Welcome on piarc.org!

PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

Technical Reports Road safety

This page lists technical reports of PIARC in the field of road safety. These publications are classified chronologically.

  • 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 - Technical Report

    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 - Rapport technique

    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 [...]

  • Implementation of National Safe System Policies: A Challenge - Technical Report

    This report provides a contribution to global road safety through a summary of National Safe System Policies and Implementation in relation to the Safe System approach. The report also highlights the steps that low, middle and high-income countries alike can take to accelerate progress towards Safe System outcomes. The report includes a number of key findings from a review and survey of international practice related to national Safe System policies and implementation, which are listed below and [...]

  • Road Safety Evaluations Based on Human Factors Method - Technical Report

    The objective of this report is to instruct responsible road authorities on how to evaluate road safety quality along roads in operation, coupling the well-known reactive approach, based on accident data analysis and high accident concentration sections (or black spots) identification and prioritization, with the pro-active approach, aimed at identifying potentially risky situations before crashes occur. The pro-active approach is a non-accident-based methodology that applies the Human Factors’ [...]
