  • Renewal and Rejuvenation of Aging Infrastructure - Technical Report

    For the purpose of this research, “aging infrastructure” is defined as any road related assets that are approaching the end of their expected service life or have prematurely deteriorated in condition and are no longer providing the required level of service. This may be due to shorter service life due to assets not performing as expected, changing usage of the network, changing environment since design and construction of assets, and / or underinvestment in maintenance that has created a backlog [...]

  • Uniform and Holistic Approaches to Resilience: Climate Change and Other Hazards - Technical Report

    This report focuses on the resilience of road networks in the context of climate change and various hazards, emphasizing the need to consider environmental risks, chronic threats, and acute shocks. Natural hazards are highlighted as a significant global challenge, with extreme weather events and human-induced environmental damage considered the most detrimental threats to road infrastructures. The report calls for urgent attention and strategic planning, strongly encouraging the inclusion of an [...]

  • Optimizing Road Network Operations Using Big Data - Technical Report

    Road network operators are increasingly embracing technology and developing digital infrastructure to effectively manage road networks. At the same time, road users are using technology to enhance trip efficiency and safety, while vehicles on the road network are utilizing an increasing amount of technology to manage fleets, improve safety, and move toward automated operations. These trends have led to an increase in available data for road network operators, which can support improved decision-making. [...]

  • New Mobility and Road Infrastructure - Interim Report

    PIARC has been concerned, for some time, about the challenges and opportunities presented by Connected and Autonomous Vehicles for Road Network Operators. These were explored by two Task Forces (B.1 and B.2) between 2018 and 2020 but have also now been overtaken by the rapid and disruptive development of a wider range of new mobility technologies, digital and service concepts. The new forms of mobility refer both to the new vehicle types and technologies that are starting to circulate on streets [...]
