  • COVID-19: initial impacts and responses to the pandemic from road and transport agencies

    The road transport sector, and the organisations and professionals who manage it, is an essential service and PIARC recognized the potential for COVID-19 to cause severe disruption to the road transport sector early on. In mid-March 2020, PIARC moved to establish a formal PIARC COVID-19 Response Team to explore the rapid sharing of knowledge and practice between PIARC members in terms of pandemic impacts, associated economic and social crisis and the relevant responses. Activities were rapidly launched [...]

  • Ex-Post Evaluation of Road Projects

    Effective planning and policy development depend, in part, on the availability of suitable models for predicting the effects of project alternatives, and on an understanding of model limitations. A Swedish case study illustrates how the predictive models can be improved by incorporating the lessons from ex post evaluation. The evaluation of the Stockholm experience also found that the modeling traffic and travel times within a static equilibrium framework led to under-prediction of travel time savings, [...]

  • Approaches to evaluation of social impacts of road projects

    This report reviews the approaches used to evaluate social impacts associated with the development and use of roads, at the project level. After an analysis of the limits of traditional project assessments, the report reflects the diversity of the perception of social impacts in different countries. The core of the report is a critical presentation of the approaches used in social impact assessment: overview of systematic approaches for the ex-ante evaluations; practices of international financial [...]

  • Pricing as a tool for funding and regulation in an equity's perspective

    Traditionally, instruments such as taxes, charges and tolls have been used for funding infrastructure construction and maintenance. In recent years, pricing has been used for regulatory purposes as a measure against congestion, for mitigating environmental impacts; and for safety improvement. The question whether road pricing could be a useful instrument and in which way it should be applied can only be sufficiently answered after clearly defining the objectives of the instrument. Does the priority [...]

  • The use of monetised values for socio-environmental impacts of road projects

    This report presents the current practice of monetising socio/environmental impacts in road project appraisal methodologies. It presents: a synthesis of the responses from 13 countries to an international survey; an overview of the HEATCO study on road project appraisal techniques across 25 countries of the European Union; and compares the findings of this last study with practice in Japan, Australia/New Zealand and on the American continent. The report shows no consistency among the methodologies [...]
