• Abstract:
  The main objective of this study was to assess the feasibility and effectiveness of transparent lightweight noise barriers on IH-30 in Dallas, and to serve as a pilot project for TxDOT for future similar projects. An opportunity to implement similar research and extend the project arose with the noise study on SH 190. The research team undertook these activities: • Conducted a feasibility study for lightweight traffic noise walls. • Selected barrier material types and vendors. • Performed the noise modeling and the acoustical design of the barriers. • Performed sound measurements before and after the barriers’ installation. • Conducted periodic inspections of the barriers condition. • Analyzed noise measurements and evaluated the walls’ performance.
