  • Disaster Management: The Effects And Management Of Covid-19 Whilst Looking To The Future

    No matter what the disaster is, no matter what the pandemic is, we as road administrators must minimize the disaster impacts to our transportation infrastructure. To share the experiences of disaster management amid COVID-19, PIARC TC 1.5 “Disaster Management” of PIARC and TRB AMR00(2) “Transportation Emergency Management Practices and Innovations Subcommittee” organized a joint webinar on June 30, 2021.

  • Automated Vehicles - Challenges and Opportunities for Road Operators and Road Authorities

    Vehicle Automation – at SAE levels 3, 4 and 5 – is still in a testing phase in most countries. Many tests at level 3 have been performed successfully on open roads without any changes to the road infrastructure and without any observed impacts on congestion. There are various situations which necessitate that a driver takes control of the vehicle – a fall-back solution that is still allowed at level 3, but not at level 4 or 5. It is likely that some support from the infrastructure will be [...]

  • COVID-19: Survey of Impacts and Responses from the Global Roads and Transport Sector

In mid-March 2020, PIARC moved to establish a formal PIARC COVID-19 Response Team to explore the rapid sharing of knowledge and practice between PIARC members in terms of pandemic impacts, associated economic and social crisis and the relevant responses. Activities were rapidly launched [...]

  • Preserve Earthworks and Rural Roads from the Impact of Climate Changes

    This report puts together good practices on the various regional approaches to the impacts of climate change on roads and little hydraulic works. The subject has already been addressed during previous PIARC cycles but more on the general geotechnical aspect. It includes the definition of the climatic parameters that had to be taken into account, the definition of a rural roads and the terminology of the structure of a road (going from embankments, slopes to the pavement layers). The report covers: [...]
