NCHRP Project 15-34: Performance-Based Analysis of Geometric Design of Highways and Streets

This research project will culminate in a guidebook for conducting performance-based geometric design. Initially, the guidebook will articulate a vision for performance-based analysis of geometric design of highways, and subsequently provide information about the data needs, sources, and integration with specific performance measures. The guidebook will include case studies demonstrating performance-based analysis applications at each stage of project development, including data needs. This project will also recommend revisions to topics in the AASHTO publication, A Policy on Geometric Design of Highways and Streets, that are supported by the research and provide mutual support and consistency with the guide.
