This text which focuses on highway related air pollution and the procedures used in the highway air quality assessment process, discusses the problems as encountered through the world, and the passage of legislation as an attempt to mitigate the problem. The major highway related pollutants are classified and their possible sources and effects are discussed. The origin and discharge of motor vehicle emissions and the characteristics of the transportation network which affect microscale and macroscale air quality are discussed, as well as the procedures for the implementation of the Clean Air Act. The collection and use of meteorological information for input into mathematical models is reviewed, and mesoscale/microscale air pollution analyses and the concept of emission factors are outlined. Further chapters discuss air pollution modeling and the input required, and procedures for establishing the background concetrations of pollutants at a specific site with emphasis on site monitoring. The definition of objectives of such a monitoring program, the planning, design and the management of the program are also covered. The requirements for air quality assessment report in an environmental impact statement are presented.
