Safety Evaluation of Diverging Diamond Interchanges in Missouri
Presented by Boris Claros and Henry Brown from the University of Missouri - Columbia
The Diverging Diamond Interchange (DDI) has gained in popularity in the United States during the last decade. The operational benefits and lower costs of retrofitting a conventional diamond with a DDI have contributed to its increased use. Existing research on DDIs has focused primarily on the assessment of operational benefits. Unfortunately, formal safety evaluations of DDIs are lacking. This study filled the knowledge gap by conducting a safety evaluation at the project-level (interchange) and the site-specific level (ramp terminals) of DDIs using three types of before-after evaluation methods.
Join us for this presentation to learn about these methods and the results of the study.
