Effectiveness of Short Solid Barriers to Reduce Noise Generated by Different Types of Highway Vehicles

Highway noise impacts are currently abated with relatively tall concrete noise barriers, which can be costly and visually obtrusive. Shorter barriers are starting to be evaluated for noise reduction in other states. For at-grade and elevated roadways, placement of a jersey barrier at the edge of pavement instead of a traditional metal beam guard rail could reduce noise levels enough to avoid construction of a traditional taller sound barrier. The ability to effectively mitigate noise impacts using a shorter less expensive structure such as a jersey wall, could equate to significant cost savings for the Maryland Department of Transportation State Highway Administration if doing so is a viable alternative to constructing a traditional concrete noise barrier. This solution could also be effective for locations where a traditional noise barrier cannot be feasibly constructed.
