Case Studies into CPFM

March 2022

The Federal Highways Administration (FHWA) has posted on its website the results of two studies into how data collected by continuous pavement friction measurement (CPFM) has been used to improve road safety.

The case studies, which can also be viewed on WDM USA’s Friction Resource pages, reveal how Florida DoT utilized CPFM data for the first time to instal high friction surface treatment at intersections, to reduce crashes and improve pedestrian safety.

The FHWA say CPFM is an established, proven approach, which has been used for several decades in other countries, and it could revolutionize the role of pavement friction in framing an understanding and management of the safety performance of America’s roads.

CPFM equipment measures pavement friction continuously, through tangents, curves and intersections and can prevent many roadway departure and intersection related crashes, resulting in fewer serious injuries and fatalities.

The FHWA encourages the use of CPFM to provide comprehensive pavement friction data, combined with existing safety data and analysis, to create an overall pavement friction management program anchored in safety.
