Dynamic passenger information
From Wikipedia, the free encyclopedia
Dynamic Passenger Information (DPI) is intended to inform public transportation passengers about currently available runs. As such, data from long term, static, predefined public transport timetables can be amended with continuous, dynamically determined timetable deviations. DPI consequently augments traditional (static) passenger information.
[edit] Application
Passengers frequently demand appropriate real time information from transportation firms. This is to be delivered, unprompted, for each deviation from the printed static timetable.
