Sample Methodologies for Regional Emissions Analysis in Small Urban and Rural Areas

In This Article:

Many small urban and isolated rural nonattainment and maintenance areas face challenges in conducting the regional emissions analysis that is the key analytic component of the transportation conformity process. Small urban and rural areas typically have limited data and often lack the necessary network-based travel demand forecasting models. The Federal Highway Administration (FHWA) commissioned this study to help small urban and rural areas gain a better understanding of several options for conducting regional emissions analysis. It provides information on sample methodologies and adjustment techniques that have been used for regional emissions analysis in a number of small urban and isolated rural nonattainment and maintenance areas.
