Transcription

1 FHWA's TNM 3.0 Status Aaron Hastings ( Aaron.Hastings@dot.gov ) U.S. DOT / RITA Volpe Center Acoustics Facility Environmental Measurement and Modeling Division

2 FHWA s Traffic Noise Model (TNM) Version 3.0 Acoustics Core acoustics Enhanced TNM objects for easier modeling Input Dialogs Improved Clarity Easier to Use Plan View Multi-lane Tool File import / export.jpg,.tif,.shp,.dxf,.dwg,.dgn Geo-referencing Report Generation 1 1

3 Acoustics Core acoustics Core algorithms remain the same Improved implementation more robust design easier to maintain Removed Poet database more transparent computations fewer limitations on data properties Enhanced TNM objects for easier modeling Roadways Mainlines highest roadway level Ramps Second highest level Shoulders Lowest level, traffic is not counted Width and Flow Control are point rather than lane specific Tree Zones have an assignable ground type 2 2

4 Input Dialogs Improved Clarity More standardized windows functionality Rows alternate between blue and white for easier reading Reorganized Tabs Added points and segments distinction in tabs Moved data fields to more appropriate tabs New Labeling in Dialogs Defaults for each dialog have their own window Easier to Use More flexible naming of points using point name extension Barrier defaults different for walls and berms Do not need to start with a wall barrier to create a berm barrier 3 3

5 Receiver Input Dialog Toggle entire column Text wrapping Resize e columns Show beginning of truncated data Full receiver name Rows alternate color Defaults get their own window 4 4

6 Roadway Input Dialog Segment specific input Point specific input Flow control available at each point More flexible traffic input 5 5

7 Barrier Input Dialog 6 6

8 Plan View Improved display of TNM objects More distinct colors, widths, shading, patterns Shading and widths can be toggled on/off Plan View toolbar Zoom to Fit, Zoom In, Zoom Out, Zoom Box Grabber Tracker Indicates length of path Legend Plan View status bar Toolbar option selected Real world coordinates 7 7

9 Plan View Shoulder and on-structure roadways Roadway width Roadway without width Zone shading Zone without shading 8 8

10 Plan View Roadway width Alternate shading color Legend 9 9

11 Multi-Lane Tool Multi-Lane Toolbar Icon Roadway or Input Line Digitizer Initialize Multi- Lane Design Tool Multi-Lane Design Tool 10 10

12 General Procedure Create a roadway or digitize an input line Roadway can be populated with desired z-coordinate data and point names Input line has z = 0 for all points and no point names Go to the Initialize Multi-Lane Design Tool dialog For existing roadway, click on the multi-lane toolbar icon ( ) For digitized input line, automatic after creation of input line Select options for lanes, shoulders, and median Go to the Multi-Lane Design Tool dialog. Enter object names Enter point names, etc and modify Z and widths as needed Build Multi-Lane Enter additional roadway data using the Roadway Input dialog 11 11

13 Initialize Multi-Lane Design Tool Number of Lanes Shoulders Traffic in Direction of Input Line Roadway Point Names Automatic Point Numbering Custom Median 12 12

14 Multi-Lane Design Tool Roadways, Shoulders, Terrain Lines, and Ground Zone Design Input Line Geometry Copy Tools Back to Initialization Create Roadways, Shoulders, Terrain Lines, and Ground Zone Quit Multi- Lane Design w/o saving 13 13

15 Gray Shoulder TNM Objects Created Black Roadway Terrain Lines for Median Cross Section Shoulder Width Roadway Width Ground Zone for Median 14 14
