An Approach to Evaluating the Usability of Public Transport Journey Planners
نویسندگان
چکیده
Public transport journey planners support a common decision need, and have become popular especially with the availability of real-time tracking data for trip planning and the travellers’ ubiquitous access to the web. This paper, however, takes a usability perspective. The need for assistance in journey planning will vary depending on factors such as the familiarity of the traveller with the route or the complexity of the route. Accordingly this paper will suggest a novel, formal evaluation approach for the usability of public transport journey planners based on the pragmatic information content of journey advice for different traveller categories. The approach is generic and can inform the design of intelligent systems as well as provide a measure for the quality of existing public transportation journey planners.
