EVALUATION OF AIR AND NOISE POLLUTION IMPACTS DURING THE HIGHWAY SYSTEM PLANNING STAGE

The pennsylvania Department of Transportation, in response to an increasing interest in the protection of the quality of the human environment, has undertaken the evaluation of environmental impacts during the highway system planning stage. This paper considers air and noise pollutants. The relationship between system planning and project planning is discussed, a framework for analysis is presented, and types of studies conducted by the system planning staff are defined. A macroscale study estimates the impact of an entire highway system on air quality and traffic noise levels in an urban area. A mesoscale study estimates the impact of an individual project on air quality in an urban area. Data needed to effectively evaluate air and noise pollution impacts at the system planning stage are discussed. Types of air quality models and their limitations and application to macroscale and mesoscale studies are considered. A highway noise model and its adaptation to system planning requirements and strategies for abatement of air and noise impacts are discussed.
