Abstract
HSR uses road shoulders to improve congestion, butreducing the lateral width to obstructions when the shoulder is a travel lane creates the perception of compromised safety. Few HSR projects have existed long enough to compare safety data to determine if this is a legitimate concern. This presentation will compare the crash trends before and after the implementation of Ohio’s first HSR project and discuss gaps in the current practice.

HSR uses road shoulders to improve congestion, butreducing the lateral width to obstructions when the shoulder is a travel lane creates the perception of compromised safety. Few HSR projects have existed long enough to compare safety data to determine if this is a legitimate concern. This presentation will compare the crash trends before and after the implementation of Ohio’s first HSR project and discuss gaps in the current practice.
