This report provides an analysis of the ROADAPT (Roads for today, Adapted for tomorrow) and CliPDaR (Design guideline for a transnational database of downscaled Climate Projection Data for Road impact models) projects and provides concise recommendations on how to disseminate and implement the products of both projects.
This Technical Report primarily on the collection, dissemination, implementation and use of results from research and development of noise-reducing pavements from recent innovative research projects undertaken within specific CEDR member states. The report can be seen as a handbook presenting the European state of the art in the mid-2010s. The target group for this report is road engineers, planners and decision makers.
The report is to assist NRAs in the planning, building and maintaining processes of noise barriers. The first part is dedicated to the different acoustic and non-acoustic standards and guidelines used to insure performance. The second focuses on the types of barriers, looking at the aesthetic appeal, shapes and materials with a reference to the experience from the CEDR member countries. The last chapter offers a review of recent research projects on noise reducing devices.
This report presents an introduction to economical assessment methods in general and their potential role in the decision-making process of noise impact assessments or implementation of noise mitigation measures in national road administrations.
The EU Water Framework Directive (WFD) aims to protect and improve the ecological status of water bodies in order to promote sustainable watershed use. Consequently, NRAs must ensure that their water management practices meet the requirements of the WFD. This report examines; when should contaminated runoff water be treated to meet the requirements in relevant EU directives (e.g. the WFD), what is the best practice when treatment is mandatory, and what will the research needs on these matters be within the next decade?
There are numerous interventions available to road operators that can be used to reduce energy use. This situation is both positive (options are available) and negative (it is hard to select the best option). This document identifies most of the interventions currently implemented by at least one NRA together with an easily understood assessment of the economic return, environmental and safety impact, and political acceptability of these interventions.
For NRAs, it is important to recognise changes in time in order to reduce greenhouse gas emissions and provide more resilience for existing and proposed roads. Acting on climate change is not a unified topic for road owners; both mitigation and adaptation to climate change are different sub-topics. Despite the dissimilarities, adaptation and mitigation share the need for long-term planning for an uncertain but undoubtedly different future. Both topics are, therefore, presented in this report.
At the start of the CEDR RN2 work programme, it was identified that the noise mapping and action planning requirements of the EU Environmental Noise Directive (END) would form a significant component of the group's activities. Five subgroups were established to review and monitor activities associated with END noise mapping, END action planning, value for money in road traffic noise abatement, the EU noise calculation model (CNOSSOS-EU), and road noise research needs.
The latest innovative research in the areas of noise reducing pavements, noise barriers, and
cost-benefit analysis (CBA)/cost-effectiveness analysis (CEA) was comprehensively reviewed
and assessed by CEDR Task Group I6 (Road Noise).
