摘要：	The Iowa Department of Transportation routinely assesses the potential traffic impact of highway bypasses on small cities in the State. For a given city, this labor-intensive process may take from one-to-three person months to complete. With the implementation of Iowa's Commercial and Industrial Network, bypass analyses are becoming more frequent, and are now required for six-to-eight cities per year, placing a strain on limited planning staff resources. This paper describes a GIS-based modeling approach which can streamline and automate the process, thereby reducing resource requirements or increasing the number of studies that can be completed within a given time. The automated process also serves to promote consistency across projects. This paper also validates the new approach by comparing manual-based estimates of impact to those predicted by the new methodology.
