Topic 35. Air pollution and noise measurement, assessment and mitigation measures

  • IP0403 - Assessment of Surface Texture on Road Safety
    Emine Nazan ÜNAL

    The surface texture structure significantly affects pavement skid resistance and tyre/road noise. Skid resistance is an important safety factor for highway pavement. An appropriate level of skid resistance reduces vehicle operation cost, traffic accidents, and fatalities, particularly in wet conditions. And also, traffic noise, which is steadily increasing, is considered to be an important environmental [...]

  • IP0258 - Change and evaluation of road surface noise
    Vítězslav KŘIVÁNEK

    Road pavement variable parameters include surface noise. This parameter is monitored by the CPX method on various types of road surfaces in the Czech Republic as low-noise pavements, asphalt surfaces with different maximum aggregate sizes, or concrete pavements with various surface treatments. The intention is to use the measured and analysed data to determine of classification levels for assessment [...]

  • IP0242 - CNOSSOS-EU – System for determining the national coefficients of noise emission of road surfaces in the Czech Republic
    Martin LÁDYŠ

    The CNOSSOS-EU road traffic noise calculation methodology is an international approach, yet it contains a number of factors characterizing the national noise-emission-affecting specifics, e.g. vehicle fleet or mostly used surfaces. That is why a number of countries are trying to implement some of their own corrections in order to refine acoustic calculations in their territories. The project is [...]

  • IP0529 - Differences in the results of road noise calculations made using different models used in European countries
    Maciej HAŁUCHA

    Acoustic models used for noise calculations are characterized by specific algorithms that differ from one another. This affects the results of modeling, which could be clearly observed by analyzing the results of strategic noise maps made in the past using different methods specific to different EU countries. These differences were one of the reasons for starting work on a common European noise model [...]

  • IP0342 - Double-layer porous asphalt – Performance of innovative noise-reducing variants

    Since 2010 double-layer porous asphalt (DPA) pavements have been used on motorway E4 through the Swedish city Huskvarna. The pavement has been a great success despite the challenge to use porous pavements in a country where studded tyres are used in wintertime, resulting in excessive surface wear and subsequent clogging of pores. In this paper, seven interesting trials on this road related to the [...]

  • IP0749 - ECO-ROADS PROJECT: innovative barriers for mitigation of noise and chemical pollution from roads

    ECOROADS is a project funded under the PON Research and Innovation Action 2014-2020, dealing with the development of technologies and systems for decarbonisation, energy efficiency and environmental sustainability of road transport. To that end, the project aims to test the effectiveness of air pollution mitigation techniques through the introduction into controlled environments of woody species and [...]

  • IP0757 - Italian PIARC TC 3.4.2: Effectiveness and Sustainability of Noise Mitigation Measures
    Patrizia BELLUCCI

    Road traffic is the primary source of noise pollution in Europe, with noise levels projected to rise in urban and rural areas over the next decade due to urban growth and increased demand for mobility. Despite the EU recommends avoiding long-term exposure to noise levels greater than 55 decibels – dB(A) – it is estimated that in most European countries, more than 50 % of inhabitants within urban [...]

  • IP0161 - Low-noise road surface adjustments and general traffic noise reduction
    Lukas TOPINKA

    One of the most important variables affecting traffic safety is the skid resistance of the road. However, as the value of the longitudinal friction coefficient increases, so the noise pollution generated at the tyre-road interface also increases. Noise pollution, together with air pollution from car emissions, has been a major media and political issue in recent years, and public authorities demand [...]

  • IP0667 - New perspectives on the LIFE DYNAMAP project

    Born in 2014 and ended in 2019, the LIFE DYNAMAP project aimed at developing a dynamic noise mapping system able to detect and represent in real time the acoustic impact of road infrastructures. Scope of the project was the Directive 2002/49/EC (END) of the European Parliament and the Council, which requires Member States to provide noise maps every five years to report changes in environmental conditions [...]

  • IP0200 - Pilot project of active road noise reduction through speed limit regulation

    The aim of the project was to design, develop, build and practically test a new system of active road noise reduction through speed limit regulation. The system uses technology mounted on traffic management portals to collect data straight above the road surface. In the real time, the system monitors current meteorology, collects acoustic data (sound pressure levels, frequency spectrum), counts and [...]

  • IP0241 - Silent Tunnels
    Ondřej SIMON

    Noise emitted by traffic tunnels mouths near protected buildings is a problem for both existing and newly designed projects. The behavior and influence of this acoustic phenomena isn’t widely published, although this effect is marginally taken into account within tunnel projects worldwide. Detailed research of the tunnel portals acoustic energy propagation, as well as a new acoustic cladding system [...]

  • IP0752 - The assessment of noise through the recognition of pavement surface characteristics
    Enea Guido SOGNO

    Constant monitoring of road pavements is a fundamental action, first of all to assess their level of degradation and, consequently, to be able to plan the necessary maintenance over time based also on objective, technical information in order to prevent accidents. The most representative parameters of the functional characteristics of the pavement, thanks to the continuous technological progress [...]

  • IP0656 - Traffic management schemes to reduce air and noise pollution
    Tina ONORATO

    Transport accounts for around a fifth of GHG emissions in Europe and for a large share of urban air pollution, including relevant emissions of nitrogen dioxide and particulate matter, as well as noise nuisance that causes serious effects on human health, ecosystems and the environment. On the way to the 2050 goal set by the Green Deal to counteract the effects of pollution, the European Commission [...]
