Well-Prepared Projects

This collection of case studies includes 17 cases from 10 different countries participating in this task force, plus one case dedicated to the use of the SOURCE platform in the preparation of transportation projects. It comes after our first report delivered earlier in 2021 in which we reviewed the overall processes and practices taking place in the 10 countries. The objective of this collection is to provide a variety of highly relevant examples from the real life. Each case outlines good practices [...]

Smart Roads Classification

Traditionally, road network classification systems have focused on two fundamentally opposite dimensions: mobility and accessibility. These classification systems have been adapted to the variable circumstances of countries or regions. However, with Connected and Automated Vehicles (CAVs) coming into play, the situation has become quite more challenging than before. Current CAVs consist of diverse Advance Driver Assistance Systems (ADAS) that assist humans in the driving task. The automotive industry [...]

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 [...]

Road Safety - Catalogue Of Case Studies

Knowledge comes from the analysis of successes and un-successes. Case Studies collection represents an important step toward the construction of knowledge. PIARC Case Studies Catalogue contains the description of a set of interventions designed, implemented and operated worldwide to improve road safety in three specific fields: Vulnerable Road Users (VRUs), Human Factors (HF) and interventions in Low- and Middle-Income Countries (LMICs) . Some of them are examples that already proved to be effective [...]
