  • Noise emitted by SKM Trains in Gdansk
    Publication

    High intensity traffic of SKM trains in Gdansk carries a significant level of noise emission. SKM line runs through the central part of the city and therefore in the vicinity of residential areas and recreational facilities. This research was planned and performed to find out what was the real noise emission of SKM trains and to determine whether the measurement noise values are within allowed limits. Individual acoustic events...

  • Pomioary hałasu drogowego
    Publication

    Ciągły rozwój motoryzacji i związanej z nią infrastruktury drogowej niesie ze sobą oprócz wielu niekwestionowanych korzyści również zagrożenia dla środowiska naturalnego i zdrowia człowieka. Obok emisji szkodliwych substancji do atmosfery jednym z najistotniejszych zagrożeń związanych z pojazdami i ruchem drogowym jest obecnie hałas. Jest on najbardziej odczuwalny w pobliżu głównych ciągów komunikacyjnych oraz przy trasach szybkiego...

  • Road texture influence on tire rolling resistance

    Tire rolling resistance is one of the most important resistive forces acting on road vehicles. It depends on tire and surface characteristics as well as vehicle operating parameters. This paper deals with the influence of road surface texture on rolling resistance of passenger car tires. Results of road measurements performed on variety of road surfaces are presented.

  • Noise Generated by Tyres Designet for Electric Vehicles - Results of Laboratory Experiments

    A few years ago, electric and hybrid vehicles were rarely seen on public roads and were considered more as exotic curiosities or even as a sign of extravagance than a practical means of transport. Nowadays the situation has changes significantly. This was caused both by the technical development and legislative actions, as well as the organizational nature promoting the purchace and use of low emission vehicles. Electric vehicles...

  • Reduction of noise and rolling resistance by horizontal grinding of asphalt pavements
    Publication

    - Year 2015

    Grinding of cement concrete pavements to reduce unevenness and noise is common since a long time. Grinding is then made with wheels equipped with diamond blades rotating in the vertical plane. This creates narrow vertical/longitudinal grooves in the pavement. It is not applied to asphalt pavements. In this paper an alternative type of grinding is studied. In this case plates with diamond heads rotate in the same plane as the pavement,...

  • Speed dependency of temperature effects on road traffic noise
    Publication

    - Year 2015

    Recently, a new literature review on the influence of temperature on tire/road noise became available, based on a compilation of large amounts of data from empirical research. This review showed that the effect of temperature is roughly double of that previously assumed and taken account of in international standards. This makes temperature one of the main sources of error in measurement results. Furthermore, it suggested that...

  • Temperature influence on tire/road noise evaluated by the drum method

    Ambient air and road surface temperatures substantially affect the road vehicle noise emission. The temperature influence on tire/road noise depends mainly on tire-road combination. It is different for dense and porous pavements, for bituminous and cement ones. It differs also depending on tires. The correction procedures for temperature effect are still under consideration and preparation. Laboratory experiment was prepared to...

  • noise map validation by continuous noise monitoring
    Publication

    Artykuł dotyczy porównania dwóch rodzajów oceny hałasu w aglomeracjigdańskiej. Pierwsza ocena została przygotowana na podstawie prognozy hałasu w oparciu o mapy stworzone metodami obliczeniowymi w roku 2007. Druga ocena bazuje na rzeczywistych danych pomiarowych zarejestrowanych przez system ciągłego monitoringu działającego w aglomeracji od 2008 roku. W artykule zaprezentowano i przeprowadzono analizy występujących różnic pomiędzy...

  • Noise measurements on low noise pavements - problems with inhomogeneity of wearing course
    Publication

    - Year 2013

    During the last several years, when performing numerous CPX noise measurements on low noise pavements,significant inhomogeneity of the wearing course was observed in numerous cases. Similar problems were almost not existing regarding to the dense pavements.In general three main reasons of inhomogeneity can be defined. The first one are imperfections in technology of production of a asphalt mix or/and errors made already during...

  • PRZEDELĄD HAŁAŚLIWOŚCI NAWIERZCHNI DROGOWYCH W POLSCE I W INNYCH KRAJACH UNII EUROPEJSKIEJ
    Publication

    - Year 2013

    W pracy przedstawiono szczegółowo dwiemetody badania hałaśliwości nawierzchni drogowych (SPB i CPX) i zaprezentowano wyniki pomiarów przeprowadzonych metodą CPX na nawierzchniach drogowych na przestrzeni ostatnich 14 lat. Pomiary przeprowadzono na 154 odcinkach zlokalizowanych na terenie Polski oraz na 419 odcinkach na terenie innych państw europejskich. Dokonano oceny hałaśliwości warstw scieralnych występujących w naszym kraju...

  • Nowoczesne urządzenia do badania tekstury nawierzchni drogowej
    Publication

    - Year 2004

    Dokonano przeglądu urządzeń do badania tekstury nawierzchni drogowej różnymi metodami. Opisano urządzenia dawniej stosowane (badania metodą wolumetryczną oraz metodą wypływu cieczy), natomiast szerzej przedstawiono nowoczesne metody badań metodą profilometryczną. Zaprezentowano także nowoczesne urządzenia trójwymiarowe do pomiaru tekstury - system T3D. Przeanalizowano wady i zalety poszczególnych urządzeń do różnych zastosowań.

  • Pavement ageing influence on tyre/road noise
    Publication

    - Year 2017

    Road surface should be constructed in a way that ensures safe and comfortable traffic conditions, not only when it is newly paved but also during its entire lifetime. An important factor in the asphalt mixture design process is also the expected pavement durability and stability of pavement properties over time. In many countries, road surface starts to play a significant role in traffic noise reduction actions. Selecting a particular...

  • Reduction of road traffic noise by source measures — present and future strategies

    The current trend worldwide is less focused on reducing road traffic noise. This is in strong contrast to the severe impact of traffic noise to the general health and quality of life. A more holistic and combined strategy is needed. Current international rules and regulations regarding vehicles and tyres are not sufficient to reduce traffic noise levels in an effective way. Calculations show that these regulations will only yield...

  • Poroelastic Road Surface – a Promising Road Traffic Noise Abatement Solution
    Publication

    - Year 2018

    Road surfaces have a direct impact on the generation of noise by rolling tyres, the main and dominant source of noise of moving vehicles, as well as may affect propagation of noise emitted by all noise sources of a vehicle. Thus there is no doubt that pavement should be considered as one of the major potential road traffic noise abatement measure. Low noise pavements of existing types may in new conditions provide up to 8 dB of...

    Publication

    - Year 2023

    Within the Polish-Norwegian research project ELANORE, a limited Round Robin Test has been performed on four ISO tracks in Northern Europe. The basic objective of the project is to improve the EU directive on labelling of tyres for noise and rolling resistance. This directive is based on the measurement procedures proscribed in the UNECE Reg.117. Measurements on 3 ISO tracks were performed in 2021 and presented at InterNoise 2022....
