Intelligent Transportation Systems (ITS) or Transport Telematics
have been used for many years in Public Transport (PT) for various
purposes, including Automatic Vehicle Location (AVL), Real Time
Passenger Information (RTPI), and Vehicle Operational Data Gathering
and Archiving. From the users’ (passengers) point of view,
provision of information is definitely the most important service
ITS can offer. Information can refer to real time situations such as
bus arrival/departure time, service disruptions and other related
events as well as to other PT information regarding service
schedules, fares, transfers, etc.
