4. 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 –Consistent estimates of traffic flow for every link in its network –Average speeds and %HGVs (by time period) for each link –Data easily transferred on to GIS packages –Ability to forecast future traffic conditions and the impacts of any traffic- related interventions –Minor roads and low-flow residential streets not included in TMfS (so flows on these estimated separately) Annualisation factors are used to convert AM Peak, Inter- Peak & PM Peak traffic estimates to 18-hr flows.

7. Geo-rectification of TMfS We developed a method to match the model network “stick” links to OS Master Map ITN features. This ensured that the traffic information is positioned consistently with other noise mapping data TMfS ITN © Crown copyright. All rights reserved Scottish Executive 100020540 2007

8. 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

9. Agglomerations and Major Routes  the Edinburgh agglomeration;  the Glasgow agglomeration;  the entire Scottish motorway network (M8, M9, M74, M77, M80, M90 and M876);  the A1 from the Edinburgh agglomeration boundary to Haddington;  the A9 (Stirling to Perth);  the A77 from the M77 to Ayr;  the A78 from the A77 to Greenock;  the A82 from the M8 to Dumbarton;  the A90 from Perth to Aberdeen (via Dundee);  the A92 (Halbeath to Glenrothes); and  the A96 (Aberdeen to Inverurie). NB The high-flow section of the A737 between Johnstone and Glasgow will be covered by the Glasgow agglomeration mapping

29. 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.
