Congress Themes

There will be over 50 technical sessions under two complimentary themes: Winter Service and, new for 2022, Road Resilience (in all seasons). This is reflected in the 15 topics of the international call for papers.

Winter Service Theme:

Topic 1: Extreme winter situations in cold climate areas

How can road agencies cope with challenges and plan for emergencies during extreme winter events when standard response plans may no longer be valid. In many countries, there are roads in areas with extreme conditions, such as mountain passes requiring convoys, roads in open areas exposed to snowdrift, and roads vulnerable to avalanches. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 2: Effect of climate change on winter service

The effect of climate change on winter service is dominated by climate and local weather events. How will climate change affect winter conditions, and how will it affect winter service? More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 3: Road weather information

Maintenance Decision Support System (MDSS), Intelligent Transportation Systems (ITS), and use of mobile data are the new tools to assist in delivering winter service operations and providing information to the public. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 4: New technologies and methods in winter service

Winter service evolves over the years with ongoing development and research. This topic covers all subjects concerning innovation in techniques and technologies in winter service. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 5: Winter maintenance management

Winter maintenance management administration of winter service activities involves planning and organizing many functions of road agencies and requires significant resources. Winter service is part of the operational strategies of road administrations. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 6: Road user communications and connected and autonomous vehicles during winter

What are the effects winter conditions will have on connected and autonomous vehicles? What are the effects of connected and autonomous vehicles on winter service? More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 7: Winter service in urban areas

Maintenance of the urban network can vary from major highways to dead-end roads where space is very limited. Snow and ice in winter have an impact on different types of transport and their connections. More information on this topic, and all the others, is in Congress Bulletin 1.

Resilience Theme:

Topic 8: Best practices for increasing resilience in road networks.

Best practices in resilience should focus on actions that help to prepare, respond, recover and adapt to future threats/hazards including climate change and extreme weather, aging infrastructure, natural disasters, man-made disasters, cyber-physical threats. Economic, social, and environmental aspects of resilience management, and the cost-effectiveness of proven adaptation strategies, should be part of the solution. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 9: Disaster and Risk Management

The current trend in managing catastrophic events includes interacting with the public and other organizations to produce better outcomes in incident management, not only giving priority to securing infrastructure. Sharing a wide range of data and available information between road managers and road users has become key to disaster and risk management. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 10: Improving resilience of Road Network Operations through ITS and new technologies

When disruptions in the transportation system occur, the ability of road operators to deliver information quickly to road users may be compromised therefore jeopardizing road operations. New technologies offer new possibilities to engage with road users and avoid disruptions. Big data and advanced analytics such as AI can help road operators, especially in times of crisis and emergencies, through better information sharing in real time. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 11: Resilient pavements

The use of advanced pavement management approaches to mitigate natural or man-made disasters may increase resilience as the climate changes. Theoretical modelling, laboratory research, in-situ performance evaluation, or case studies may form the basis of abstracts for this topic. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 12: Bridge resilience considering natural hazards

Seismic events have caused severe damage to road bridges in seismic areas, resulting in closed road networks. The effects of climate change on bridge design and maintenance are becoming more visible with mitigation necessary to accommodate climate change effects. Building climate-change resilient bridges or seismic retrofit techniques to enhance the resilience of road bridges will be explored. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 13: Resilience of Earth Structures to natural hazards

Specific measures are sought in design and construction of earth structures to prevent the effect of natural hazards on their performance over their design life. Abstracts are invited from any geographical location and involving any techniques that have been used in the past to improve earth structure performance irrespective of the complexity of the method employed. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 14: Resilience: measures to keep a road tunnel safely available for traffic under varying circumstances

In the context of road tunnels, resilience could be described as the ability to keep the tunnel safely available for traffic, during various abnormal situations such as traffic incidents, technical malfunctions, extreme weather conditions, other natural and human hazards, or maintenance and refurbishments. More information on this topic, and all the others, is in Congress Bulletin 1.

Topic 15: Resilience through asset management and security

PIARC’s Strategic Plan recognizes resilience as one of the global issues that it should address. This topic relates to PIARC’s works on:

• Asset management and resilience OR
• Security aspects of road resilience

This topic will gather best practices and approaches of Road Asset Management measures to improve the resilience of the road infrastructure. Resilience of road network is of high importance to ensure that road user costs and socio-economic costs are reduced in case of hazards. This topic will also address the general principles of a security-minded approach as well as the technical and operational practices to protect against a range of physical and cyber threats.
