Contextual information in user information systems in public transportation: A systematic review

The accelerated urbanization rates have brought along an ever-increasing number of vehicles, which, in their turn, causes serious delays in people's daily travels. Users of public transportation, in particular bus passengers, have suffered the most, due to the lack of information about transportation means and traffic conditions. This creates anxiety and uncertainty about the travel, especially on metropolitan regions in developing countries. In this light, User Information Systems (UIS) aim to provide precise information, taking into account the context of the passenger and of the traffic. Hence, it is possible to better support users decisions and increase users' trust on the transportation means reliability. This work presents a systematic literature review, which aims to identify how (if at all) contextual information is used by Public Transportation User Information Systems.
