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.

  • Road in Desert Areas

    Drafted by the PIARC Technical Committee on Roads in Developing Regions, this report provides information on the construction and maintenance of roads in desert areas.

  • Techniques for Motorway Widening

    The seemingly inexorable growth of traffic has led to the expansion of the motorway systems in North America and Europe. Increasingly the capacity of existing motorways is being enhanced by the construction of additional lanes. The planning of widening works should take account of the special nature of a live motorway site, which imposes constraints on working space and access, and the acute pressure to commission the works as quickly possible. Furthermore it is essential to coordinate [...]

  • Optimizing the Existing Interurban Road Network

    As part of the PIARC 2000-2003 work program, the Committee on Interurban Roads (C4) decided to discuss and investigate the links between the various measures available for optimising the existing interurban road network. The objective of the group is to establish the measures which work best to improve mobility, increase safety and reduce congestion on interurban roads. A questionnaire was distributed to the members and others to collect information and evaluate the available experience of the [...]

  • Environment and Construction of Road Projects

    One work area of the PIARC Committee on the Environment concerns the consequences of the construction of road projects. In July 1997, an inquiry was sent to all PIARC member countries. It dealt with the five major topics identified by the Working Group: soil and water protection; how to deal with contaminated land; recycling of used materials; how to take account of flora, fauna, archaeology, water and noise; work sites. This report contains the answers from twenty respondents and provides recommendations [...]

  • Road Safety Audits

    A Road Safety Audit is a formal systematic road safety assessment of the road or road scheme carried out by an independent, qualified auditor or team of auditors who report on the project's accident potential for all kinds of road users. Although the initial cost of the design will be a little higher, the expense of rebuilding subsequent black spots can be avoided. Accident costs can be a major component of total road costs when considering the entire economic life of a project when a significant [...]
