INSPIRE Strategic noise maps. Noise contour map for railway noise in agglomerations – Lden

Catagóir: Environment
Tuairimí: 17
Rátáil oscailteachta:

This is a polygon dataset of the strategic noise mapping of rail, which were identified as those rail exceeding the flow threshold of 30,000 vehicle 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.

Eolas Dualfhoinse The strategic noise mapping of the major heavy rail network across Ireland was undertaken by the Irish Rail, with support from the Railway Procurement Agency (RPA) who are responsible for mapping noise emissions associated with operational Luas light rail lines in Dublin. They provide supplementary information relating to the Noise Action Plans developed in 2013 for the major rail network in Ireland as part of the second round of the implementation of the EC Directive 2002/49/EC. The Directive was transposed in Ireland as Statutory Instrument, S.I. 140 of 2006, Environmental Noise Regulation 2006. Major Rail is classified as the network extent where rail traffic exceeds 30,000 vehicle passages per year. The Irish Rail Working Timetable was used to determine the traffic on the rail network for 2011. This Working Timetable includes for all scheduled train movements on the rail network, including revenue and non-revenue movements (i.e. passenger trains, freight trains, empty trains and other non-passenger trains). Irish Rail prepared a report detailing the extent of noise mapping for Round 2 for the Irish Rail heavy rail network. The report demonstrated the following: • Owning to the reduction of the Major Rail threshold to 30,000 vehicle passages per year the majority of rail in the Dublin Agglomeration area is classified as Major Rail in 2011. Therefore, for the Round 2 Strategic Noise Mapping it was considered appropriate to utilise the Round 1 ‘All Rail’ dataset to represent the Round 2 ‘Major Rail’ in the Dublin Agglomeration Area. • The train passage numbers within the Cork Agglomeration Area are below the rail traffic threshold for Major Rail. • The only section of Major Rail, outside of the Dublin Agglomeration Area, is a 36km stretch on the Dublin to Cork mainline, extending out of the Dublin Agglomeration Area to Cherryville Junction. The Luas Red Line links Tallaght with Connolly Station and went into public service in September 2004. Since December 2009, Luas Docklands, the extension of the Luas Red Line to The Point commenced passenger services. The line serves the IFSC and the area east of the Royal Canal. Luas Citywest is the extension of the Luas Red Line (Connolly to Tallaght) to Citywest and Saggart. Red Line services pass through the administrative areas of Dublin City Council (DCC) and South Dublin County Council (SDCC). The Luas Green Line, which extends from Sandyford to St. Stephen’s Green, went into public service in June 2004. Luas Cherrywood commenced services in 2010 and extends the existing Luas Green Line (St. Stephen’s Green to Sandyford) to Cherrywood and Bride’s Glen. Green Line services pass through the administrative areas of DCC and Dún Laoghaire-Rathdown County Council (DLRCC). The extent of the Luas railway source incorporated in mapping was 39km in length.
