More so, According to the 205 international survey conducted by the institute of Electrical and Electronics Engineer (IEEE) (Vissers et al., 206) found that safety and faith in technology were priorities as the main barriers to users acceptance of AVs. They further indicated that participants of this study express uncomfortable attitude towards they use of AVs for children transportation. Similarly, (Schoettle & Sivak, 204) survey studies conducted in the United states, the United Kingdom and Australia showed that 90% of the respondents had concerns that AVS would, in general, not drive and respond to dynamic situations as well as human drivers. They were particularly concerned about the possibility that automated vehicles could get confused in unexpected traffic situations. This concern about safety issues and automated vehicles not performing as well as manually driven vehicles was also found in another study of (Schoettle & Sivak 204b), which included respondents from China, India and Japan. In their survey studies, Schoettle & Sivak also explicitly
asked whether respondents were concerned about the interaction between pedestrians and cyclists with automated vehicles. In the English-speaking countries, many respondents indicated to be very concerned: 42.% in the United States, 35.6% in Australia, and 33.4% in the United Kingdom. In the Asian countries, the Chinese appeared to be the most concerned (42.6% very concerned), followed by the Indian people (40.4%) and the Japanese (22.2%).
From the various studies above, it is seen that not all people consider the development and transition of AVs into the present mobility system desirable as many show concerns about their safety consequences. Moreover, it has been shown that peoples behaviour are influence by their attitude, and beliefs (Ajzen, 20) as such lack of confidence in AVs will influence the behaviour of pedestrians and cyclist when they meet and may results to traffic crashes. So, if AVs need to be incorporated within the present mobility system, apart from technical feasibility, public acceptance needs to be taking into considerations as well.
