A system of online information is a whole of materials making it possible to inform the passengers of a line or a joint grid system, generally on the spot of waiting, or inside even of the modules of transport. Information relates to mainly the hours of passage at, and possibly the event stagnation points in connection with the grid system (for example: accident, strike).

the RATP employs such a system, indicated by the initials SIEL in the Métro of Paris.

System SIEL also equips the stations the RATP with the lines has and B the Parisian RER. Not to confuse with the similar system used in SNCF railway stations, baptized Infogare.

It is currently also present on nearly 160 drunk lines of or trams of Paris or Île-de-France.

SIEL in the Parisian subway

In the subway, this system is pressed on a screen with diodes which comes to replace the old panels of direction in medium of quay. It indicates the latency before the two next trains, or the next train if the station is very close to the terminus (in the direction departure). In the case of the lines with branches (line 7 and line 13), in the direction concerned with the junction, they are times of the 4 next trains as their destination which are posted.

In certain stations, SIEL is accompanied by a high speaker. It is the case of the stations White House and Place of Italy on the line 7 in the direction Courneuve - May 8th, 1945 - > Mairie of Ivry, Villejuif - Louis Aragon. These loudspeakers are there to give the direction of the next train to the badly conspicuous people. In certain stations of line 1, in fact the latencies are stated aloud.

History

The RATP initially tested three versions of posting for system SIEL on the lines 3 and 13 in 1997 and 1998. These tests made it possible to choose the best interface for the traveller according to studies near the customers.

On the line 3, the panels were more complete than on the line 13, several lines of characters in electroluminescent diodes thus gave the indication of the direction and the latency for the three next trains.

However the preference of the travellers went to the simpler version of the 13, that which we currently know and who indicates only the two next trains. This solution, adopted in 1999, gradually was deployed on the line 13 in 2000 then on the 4 in 2001.

SIEL was brought into service on these lines in November 2002 for the line 13 and in December of the same year for the 4.

After the lines 4 and 13, they are the lines 1 and 7 which was equipped in a simultaneous way at the beginning of 2004.

Then it was with the turn of the lines 11 and 2 in a very restricted time interval.

Currently

Currently the lines 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14 are equipped. The system not being yet fully operational on the lines 6 (installation of the cables and system of detection) and 10 (Adjustment of the system compared to the traffic of the trains).

The implementation of SIEL on the lines 3 (a) and 7 (a) will not be carried out. There are not sufficient stations to equip these two lines.

Case of the line 14

The line 14 being relatively recent, it is equipped with a specific system conceived since its creation. It has on its quays TV screens indicating since July 2004 the latency to ten second near. This precision is made possible by the automatisms and the computers which control the trains.

To note that these TV screens are cathode screens, and that the station Saint Lazare which had screens LCD at the time of its opening with the public in 2003 saw these screens replaced by cathode screens during the year 2005.

Features

• the panels post the latency in minutes and in each direction of the two next trains or of only one train if the station is very close to the terminus (in the direction departure).

• When the train is announced to the approach, the zone of posting of the latency concerned with this train flickers with " 00"
• When the train is with the stop, the panel posts " 00"
• In the event of dysfunction or of important disturbances on the line, all the zones of posting post the double character ". " or " - - "
• In the event of delay of 1st or 2nd train the latency flickers ex: " 38" or " 74" or
• the latencies are updated all the 15 seconds
