About the talk

Horizontal road curves account for approximately 25% of fatal crashes in the U.S. while comprising only about 5% of roadway mileage. MUTCD-compliant curve warning signs with advisory speeds can reduce crashes by more than 40%, offering a cost-effective safety solution. This talk presents innovative solutions that leverage AI, low-cost smartphone and practical engineering designs to address curve safety challenges, supported by the National Science Foundation (NSF), the NCHRP Innovation Deserving Exploratory Analysis (IDEA) program, and state Departments of Transportation. In addition, recent work leveraging large-scale telematics crowdsourcing data from logistics trucking fleets across North America, combined with our innovative technology, to enable scalable roadway safety assessment and inform systemwide safety improvements will be presented.
