Q:What are Tactile Walking Surface Indicators (TWSI’s)?

A: Tactile Walking Surface Indicators (TWSI’s), are devices with defined sets of patterns that have been agreed upon by International Accessibility Experts, that either provide persons with visual impairments a) warning of a hazard or b) following a direction.

Q:Where did Tactile Walking Surface Indicators Originate?

A: Tactile Walking Surface Indicators were originally developed in Japan in the 1960’s when a member of the Royal Household was visually impaired, and every effort possible was initiated to assist this person’s mobility in the public realm. Since then Japan has spearheaded many initiates for assistive devices, and TWSI’s are still more common than anywhere else in the world.

Cast iron recommended for City of Toronto standard

Results are in after a year-long Pilot Project to determine which four materials of tactile walking surface indicators (TWSI)’s would be recommended as the new City of Toronto standard. And the winner is- cast iron!

In order to comply with the Design of Public Space Standards (Part IV.1 of Ontario Regulation 191/11, Accessibility for Ontarians with Disabilities Act, 2005), which included new legislative requirements to have TWSI’s at the bottom of curb ramps and depressed curbs to provide alerts for those with vision loss, the City of Toronto started a Pilot Project to best decide what standard they should adopt for TWSI’s on their sidewalk surfaces.
