ANALYSES, EXPERIMENTAL STUDIES, AND EVALUATIONS OF CONTROL MEASURES FOR AIR FLOW AND AIR QUALITY ON AND NEAR HIGHWAYS; VOLUME II--USER GUIDELINES AND APPLICATIONS NOTES FOR ESTIMATING AIR QUALITY FOR ALTERNATIVE ROADWAY CONFIGURATIONS

A manual user-oriented methodology has been developed for estimating air quality conditions at each of a wide variety of simple and complex roadway configurations. Guidelines are presented in four parts for the evaluation of air quality conditions at alternative roadway configurations. The first part presents a background discussion of principles of atmospheric dispersion and the emission of pollution (particularly carbon monoxide) by motor vehicles. In the second part the theory and application of the dispersion methodology is presented; the procedure is based on the roadway-atmospheric dispersion model of air pollution (ROADMAP) developed in Volume I of this report. To aid the user in applying the methodology, a worksheet format is used with accompanying tables and graphs. The applications of the methodology to some thirty site configurations in part three is intended to demonstrate the various tactical uses of the guidelines. The fourth part, on the other hand, presents some of the strategic considerations and limitations pertinent to the proper application of the guidelines for the purpose of air quality management. In addition to the two-volume final report, two other reports and a movie dealing with various aspects of this study are available. The Executive Summary (FHWA/RD-81/053) presents the overall scope and the important technical results of the study. A user's manual for the experimental data collected in the field and wind tunnel tests is also available (FHWA/RD-81/054). The 20-minute 16-mm color movie, "Highway Pollution Dispersion: Air Quality in the Right-of-Way," uses sound, animation, graphics, and film sequences to present a comprehensive introduction to the causes and characteristics of microscale pollution dispersion near highways.
