Abstract:

This project identified interchange configurations that account for at least 75 percent of those considered in Interchange Access Requests (IARs). The project team surveyed Federal Highway Administration (FHWA) division offices to determine the most common interchange configurations considered and constructed and the planning-level factors considered in the safety analysis. Additional questions revealed that most IARs focus on urban applications and service interchanges.
