摘要：	The project is an approach to create a more pleasing roadway environment for drivers as they pass through areas shielded by noise barrier walls by installing shadow creating fins which produce a dynamic shadow play on the wall surface. The front and back panel to post attachment system and the shadow creating fins produce a varied and more pleasing roadway environment which responds to complaints by the public about the aesthetics of current noise walls. A prototype wall 18 ft. high by 45 ft. long was built and erected and is available to planners, designer and contractors to look at in full scale. The shadow creating finds can be attached to any new concrete panel wall at an estimated cost of $10/ft. of fin ($33/m. of fin) installed. The front and back panel to post attachment system using T bolts is reliable, easy to install, provides for increased field post placement tolerances, and eliminates the need to caulk H post joints. This system (using stainless steel T bolts and channels) can be installed for an estimated additional cost of $2/sq. ft. ($21.50/sqm.) of wall. The prototype developed wall is viable and should be considered for use in limited stretches for visual relief and to highlight special locations. When used this way the prototype developed wall system could significantly improve aesthetics with little increase in the overall cost of a noise wall.
