Usability evaluation of detectable warning surfaces in Quebec City (Canada): an exploratory study.

The results of this study provide important information concerning the usability of detectable warning surfaces for partners and stakeholders in Quebec City and also contribute to the international literature in this field.Implications for rehabilitationDetectable warning surfaces increase the readability or use of road infrastructures by people with visual impairments. They make it easier for them to get around independently.This project supports the importance of establishing an effective communication plan, particularly with the aim of clarifying the contexts of implantation and the messages transmitted by the detectable warning surfaces to the people with visual impairments. Training could systematically be offered to them by an orientation and mobility specialist.It is also important to inform and educate the general public and bus drivers about the presence of detectable warning surfaces. Information could be transmitted via some community organizations and the public transit networks.In order to effectively coordinate the implantation process of detectable warning surfaces, communication and consultation between the various stakeholders are essential, including the designers, the municipalities and the concerned government authorities.
