Noise Mapping For The Environmental Noise Directive WHAT IT MEANS FOR SCOTLAND Dr Bernadette McKell, October 2006

EU Directive 2002/49/EC The Environmental Noise (Scotland) Regulations 2006 Intended to “inform the public about environmental noise and its effects”

Produce strategic and strategic consolidated noise maps for large urban areas (agglomerations) major roads (6 million vehicle threshold) major railways (more than 60,000 train passages per year ) major airports (more than 50,000 movements per year) Produce action plans to manage and reduce environmental noise where necessary preserving environmental noise quality where it is good

Noise Mapping For The Environmental Noise Directive An Automated Methodology For the Identification of Industrial Noise Sources

Overview END Requirements onerous No comprehensive data source available Automated method essential for first round of mapping Making use of publicly available data Resultant data can be refined

Building Footprints – Source OS MasterMap General best quality data for UK. All data polygonised and richer attribute set than previous data (landline) © Crown Copyright. All rights reserved Scottish Executive 100020540 2005.

Building Footprints – Base Data OS MasterMap – building footprints extracted Every building in area extracted, including huts, garages etc. This is the base for all of the inferred and detailed building type assignments. © Crown Copyright. All rights reserved Scottish Executive 100020540 2005.

Inferred Use – Level 1 OS AddressPoint Data – Inferred Building Use AddressPoint data – inferred classification. If an address has does not have an organisation associated with it is assumed to be RESIDENTIAL, otherwise a word search is carried out through the organisation name field to interpret the type of use. Default is COMIND (others are AMENITY/RECREATION, EDUCATION, FARM, HEALTH,RELIGIOUS). © Crown Copyright. All rights reserved Scottish Executive 100020540 2005.

Building Footprints – Level 1 Building Footprints with AddressPoint Inferred uses Building fooprints updated with the values from the inferred uses from AddressPoint – any buildings without an AddressPoint are recorded as ‘Not classified’. It is recognised that this method is not comprehensive and will have an inbuilt error – but it is a good starting point and can be used where more detailed information is currently not available. © Crown Copyright. All rights reserved Scottish Executive 100020540 2005.

Inferred Use – Level 2 Standardised (national) land use classes from Local Plans Standardised land use classes for the whole of UK captured by Landmark Information Group. These include all classes from each Local Authority Local Plan. This is intended to allow us to sweep up those buildings which do not have an address but nevertheless have an industrial use – e.g. large works where only the office is addressable. © Landmark and/or its Data Suppliers 2005 (Data kindly supplied by Landmark for evaluation purposes).

Inferred Use – Level 2 Land use constraints polygons which indicate uses likely to produce industrial noise We went through the 79 classes and assigned the to Airport, commercial, heavy, ports (with ports having precedence). Classes correspond to the default values for Sound Power Levels Unknown - Tool 5 – in the 'Good Practice Guide for Strategic Noise Mapping and the Production of Associated Data on Noise Exposure': © Landmark and/or its Data Suppliers 2005 (Data kindly supplied by Landmark for evaluation purposes).

Building Footprints – Level 2 Building footprints assigned to land use constraints polygons which indicate uses likely to produce industrial noise. Class values applied to the building footprints. © Landmark and/or its Data Suppliers 2005 (Data kindly supplied by Landmark for evaluation purposes).

Inferred Use – Level 3 Building footprints assigned to PointX classification (as assessed by SEPA for likelihood to produce industrial noise). This is the most detailed level of classification. PointX data with 323 classes assigned the default values for Sound Power Levels Unknown - Tool 5 – in the 'Good Practice Guide for Strategic Noise Mapping and the Production of Associated Data on Noise Exposure‘ by SEPA. These were then applied to PointX data, and the PointX data to the building footprints. Only data with one of the noise classes were applied to the buildings – and only some buildings have an association. This is not a comprehensive dataset and is constantly being updated. Anomalies will include an arbitrary shop being applied to a shopping centre etc. © Crown Copyright.

Inferred Use – Final Use Sources: Building Footprints (AddressPoint inferred classification) - inferred value Building Footprints (Land Use classification) – update inferred uses where building not addressable Building Footprints (PointX and SEPA Noise Level Classes) – accurate, but limited, individual building classes Detailed Assignment: PointX is assumed to be the most accurate information, and if a building contains a point then this is taken as the building type (based on the SEPA assigned classification of the data). Where no building type is available from PointX, the value assigned using the land use polygons is then used. Where neither are available, the inferred use is used. Any occurrence in inferred use of Commercial/Industrial, not previously assigned using the other datasets, has been assigned to Light.

Building footprints – Final Use Building footprints assigned to finalised building classification using methodology described. Combination of all classifications based on the methodology © Crown Copyright.

Inferred Use – Final Use Classes Industrial Uses based on Sound Power Levels Unknown, 'Good Practice Guide for Strategic Noise Mapping and the Production of Associated Data on Noise Exposure': Airport - to be dealt with by the Airport Authority Commercial - corresponds to Area with commercial uses Heavy- corresponds to Area with heavy industries Light- corresponds to Area with light industries Ports - corresponds to Ports Other Uses: Amenity/Recreation Education Farm Health Religious Residential Not classified - garden huts, garages etc.

Scottish European Noise Directive Traffic Flow Estimates for Noise Mapping Dr David Connolly | 6 October 2006

Transport Model for Scotland (TMfS) TMfS is a transport and Land Use modelling tool and database that enables the Scottish Executive and Local Authorities to assess major inter-urban road and public transport schemes and major transport policy options. TMfS currently covers 95% of Scotland’s population Scottish END|6 October 2006

Traffic Data for Noise Mapping TMfS provides: Week-day AM Peak, Inter-Peak & PM Peak traffic estimates for most of the relevant roads in the required areas Average speeds and %HGVs (by time period) for every link Ability to forecast future traffic conditions and the impacts of any traffic-related interventions Data easily transferred on to GIS packages Annualisation factors will be used to convert AM Peak, Inter-Peak & PM Peak traffic estimates to 18-hr flows. Scottish END|6 October 2006

TMfS Network Detail and Flow Estimates

Geo-rectification of TMfS We are developing a method to match the model network “stick” links to OS Master Map ITN features. This will ensure that the traffic information is positioned consistently with other noise mapping data TMfS ITN Scottish END|6 October 2006

Geo-rectification of TMfS The geo-rectification method combines manual adjustments and automated processes to ensure a good quality correspondence. The key processes are: Node Matching Link Matching Dual Carriageway processing Roundabout processing Complex junction processing Scottish END|6 October 2006

END Major Road Sections “red” sections show flows > 16000 AAWDT based on traffic counts Included in first round of END mapping Being reviewed against TMfS data Some short “outlier” sections may be included in second round of mapping

Other Road Attributes In addition to integrating the traffic model data, the END network has to manage other attributes, eg: pavement type road gradient location of bridges and culverts These attributes lie along a partial edge or may cross several edges without changing characteristic. In these cases we will employ “dynamic segmentation”, which is a GIS technique to reference attributes to lengths of road. This method is already used within the SERIS database.
