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 Urban Mobility

This page lists technical reports of PIARC in the field of urban mobility. 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 [...]

  • Traffic Noise – Best Practice Guide - Technical Report

    In recent years, knowledge about the health effects of traffic noise has grown substantially. Many studies have found that long-term exposure to traffic noise is associated with various health impacts such as sleep disturbance, cardiovascular disease and depression. While there remain knowledge gaps concerning the risk for particular noise profiles, there is sufficient evidence to suggest that a large proportion of people living within major urban centres is at risk due to excessive noise level [...]

  • Journey Time and Travel Reliability - Technical Report

    Travel time reliability has been put by all stakeholders in the transport arena at the centre of attention: transport planners, operators and users agree on the need to take actions for more reliable transport systems. Although the framework is clear in terms of the stakeholders’ claims, the theoretical knowledge about reliability is even internationally not exhaustive and the same definition of the term is not intuitive and seems to differ from country to country. As a position-fixing for its [...]

  • Sustainable Multimodality in Urban Regions - Technical Report

    Globalization and specialization have enabled cities to flourish and have led to the concentration of activities and populations, resulting in an increase in urban transport needs and a scarcity of public space. In these urban areas characterized by high population and employment densities, congestion of transport systems is the rule and the sharing of public space is a necessity. Moreover, in a context of scarce public finances, new developments were becoming increasingly difficult to implement, [...]

  • 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 [...]
