FHWA’s Innovative New Traffic Noise Model Applications
Presentation Outline
• Background
• Challenges
• Solution Overview
• Project Approach
• TNM 3.0 Capabilities
• Lessons Learned
• Next Steps
Background - What is Traffic Noise Modeling
• Theory behind noise modeling in general
• Applications to traffic
Background - What is Traffic Noise Modeling
Noise Control Act of 1972 issued by EPA
Background - FWHA’s Role and Responsibilities
How long FHWA and State DOT have been overseeing traffic noise modeling
Background - TNM for Highway Design Projects
Background - Legacy TNM Software History
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
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
Challenges - Technical
• Limitations of TNM 2.5
• Deployment/Licensing challenges
• New user requirements (enhanced 3D, snapping, etc.)

Lessons Learned - Technical
• Roadmap – transition Cesium to Esri Javascript API 4.0
• Project data structures – one composite vs separate
• 3rd party toolset for section visualization
Lessons Learned - Operational
• Teaching new processes are different and better
• Need for pre-beta testing education/training on new methods to complete old workflows
• Need for improving model calculation speeds
• Redundant object attribute editing options
• Increase number and variety of online help workflow examples
Next Steps
• Performance Optimization
• UI improvements based on beta tester feedback
• Marketing and Training Campaign
