrastructure taught us to move past the pragmatism of this approach. Our approach should encompass social goals, work toward reducing poverty, and promote innovation that leads to the improvement of the quality of life. Road infrastructure, as a community asset, has shown itself through the years to be a powerful tool in improving the quality of life and promoting social cohesion. However, ensuring sustainability thereof requires integrated, participating, and inclusive processes to achieve the desired results.

It is imperative that developed and developing countries alike join hands and take responsibility for our shared goals of sustainable development and push back the frontiers of poverty. Road infrastructure has always played a pivotal role in enabling socio-economic development of societies.

PIARC since its inception has taken the lead in gathering the world road community at its Congresses to share knowledge, experiences, and cement bonds between its diverse group of members. Although the Strategic Plan directs and guides the activities of PIARC during a given cycle, its main objective of international cooperation and technology transfer has always been retained.

During this cycle, the Strategic Plan has, inter alia, comprises four themes, namely:

• Road Administration;
• Mobility;
• Resilient Infrastructure; and
• Safety and Sustainability.

The Congress programme features the presentation of the results of the work undertaken by PIARC’s 24 Committees and Task Forces, as well as several specialized sessions and workshops dealing with topics of current and future interest and a large exhibition in which road administrations, equipment and service providers, consultants and road-related organizations will be present. Ministers will be present to share their views on the status and future of roads and road transport.

We also invite experts from around the world, researchers as well as practitioners, to submit articles in answer to our International Call for Papers and to present their views on the technical, social, and  economic best practices related to the road sector.

This World Road Congress will see a return to an in-person event, and it will thus offer all road professionals a unique opportunity to discuss information on current trends and challenges for roads and road transportation all over the world.

On behalf of PIARC, I express my sincere gratitude to the Government of the Czech Republic for their commitment to host and organize the Congress and their efforts to ensure that the event is a great success.
I invite you to mark this event on your agenda and look forward to meeting you in Prague in 2023.

A Word from the Chair
of the Slovak Road Association

Dear Colleagues,

I am delighted that the World Road Congress will take place in Prague in 2023, and I believe this is also thanks to the fact that Slovakia and the Slovak Road Association supported Prague’s candidacy. It only goes to show the extraordinary level of cooperation between Slovakia and the Czech Republic and,
above all, between our partner road associations.

We are proud to participate in the organisation of the congress and, with a little bit of nostalgia, we remember the era when our two countries, together in what was then Czechoslovakia, hosted the Road Congress in 1971.

Once every four years, the World Road Congress brings together experts from all over the world, offering an exceptional opportunity to professionals in the road construction and road management industries – researchers, road administrators, designers, construction companies, and university teachers and students.

There are multiple ways to take part in this major event, ranging from the chance to present a lecture on one’s work to attending the Congress to benefit from the latest insights and know-how in the field, networking with world experts or introducing one’s business, organisation, or country in one of the exhibition booths.

I am immensely honoured to invite you to the most prestigious industry event organised by PIARC, and I hope you will avail yourself of this unique opportunity.

I look forward to meeting you at the World Road Congress in Prague on 2–6 October 2023.
