FHWA FY 2009 Accomplishments 6

Integrated Texture-noise Model• Task initiated in the fall of 2009 to develop a

work plan for a Texture-noise model• Collecting a sample of synchronized texture (1-D

and 2-D) and noise (OBSI) data to support an approach to define a noise prediction method using macrotexture

• Compiling a database of existing texture and noise data (accessing raw data is essential)

Source: Caltrans/UCPRC OBSI equipment
