Measuring HFST Safety and Functional Performance Over Time

HFST is a pavement treatment with exceptional skid-resistant properties not typically provided by conventional materials such as asphalt concrete or Portland cement concrete. It is intended to reduce crashes by enhancing the skid resistance quality of the pavement at locations where vehicles often brake excessively, and conflicts are high.

As a promising initiative to improve safety, HFST was implemented by the British Columbia (BC) Ministry of Transportation and Infrastructure at several signalized intersections in the Lower Mainland and Vancouver Island in 2018 and 2019. To provide early evidence of the safety effectiveness of the implemented HFST initiative, the University of British Columbia completed a safety assessment study in 2021.

Typical crash types targeted by HFST are road-departure and rear-end, usually observed at intersection approaches, off-ramps, and horizontal and vertical curves. The objective of this webinar, held March 23, 2023, is to present the before-and-after safety effectiveness evaluation of the implemented HFST at intersection approaches.

Speakers include Joy Sengupta, P.Eng, RSP1, Principal Highway Safety Engineer and Mohamed Essa, Senior Road Safety Engineer, both from the BC Ministry of Transportation & Infrastructure, with David Merritt, P.E., Project Director with The Transtec Group of Austin, Texas (Moderator).
