Passenger information

A passenger information system (PIS or PIDS) is an automated system for supplying users of public transport with information about the nature and state of a public transport service, through visual, voice or other media. They are also known as Customer Information Systems and Operational Information Systems. Among the information provided by such systems, a distinction can be drawn between:1st generation termini indicator on the RER line A2nd generation termini indicator on the RER line BLED indicator on the Paris MétroA variant of the Métro's LED indicator used on Paris Métro Line 13 utilizing a lighted arrow indicating the terminus of the next trainTV screen used on Paris Métro Line 14LCD used on Paris's bus system A passenger information system (PIS or PIDS) is an automated system for supplying users of public transport with information about the nature and state of a public transport service, through visual, voice or other media. They are also known as Customer Information Systems and Operational Information Systems. Among the information provided by such systems, a distinction can be drawn between: Static information has traditionally been made available in printed form though route network maps and timetable booklets at transit stations. However most transit operators now also use integrated passenger information systems providing either schedule-based information through a journey planner application or schedule-based information in combination with real-time information. Real time information is an advance on schedule-only information, which recognises the fact that public transport services do not always operate exactly according to the published timetable. By providing real time information to travellers, they are better able to conduct their journey confidently, including taking any necessary steps in the event of delays. This helps to encourage greater use of public transport, which for many countries is a political goal. Real-time information is provided to passengers in a number of different ways, including mobile phone applications, platform-level signage, and automated public address systems. It may include both predictions about arrival and departure times, as well as information about the nature and causes of disruptions.
