The passenger information (PIS or PIDS) system is an automated system for supplying users of public transport with information about the nature and circumstances of public transport services, through visual, sound or other media. They are also known as Customer Information Systems and Operational Information Systems. Among the information provided by the system, differences can be drawn between:
- Static or schedule information , which is only occasionally changed and is usually used for pre-departure trip planning.
- Real-time information , comes from an automated vehicle location system, which changes constantly as a result of real-world events and is typically used during travel (especially how close the service is running) to the time and time of the stop, but also the incidents affecting service operations, platform changes etc.).
Static information has traditionally been provided in print via route network maps and schedule books at transit stations. But most transit operators now also use an integrated passenger information system that provides schedule-based information through the application of a travel planner or schedule-based information combined with real-time information.
Real-time information is the progress of schedule information, which recognizes the fact that public transport services do not always operate exactly according to the published schedule. By providing real-time information to travelers, they are better able to travel confidently, including taking the necessary steps in the event of a delay. 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 variety of ways, including mobile phone applications, platform level placemats, and automated public address systems. This may include good predictions about arrival and departure times, as well as information about the nature and causes of the disorder.

Issues with provision of passenger information
There are four key considerations for the provision of passenger information (static or real time):
- Data availability. Information can only be provided where available, and gathering information can be an intensive resource. Also, there may be difficulties with coordinating data sharing between multiple organizations.
- Data accuracy. Collect error-prone information. Also, the prediction algorithm is not perfect, and real-time announcements may be wrong for this reason.
- Obtain information to passengers. Various dissemination mechanisms can be used, but it is not always easy to ensure that the correct information reaches the passenger when it is most needed. Information overload should be avoided.
- Latency or Response time . Terms of information should react quickly to passenger requests or real-world updates. There is no point in announcing the service three minutes after departure.

Real-time arrival prediction system
Current operational information on the current service is collected from the automated vehicle location system (AVL) and from the control system, including the incident arrest system. This information can be compared algorithmically with published service schedules to generate predictions about how the service will run within minutes to the next hour. This may be informed by additional information: for example, the bus service will be affected by congestion on the road network, while all services may be affected by adverse weather conditions.
Economic reasons
Capital and revenue costs for tourist information systems can be calculated with reasonable accuracy. However, the derivation of tangible financial benefits is much more difficult to establish and, as a consequence, there is little research. This directs the business model for information systems to "softer" benefits such as tourists' trust, etc. It should be noted that there should be actual value because individuals are willing to pay for systems that give them access to real time data related to travel. The difficulty is determining what this is for everyone and perhaps every piece of hardware on the roadside. Even less is known about the long-term effects of access to this type of service. The only long-term study is from 2012.
Communications channel
Information may be communicated via any electronic media, including:
- Mobile phone app
- Displays LEDs and filters inside stations
- Internet via website
- the phone (either a manned bureau service or an automated answering system)
- touch screen kiosk for self-service (eg at customer's office)
Additional considerations include:
- How the system will present information for disabled travelers
- Whether the system will be able to provide information in multiple languages ​​
Information
The information provided by the passenger information system depends on its location, and the technical scope (eg how large the display is)
At station or stop, it is normal to provide a current prediction about:
- Which services are operated by the next vehicle to arrive, including routes and destinations.
- When this vehicle arrives
- How close goes to the schedule.
- Similar information for some of the following services.
- General advice on current travel disruptions that may be useful to passengers in understanding their implications for their travel plans.
In vehicles, it is normal to provide current predictions about:
- When the vehicle will arrive at the next station or stop (express or long distance service)
- Suggestions for connecting services.
Personalized channels (web, mobile device, or kiosk) will usually be set to mimic the look of the station or stop but may also be associated with the trip planner. Using such a system, passengers can re-plan their trip to account for the current state (such as canceled services or excessive delays).
Example
French
In Paris, France, the SIEL indicator system (abbreviated from SystÃÆ'¨me d'information en ligne) is installed on the RER, Paris MÃÆ' Â © tro and on 250 bus routes on the RATP bus system.
In RER, there are 2 types of indicators used, the first generation model that only shows the term train stops at the station through the use of square lights located next to words containing the terminus name, and a second generation model that includes an LED screen above the square lamp show terminus and train service. This display is only used on RER line A, RER line B and in Gare de ChÃÆ' telers - Les Halles station on RER line D, and can be inaccurate at times due to lack of communication between SNCF and RATP, both operators of RER.
In Paris MÃÆ' Â © tro, there are two types of information display systems; LED display numbers mounted on all MÃÆ'Â Â tro lines (except line 14), used since 1997, and television screens installed in all stations on line 14. Showing this indicates the time required for the train (and subsequent trains after that)) to reach a particular station.
On the bus network in Paris, monochrome LCDs have been used since 1996 to show the time it takes for buses on the bus route to arrive at the bus stop, after a two-year test period on several bus routes.
German
Deutsche Bahn AG offers Travel Information System (RIS). It shows the current train time compared to the published schedule, as well as the known delays and expected train arrival and departure times. This information is available for rail conductors (via SMS) as well as for passengers via loudspeakers at railway stations or board schedules on the internet. VRR and VRS transport schedule information systems also process RIS data. Data can also be questioned in real-time via mobile devices such as mobile phones.
The RIS system began in 2003 and in 2007 is planned to have 30,000 trains equipped with the required train registrants (electronic train numbers). In the accompanying program, the older fold-screen display information is replaced by an electronic dot-matrix billboard. While large stations have a multiple-platform display, Deutsche Bahn network operators are developing standard DSA systems for smaller stations with one line. In 2011, federal funding was provided to supplement 4,500 additional stations with DSA (Dynamischer Schriftanzeiger
The federal grant comes along with the EBA railway authority commands in 2010 to have all stations connected to the travel information system to announce delays with electronic sign or loudspeakers. The Deutsche Bahn operator tries to proceed legally against orders for stations with very low frequencies but it loses all lawsuits by 2015. It is given 18 months to complete the remaining stations done with the DSA. The DSA system has a GSM radio module for receiving text messages that will be displayed in a news ticker style that moves horizontally. When no time delay is currently displayed statically on the LED 96A-8 dot-matrix display. Speakers can be optionally mounted on top.
United Kingdom
The National Railway Station is equipped with a visual platform display and audio announcements that indicate the next service or service of the platform, and which warns passengers to stay away from trains that are not scheduled to stop, are not being used, or that will soon stop. depart. In addition, sales and ticket offices have a large screen showing all the services available on the station for an hour or more, and (at major stations) the full route of the service and any applicable restrictions (eg ticket type, catering service, train bikes). It should be noted that many of the smaller and less used train stations do not have such systems, but rather have "passenger help points" connecting users by phone to the control room by pressing the "Information" button.
This information is available online on National Rail and on mobile devices.
Most Underground London stations have "countdown" on each platform. This is simpler than the national rail view because in many cases each platform serves only one line and there is little or no variation within the constraints of freight and destination served. Audio announcements are also done regularly.
Local authorities and some transport operators provide an electronic version of the bus timetable to the Traveline information service covering all modes of public transport, and from there to other information services such as Transport Direct and Google Transit.
The deployment of real-time bus information systems is a gradual process that currently extends to about half of the national fleet and most downtown stops, but relatively few suburban and rural locations. The first use of this system is in Brighton and Hove. The Traveline NextBuses information service provides the next departure from every bus stop in the UK, and some trams as well. This information is real-time where the real-time feed is connected, if not the scheduled time is given.
Government-sponsored Transport Direct projects provide travel planning in all modes of transportation (including private cars) and are increasingly associated with real-time information systems.
United States
Real-time passenger information was brought to US riders by a NextBus company, a small startup, in 1999. The first system was installed in Emeryville, California, and later in San Francisco, California. In 2012 both systems are still in operation.
Washington Metro installed PIDS at all of its stations in 2000. The system provides real-time information on the arrival of subsequent trains, delayed trains, emergency announcements, and related information. Metro also provides current trains and related information to customers with conventional web browsers, as well as smartphone users and other mobile devices. In 2010 Metro began to share its PIDS data with outside software developers, to be used in the creation of additional real-time applications for mobile devices. Free apps are publicly available on major mobile device software platforms (iPhone/iPad, Android, Windows Phone, Palm). The system also began providing real-time train information over the phone in 2010.
The New York City Subway began installing a public/customer information address, commonly known as a "countdown clock", at its station in 2007. In 2012, the system began offering SubTime, iPhone websites and apps for estimated train arrivals in real- time. for some of its subway services, and arrival data is shared with outside software developers to support the creation of additional applications. There are also PIDS installed on several Regional Bus Bus MTA routes over the years, but for the most part, MTAs offer real-time bus tracking through another website/app called BusTime.
Amtrak has deployed PIDS to the entire Northeast Corridor. Boston MBTA and MBCR have also been distributing PIDS.
In 2010, PIDS is deployed with integrated messaging, which may include information streamed to mobile devices, phones, and translated directly to voice announcements. Text to Speech products have been designed to convert PIDS data into speech in a selection of more than 20 languages.
