1 FHWA s Innovative New Traffic Noise Model Applications Ahmed El-Aassar, Ph.D., P.E. Kevin Switala, GISP

2 Presentation Outline Background Challenges Solution Overview Project Approach TNM 3.0 Capabilities Lessons Learned Next Steps

3 Background - What is Traffic Noise Modeling Theory behind noise modeling in general Applications to traffic

4 Background - What is Traffic Noise Modeling Noise Control Act of 1972 issued by EPA

5 Background - FWHA s Role and Responsibilities How long FHWA and State DOT have been overseeing traffic noise modeling

6 Background - TNM for Highway Design Projects

7 Background - Legacy TNM Software History

8 Challenges - Policy Feasibility and reasonableness established in the regulation States required to establish noise reduction design goal Noise measurements required for model validation States must establish methodologies for analysis of various land uses States may implement cost averaging among common noise environments

9 Challenges - Operational Who conduct noise studies (DOTs or Consultant) How DOT s work with engineering firms Who is qualified to do noise analysis and mitigation Challenges to noise analyst - Availability of accurate CAD plans - Traffic Volume - Only DXF files

10 Challenges - Technical Limitations of TNM 2.5 Deployment/Licensing challenges New user requirements (enhanced 3D, snapping, etc.)

11 Solution Overview - Operational

12 Solution Overview - Technical Common Common Desktop Core Application Business Logic Web User Interface Services Main Application User Interface User Interface Management Services Common Components Integration Services Data Integration Services Cross Cutting Configuration Exception Handling Logging Validation Help Setup Reporting Noise Model API TNM Acoustics Library Web User Interface Application Web Services Main Application User Interface Mapping User Interface User Interface Management Services Common Components Integration Web Services Enterprise Integration Web Services ArcGIS Server Advanced Enterprise Cross Cutting Security Configuration Exception Handling Logging Validation Help Setup Reporting Data Application Database SQL Server Express External Data Enterprise Services Links to External Data and Services IIS Web Server SQL Server/Oracle based Enterprise GeoDatabase Standalone ArcGIS Desktop Extension AutoCAD Extension Microstation Extension User Interface Mapping User Interface 3D User Interface User Interface Mapping User Interface 3D User Interface User Interface Mapping User Interface 3D User Interface User Interface Mapping User Interface 3D User Interface Legend Services Host User Interface Management Services Common Components Integration Services ArcGIS Runtime Plug-in ArcGIS Runtime Host Services User Interface Management Services Common Components Integration Services ArcGIS Desktop Plug-in ArcGIS Desktop Services Host User Interface Management Services Common Components Integration Services AutoCAD Plug-in AutoCAD Host Services User Interface Management Services Common Components Integration Services Microstation Plug-in Microstation Internal Component External Component Product Internal User Interface Component External Component Wrapper Dependency Direction System, Sub-System Tier
