Public transport may be undergoing an important transformation following the arrival of autonomous vehicles. Researchers, think thanks as well as consulting companies have designed many scenarios based on trend analysis of three main dimensions: technology, regulations and uses. The user level of acceptance for autonomous driving represents a key point for any prospective study. Therefore, this article aimed at proposing a use case daily scenario by focusing on the user. We analyse more specifically the implementation of autonomous vehicles for micro transit and commuting by studying user opinions via two field surveys. Discussion with users help us to build and test a use cases scenario and to picture personas whose characters will allow decision makers to better figure out the conditions to leverage the citizens level of acceptance for robomobility.
