The 2020 National Transportation Noise Map dataset utilized transportation mode input data from 2020 in a model and is current as of October 2022, published by the Bureau of Transportation Statistics (BTS), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Please see the website https://www.bts.gov/geospatial/national-transportation-noise-map, for downloads and more information about these datasets. For web services of these data, please navigate to https://geo.dot.gov/server/rest/services/Hosted and search for service names beginning with "Noise." Please contact j.goworowska@dot.gov for any questions. Data within the National Transportation Noise Map represent potential noise levels across the nation for an average annual day for the specified year. These data are intended to facilitate the tracking of trends in transportation-related noise by mode collectively over time and should not be used to evaluate noise levels in individual locations and/or at specific times. This dataset is developed using a 24-hr equivalent A-weighted sound level (denoted by LAeq) noise metric. The results represent the approximate average noise energy due to transportation noise sources over a 24-hour period at the receptor locations where noise is computed. Layers include Aviation, Freight and Passenger Rail, and Road Noise for the Lower 48 States as well as Alaska and Hawaii. The full listing can be found below. 2020 National Transportation Noise

Analysis of ‘Strategic noise map for the 3th road noise deadline over 24 hours Lden produced in 2011 ’ provided by Analyst-2 (analyst-2.ai), based on source dataset retrieved from http://data.europa.eu/88u/dataset/https-opendata-clermontmetropole-eu-datasets-1d7d32e188d3416f85114426bd788ed8_0 on 13 January 2022.

--- Dataset description provided by original source is as follows ---

Regulatory requirements The European Directive 2002/49/EC was transposed into French law by order and ratified by the Law of 26 October 2005 and now appears in Articles L.572-1 et seq. of the Environmental Code. Noise maps are to be developed for large transport infrastructure and large agglomerations. These maps must be made available to the public.Noise maps make it possible to draw up plans for the prevention of environmental noise (PPBE). PPBE aim to prevent noise effects, reduce noise levels where necessary and protect quiet areas. Noise maps and PPBE shall be reviewed every five years. Noise mapping method

Noise maps shall include a set of graphical representations and numerical data. They are established using the indicators Lden (day-evening night-time period) and Ln (night period) assessing noise levels. These indicators are assessed at 4 m above the ground. The calculation method is in accordance with standard NF XP S -31-133 ‘Acoustics — Land transport noise — Calculation of sound attenuation during external propagation, including meteorological effects’.

Lden (Level Day Evening Night) The value of the noise index Lden, expressed in A-weighted decibels (dB (A)), represents the total noise exposure level. It is the result of a weighted calculation taking into account the average noise levels determined over a year, for each of the three periods of the day, i.e. day (between 6h and 18h), evening (between 18h and 22h) and night (22h to 6h). The weights used to calculate the Lden index are applied over the evening and night periods in order to achieve a better representation of the discomfort perceived by residents throughout the day.

Lnight indicates night time annual average noise level results in dB, where night is defined as 2300 - 0700. Noise levels are modeled on a 10m grid at a receptor height of 4m above ground, polygons are then produced by merging neighboring cells within the following noise classes: 70.0+ dB, 65.0-69.9 dB, 60.0-64.9 dB, 55.0-59.9 dB, 50-54.9 dB, <49.9 dB This data is a product of the strategic noise mapping analysis undertaken in 2017 to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC) and the Environmental Noise (England) Regulations 2006 (as amended).

The interoperable INSPIRE Mapping Service (WMS) Health and Safety provides an overview of the isophonic maps of road traffic noise in Brandenburg according to Directive 2002/49/EC (Environmental Noise Directive). This requires the EU member states to assess and combat environmental noise. As a result, strategic noise maps had to be drawn up by June 30, 2007 as part of the first stage. These are to be revised and updated every five years. The data in question includes the 3rd stage of the EU noise mapping (2017). All municipalities in the state of Brandenburg with roads > 3 million vehicles/year were examined. As required by Section 2 of the 34th BImSchV, the two noise indices LDEN and LNight are displayed on duty. According to the INSPIRE data specification Human Health And Safety (D2.8.III.5_v3.0), the contents of the map are INSPIRE-compliant. The WMS contains the following layers: - HH.HealthDeterminantMeasure: contains isophones of road traffic noise exposure for the day (lden) and night (lnight) - HH.HealthDeterminantMeasure.MRoad.lden: contains isophones of road traffic noise exposure for the day (lden) - HH.HealthDeterminantMeasure .MRoad.lnight: contains isophones of road traffic noise pollution for the night (lnight) --- The compliant INSPIRE view service (WMS) Human Health And Safety provides an overview of the strategic noise maps for major roads in Brandenburg. According to the Directive 2002/49/EC regarding the assessment and management of environmental noise it requires the EU member states for the evaluation and abatement of noise. Therefore, strategic noise maps had to be elaborated until June 30th 2007 (1st stage). Every five years these maps have to be reevaluated and updated accordingly. The geodata refers to the third stage of the DIRECTIVE 2002/49/EC (2017). All major roads were taken into account that have a traffic volume of more than 3 million. motor vehicles per year. The content of the map is compliant to the INSPIRE data specification for the annex theme Human Health And Safety (D2.8.III.5_v3.0). The WMS includes the following layers: - HH.HealthDeterminantMeasure: contains the noise level contours of major roads during the day (lden) as well as during the night (lnight) - HH.HealthDeterminantMeasure.MRoad.lden: contains the noise level contours of major roads during the day (lden) - HH.HealthDeterminantMeasure.MRoad.lnight: contains the noise level contours of major roads during the night (lnight)

INSPIRE Strategic noise maps. Noise contour map for roads noise in agglomerations – Lden. Published by Environmental Protection Agency. Available under the license Creative Commons Attribution 4.0 (CC-BY-4.0).This is a polygon dataset of the strategic noise mapping of roads, which were identified as those roads exceeding the flow threshold of 3 million passages per year, in the form of noise contours for the Lden (day, evening, night) period for Dublin and Cork agglomerations and the major roads outside of the agglomerations. The dB value represents the average decibel value during the Lden time.

Any direct comparison of the Round 3 versus Round 2 results should be carefully considered, as changes to the model input datasets used between these rounds may be significant. This may especially apply to the terrain model used, while there may be improved building height data, & improved traffic flow data with fewer assumed flows. There may also be some revisions to the actual road network modelled in Round 3.

The noise maps are the product of assimilating a collection of digital datasets, and over the last 10 years there has been significant improvements to the quality of the digital datasets describing the natural and built environment in Ireland. This has led to the strategic noise models giving much more reliable noise results with much less tendency to over predict the impact.

UPDATE (February 2019): The Regional roads in 26 Local Authorities (LAs) outside of Dublin, and Cork have now been amended by Transport Infrastructure Ireland (TII). The original road maps had included some significant stretches of roads (~20%) that were below the 3 million vehicles movements/annum reporting threshold. These road sections have now been removed and revised Regional road maps have been released by TII.

This TII review process has resulted in an update of the National road map that is reported to the EEA. The EPA has also updated our website to reflect these changes, and we will also look to provide relevant links to the Final LA Noise Action Plans (when completed): http://www.epa.ie/monitoringassessment/noisemapping/...

Strategic noise map for road traffic with more than 3 million vehicle passes per year according to RL 2002/49/EC, together with impact of additional roads. The reference year for these data is 2016. The noise map indicates how much noise the environment is exposed to. The noise load is expressed in the parameter Lden. The Lden level is a weighted annual average sound pressure level over a 24-hour period, with the evening and night levels having relatively greater weight, which corresponds to the finding that noise pollution is generally experienced as more annoying in the evening and at night. European research shows that an Lden is a relatively good predictor of the extent to which local residents may experience nuisance. These noise maps are updated every 5 years. The strategic noise maps with reference years 2006, 2011 and 2016 were calculated using an old calculation method. From the strategic noise maps with reference year 2021, a new calculation method was used. This is a new joint European calculation method that is mandatory for all Member States from the mapping round with reference year 2021. Because this calculation method differs from that used in previous mapping rounds, it is not appropriate to compare the results of reference year 2021 with previous editions (2006, 2011 and 2016). After all, it cannot be ruled out that differences in calculated exposure are purely due to the application of this new calculation method and are not a consequence of increased or decreased exposure.
