About the research

This effort is designed to build on the work completed in Phases I and II. In Phase I of High Friction Surface Treatment (HFST) for High Crash Locations, a methodology was developed to systematically identify potential HFST candidates and mainline horizontal curves on primary and secondary roads based on crash experience. Through an iterative review process with the Iowa Department of Transportation’s (DOT’s) Office of Traffic and Safety, and input from appropriate highway agencies (county and Iowa DOT), 14 total curves were identified for HFST treatment in 2017. After working with all agencies involved, 9 sites received the high friction surface treatment in the summer of 2017.

The objective of Phase III is to continue the collection of friction and other pertinent data for all available treatment sites and monitor HFST performance and safety data for a two-year period. Crash data from before and after will also be collected.
