Project description
This project compiled and reviewed existing road cross-section guidance (for urban, suburban, and rural environments) from across the United States, along with research findings, to identify content that would be appropriate for inclusion in Texas-based guidelines for road cross-section optimization. A separate project task focused on considering the data needs for assessing a proposed cross-section treatment, using the results from previous efforts to determine if existing guidance and data are sufficient to develop cross-section optimization guidelines. Based on the information obtained in those tasks, this report provides recommended guidelines for selecting optimal cross-sections for highways in Texas. Those guidelines include suggested revisions to the TxDOT Roadway Design Manual and Access Management Manual.
