This page lists Routes/Roads articles of PIARC in the field of road network operations. These publications are classified chronologically.

  • PIARC Prize - Organization and Administration - Identifying and Resolving the Problems of Accessibility to Basic Services Experienced by Rural Communities through the Integrated Rural Accessibility Planning (IRAP) System

    IRAP is a participatory local planning method (developed by the International Labour Organization) based on the concept of rural accessibility. This is understood to mean how easy or difficult it is for rural communities to use, access or obtain basic goods and services. Accessibility is an important factor in rural development and therefore perceived as one of the main factors in poverty, especially in rural areas of developing countries.

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

    This article is a presentation of the report recently published by PIARC Task Force B.2 Automated Vehicles and available on PIARC Website. In the last few years, vehicles with different levels of automation have been being tested all over the world. The automated vehicles will increasingly need to rely on a digital twin of the infrastructure, comprising data transmitted either through connectivity or through digital maps. This scenario implies challenges that have to be faced by road authorities [...]

  • Automated Driving Vehicle and Intelligent Highway in China

    With the rapid development of China’s economy, the scale of expressways is expanding, and the level of intelligence and information is improving. Today, with the rapid development of technology and integration of Internet of Things, big data, artificial intelligence and traditional industries, the intelligent design of transportation infrastructure should integrate innovation and adapt to the traffic streetscape of automated and connected driving vehicles. During the 14th Five-Year Plan period, [...]

  • Digital Transport Infrastructure Interactions with Automated Vehicles

    During the automated part of their journey vehicles rely on on-board systems (cameras, sensors, etc.) and digital feeds from the road infrastructure. This fact calls for a proper maintenance of physical road infrastructure e.g. like markings, signs and signals to ensure a high level of readability by the vehicles’ on-board systems as well as support by infrastructure-to-vehicle services (I2V) to support recognition of physical as well as legal elements, based e.g. on national traffic acts. Here [...]

  • Security Vulnerabilities and Threats Related to CAV Deployment

    The development of the new embedded and on roadside technologies, regardless of traffic type and driving area, have the potential to improve the traffic safety, to minimize the energy consumption, to reduce the pollution emissions, and to optimize the traffic performances. Moreover, the new mobility means have the capability to improve the equitability and allow a mobility access to disabled people. These benefits, however require well thought out implementation of the new services and functions [...]
