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 Design of inter-urban roads

This page lists technical reports of PIARC in the field of design of inter-urban roads. These publications are classified chronologically.

  • State of the Art in Road Design Standards - Literature Review

    This literature review is the first of two planned publications of PIARC Task Force 4.1 “Road Design Standards” in the period 2020 – 2022. PIARC considered importance of comparison international road design standards to check their updated status and the degree of their readiness to face the forthcoming innovations in the road mobility. The report presents a literature review in the field of road design standards based on reviewing reports, guidelines, and research papers on the subject matter. [...]

  • 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 [...]

  • Low Cost ITS - Technical Report

    The Low Cost ITS concept was introduced for the first time during PIARC 2012-2015 cycle. The concept described ITS services that were attractive to resource limited or Low- and Middle-Income Countries (LMICs). This was possible because of the recent emergence of inexpensive technological solutions including information systems based on the collection of probe vehicle data or information harvesting from social networks-based software applications. However, the concept was not formally defined. Upon [...]

  • Vulnerable road users: Diagnosis of design and operational safety problems and potential countermeasures

    Following the World Health Organisation, nearly half of those dying on the world's roads are vulnerable road users (VRU). This proportion is much greater in low- and middle-income countries, because of the greater variety and intensity of traffic mix and the lack of separation from other road users, than in high-income countries. Compared to other road users the vulnerable user group is particularly exposed to injury as they are not protected by a vehicle shell. For years, pedestrians, cyclists, [...]

  • Road safety audit guidelines for safety checks of new road projects

    This guideline is a comprehensive catalogue of design safety problems and countermeasures that outlines the common types of design failures in a definitive guide for road engineers and professionals working in the road transport sector. With the UN Decade of Action soon to be launched by the World Health Organisation and a commitment to reduce road deaths through careful planning and innovative solutions the guidelines provide an excellent resource for road agencies and the private sector. The guidelines [...]
