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

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

3. 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

4. POTENTAIL ABUSE OF STRATEGIC MAPS PAN 56?

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

8. 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

9. Building Footprints – Source
OS MasterMap
General best quality data for UK. All data polygonised and richer attribute set than previous data (landline)

10. 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.

11. 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).

12. 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.

13. 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.

14. 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':

15. 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).

16. 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.

17. 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.

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

19. 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.

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

22. 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

23. 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

24. TMfS Network Detail and Flow Estimates

25. 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

Scottish END|6 October 2006

26. 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

27. END Major Road Sections
“red” sections show flows > 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

28. 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.
