A Wayfinding Pilot Study: The Use of the Intelligent Public Vehicle by People with Visual Impairment

This article reports on a study that explored the feasibility of a new public transport vehicle for travelers with visual impairments. The Individual Public Vehicle (IPV), considered for the city of Clermont-Ferrand in France, is an “intelligent” vehicle that features an automatic guidance system which can transport one or two people from public transport, such as a tram, to a final preprogrammed destination. The study participants were 9 men and 6 women with visual impairments, the majority of whom used public transportation frequently. The participants completed a questionnaire concerning three steps in the movement between tram and IPV: descent from the tram, movement between tram and IPV, and boarding the IPV. There were three possible strategies for getting to the IPV: a tactile and/or visually adapted map, an auditory signal from the IPV, and a remote-control activated voice information message sent from a terminal. For boarding the IPV, participants chose one of two adaptations: a rectangular plate placed in front of the vehicle door, or a voice information message. The questionnaire results showed participants rating the attention required to descend from a tram to be higher than that evaluated for movement between the two forms of transport and for boarding. All the adaptations for transition between modes of transport and entering the IPV induced a high level of satisfaction among respondents; however, the adaptation involving a voice message was evaluated as being less stressful than the others. The authors conclude with a discussion of the implications of these findings for further testing of the IPV in real-life situations.
