Abstract: The emission inventory process at commercial airports can be a time‐consuming, error‐prone, involved process. Multiple sources of varying types also complicate the process. The writers have combined all source calculations ...

Abstract: This paper presents a detailed, accurate method for assessing air pollutant emissions from airport operations for the purpose of environmental assessment. Sources may include commercial aircraft, small general aviation ...

Abstract: Highway noise control has been practiced in the United States for more than 10 years, as a result of direction provided by the Federal Highway Administration. Through 1980, more than 100 million dollars had been spent to ...

Abstract: A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically represented as points, lines ...

Abstract: Proponent mitigated development (PMD) strategies are used in the planning stages of new development to bring about compatibility between noise sensitive land uses and transportation noise. Development can be a transportation ...

Abstract: Of all the stages of expert systems construction, none is more critical than knowledge acquisition. This is particularly true in instances where domain experts such as civil engineers develop expert systems themselves, ...

Abstract: Highway noise predictive modeling has evolved dramatically in recent years. Current state‐of‐the‐art models require the extensive use of three dimensional (X,Y,Z) coordinate data to represent roadways, barriers, and ...

Abstract: One of the large analyses in this country of the need for sound absorptive treatment on highway noise barriers was conducted on the Interstate 440 project in Nashville, Tennessee. Special considerations had to be made of ...

Abstract: Long‐term construction projects have the potential to adversely affect the quality of life of residents living adjacent to the proposed activity. It is therefore desirable to quantify the relative impacts of various options ...
