Noise Barrier

The completion of the largest Ohio Department of Transportation traffic noise abatement project in 1995 was met with public controversy over the effectiveness of the noise barriers. A public opinion survey was designed to obtain the perceptions of the residents in the project area. In a departure from most surveys of traffic noise barrier effectiveness, the coverage was not limited to the first or second row of houses, but was extended to 800 m on each side of the roadway. It was found that the larger survey area was needed to avoid misleading conclusions. Overall perceptions of noise barrier effectiveness were found to vary with distance from the roadway and with noise barrier configuration.

Noise Barrier

This paper presents the results of a statewide noise barrier study for the New Hampshire Department of Transportation (NHDOT). The feasibility and reasonableness of noise barriers throughout the state has been evaluated according to NHDOT acoustical and cost-effectiveness criteria. The study has provided the DOT with an estimate of the potential noise barrier material costs associated with a newly implemented Type II noise barrier program. The study also has identified municipalities that the DOT can coordinate with for enacting noise-compatible planning regulations. The paper describes the methodology used to develop the screening-level noise barrier evaluation. Highway noise levels throughout the state and the distances from the highway where noise levels exceed the noise abatement criteria were determined. A method to predict the noise reduction of barriers (insertion loss) based on a simple geometrical relationship of receptors and potential noise barriers was established and has been shown to correlate well to detailed traffic noise models using actual roadway and terrain geometry. The simplified prediction method was used to evaluate over 300 miles of highway, 300 candidate noise barrier study areas, and over 30,000 receptors. This screening-level modeling approach is critical to the practicality of using the Traffic Noise Model across the entire state given the significant number of receptors and noise barrier study areas. The results of the study including information about all 30,000 receptors and 300 noise barrier study areas were collected in Google Earth™ data files for easy access when the DOT responds to noise complaints from the public.

Many recent empirical analyses of citizens' issue attitudes rely on the seven-point issue scales, which have been included in all of the biennial National Election Studies (NES) since 1968. The question format used to create these scales requires people to respond to two different issue statements simultaneously. While this approach has a number of practical advantages, it may also distort the measurement of issue attitudes in several ways. In order to examine this possibility, a 1990 South Carolina public-opinion survey had people respond to the separate issue statements. The empirical results lead to an optimistic assessment of the seven-point scales. People do seem to regard the paired issue statements in any of the seven-point questions as the opposite sides of a political controversy. This general conclusion has some important caveats: there are several distinct dimensions underlying citizens' issue judgments, and the degree of psychological distance between conflicting issue positions varies somewhat across issues. These findings have important implications for our understanding and measurement of citizens' issue attitudes.
