This report presents a comparative discussion and evaluation of the modeling techniques available to assess the photochemical oxidant air quality impact of highway system modification or development. Five attributes of eight modeling techniques are discussed. The eight methods considered, in order of increasing complexity, are: (1) VMT Change, (2) Linear Rollback, (3) Nonlinear Rollback: Appendix J, (4) Gifford-Hanna Photochemical Model, (5) Statistical Relationships: Diffusion Kinetics Model, and (8) Urban Air Shed Photochemical Simulation Model. For each of these the following five attributes are discussed: (1) applicability and reliability, (2) data and manpower requirements, (3) use of the technique, (4) limitations, and (5) special features. The information presented in this report gives guidance towards choosing a model best suited to a given need, based on compatibility with these attributes.
