  • Measuring Road Traffic Noise

    As part of an overall measurement programme to monitor road traffic noise in Århus (Denmarks second largest city), the Local Authority set up a noise measurement station on one of the major approach roads to Århus Harbour. This noise measurement station continually measures noise levels and can give a round-the-clock picture of noise level variations. Like most other districts, Århus Local ...

  • Canarina CUSTIC software · noise calculation · algorithms 3

    In a road case, we shall consider several points.  We shall consider a minimum number of 1000 vehicles per hour N with a 50km/h minimum velocity (100km/h is the maximum velocity). Then we have a 68 dB(A) noise level at 10m from a lineal road (infinity length). The noise level will be,   ...

    1 Guidebook Introduction 1.1 Introduction The joint EMEP (1)/EEA Air Pollutant Emission Inventory Guidebook (the 'Guidebook'), following the 'Guidelines for Reporting Emissions and Projections Data' under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP) (2), provides concise guidance on how ...

  • Studying street geometry influence in PM10 concentration

    This paper intends to show the influence of street geometry in particle concentration emitted from traffic source, on a busy street of Barreiro City, Portugal. FLUENT software was used to simulate particle dispersion, air flow and turbulence in the street. Buildings and road characteristics were considered, as well as winter and summer most predominant meteorological conditions. Also, particle ...
