Forensic Engineering Use Of Walkway Traction Testing

Abstract

Pedestrian Fall Events Are Frequently Linked To Slippery Walkway Surfaces. Friction Is The Measured Quantity At Issue In Traction Testing Which Has Been Conducted Using Various Devices For Over 80 Years. The Various Available Devices (Called Tribometers) Each Have Their Advocates, Resulting In A Certain Amount Of Controversy. Robust Analysis Of Walkway Traction Requires An Understanding Of Individual Tribometer Characteristics And Knowledge Of Potential Limitations In The Ability To Test Certain Surfaces & Contaminants. It Is Also Necessary To Understand The Status Of Relevant Traction Testing Standards And To Be Familiar With Current Research Which Links Tribometer And Human Subject Testing To Provide Required Friction Values For Safe Pedestrian Ambulation.
