With decades of use in many other countries, the U.S. and Canada are new to the edge lane road (ELR) treatment. Despite proven safety in the U.S., discussions of ELRs are still dominated by concern and questions about the treatment. These questions center on perceived and actual safety, the new crash modification factor for ELRs, the new AASHTO guidance, traffic calming impact, etc. Little known is the safety benefit of ELRs for drivers even where no VRUs are expected – indeed, this use may save more lives than its use as a facility for vulnerable road users. Michael Williams will present on safety benefits, the regulatory status of ELRs, ongoing U.S. research, non-intuitive research findings, best practices, and future directions for the treatment.
