Book Description
The scope of this project included: development of a means to quantify the service lives of materials used for construction of noise barriers in Illinois; development of a life cycle cost model for the evaluation of alternative materials; and evaluation of the need for potential changes to the Special Provisions for noise barrier construction currently used in Illinois. The project included a survey of all state departments of transportation (DOTs) to develop information on experiences with noise barrier materials and products, which showed that nationwide, less than 1% of noise barriers by length have been repaired or replaced, and that few DOTs use life cycle cost analysis for selection of noise barriers. A comprehensive list of the materials currently approved for use in Illinois by the Illinois Highway Development Council was developed. The current condition of existing Illinois noise barriers was assessed by field observation, and Illinois Department of Transportation (IDOT) maintenance personnel were surveyed to develop information on maintenance histories, costs of repairs, scheduled repair or replacement of barriers, and estimated service lives of barriers in place. Service life criteria were developed considering the structural, acoustical, and aesthetic functions of noise barriers. A life cycle cost model was developed and the relative life cycle costs of existing Illinois noise barriers were computed. Noise barrier specifications supplied by IDOT and the Illinois State Toll Highway Authority were reviewed, and recommendations for improving the organization and content of the specifications were made.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 738: Evaluating Pavement Strategies and Barriers for Noise Mitigation presents a methodology for evaluating feasibility, reasonableness, effectiveness, acoustic longevity, and economic features of pavement strategies and barriers for noise mitigation. The methodology uses a life-cycle cost analysis to examine the economic features of mitigation alternatives, the FHWA Traffic Noise Model to integrate the noise reduction performance of pavements and barriers, and on-board sound intensity measurements as an input to the prediction model. The appendixes contained in the research agency's final report provide elaborations and detail on several aspects of the research. The appendixes are not included with the print version of the report, but are available online." --Publisher description.

Book Description
The existing INDOT noise wall specification was developed primarily on the basis of knowledge of the conventional precast concrete panel systems. Currently, the constructed cost of conventional noise walls is approximately $2 million per linear mile. The noise wall is considered to be cost effective when a 5 dBA reduction can be achieved at a cost of no more than $25,000 per benefited receiver or $30,000 per benefited receiver in those cases where a majority of the receivers were in place prior to construction of the highway. In many areas, however, the above cost-effectiveness criteria are exceeded with the result that the areas are not eligible for federal-aid funding for noise abatement. Consequently, the residents in these areas are dissatisfied that no noise reduction measures are provided to them. Several alternative options may be considered by INDOT to address the above issues. The first option would be to raise the cost per receiver to make more areas eligible for noise walls. The second option would be to do nothing. The third option would be to adopt an optional line of sight (LOS) wall policy to improve customer satisfaction at a less expensive cost. Critical review was conducted on the current traffic noise policies by state DOTs nationwide, including Type II project participation, reasonableness of noise abatement, cost effectiveness of noise abatement, and third party funding. Four different types of noise barriers, including one conventional precast concrete wall and three LOS walls were installed in the study areas for field investigation. Evaluation was made on the issues relating to the construction, cost and structures of the installed noise walls, particularly the LOS walls. Recommendations were made to modify INDOT traffic noise policy and noise wall specifications.

Book Description
The objective of this study is to access and quantify the prediction means for traffic noise. Of particular interest is the noise reduction behind noise walls, referred to as the shadow zone. The study measured traffic noise at four sites in the metropolitan Chicago area with noise barriers. These four sites were modeled with both STAMINA 2.0 and FHWA Traffic Noise Model (TNM) 1.0. For these four sites, TNM predicted the observed traffic noise more accurately than STAMINA. In general, STAMINA overpredicted the traffic noise relative to the measured values. The second objective of the study was to access the state-of-the-art of top treatments for noise walls. Top treatments are an addition to a traditional noise wall to increase the effectiveness without significantly increasing the cost or height of the noise wall. It appears that top treatments are not well enough developed for consideration in Illinois at this time. The last objective was to develop a means to help educate the general public about traffic noise and noise wall characteristics. To meet this objective, two means were developed. The first was a home page that provides great flexibility due to the hypertext format. The second was a tri-fold brochure to serve as a handout at public meetings or as a visual aid for one-on-one discussions.

Book Description
This synthesis will be of interest to highway environmental engineers, noise analysts, design engineers, maintenance personnel, planners, administrators, and others responsible for the design, selection, and maintenance of noise barriers or other traffic noise abatement policies. Information is provided on current state practice associated with noise abatement techniques and on the various products that are used. This synthesis describes the state of the art with respect to traffic noise abatement procedures, especially noise barriers. This report of the Transportation Research Board provides information on the design, construction and maintenance of both new (Type I) and retrofit ( Type II) noise barriers. The design elements that are addressed include materials, the selection process, service life, foundations, drainage, aesthetics, and safety. The construction section covers technical problems related to surface effects, durability, snow damage, and costs. Other noise abatement measures such as insulation and highway design alternatives are also addressed. The issue of public demand and availability funding is included, and recommendations are made to improve the situation.
