Safety Performance of Part-Time Shoulder Use on Freeways, Volume 2: Conduct of Research Report
Part-time shoulder use (PTSU) is a congestion relief strategy that allows use of the left or right shoulders as travel lanes during some, but not all, hours of the day. PTSU operation in the United States (US) has been exclusively on freeways, and findings presented in this document are from studies of freeways. This project prepared models that predict (1) the frequency of fatal-and-injury (FI) crashes and (2) the frequency of property-damage-only (PDO) crashes. These models were developed and applied to assess the overall effect of PTSU on total and severe crash frequency.
