Pays Briard is a French bus network run by Île-de-France Mobilités, operated by Keolis through his subsidiary Keolis Portes et Val de Brie from January 1, 2021.
It consists of 49 lines which mainly serve the west of Seine-et-Marne and to a lesser extent Val-de-Marne. The network is also completed with three night lines and two demand-responsive transports.
History The establishment in 1946 of the company Les Cars Bizière in Seine-et-Marne, bought by the Transdev group in 2002 then renamed Transdev N'4 Mobilités in 2007, alone developed several bus networks in the west of the department. Indeed, the networks Stigo (Syndicat de transports intercommunal de Gretz-Armainvilliers et Ozoir-la-Ferrière) and Sol'R respectively served the Les Portes Briardes Entre Villes et Forêts community of communes and the Val Bréon community of communes from 2005<.. The "Yerres - Brie Centrale" and "Arlequin" networks respectively served the center of Seine-et-Marne and to a lesser extent, Val-de-Marne.
Several lines of these networks, partly operated by the subsidiary Transdev N'4 Mobilités, merged during the creation of the Pays Briard bus network on January 1, 2023, the date the network began operating under competitor Keolis.
Network development Sol'R bus network Since September 2, 2013, several additional weekday runs have been distributed across the lines 3, 7, 209, 309 et 409.
On September 1, 2014, due to changes in school zoning, the line 3 saw its morning run twice, and the line 409 was reinforced with two additional runs in the morning and one on Wednesday midday.
The thirteen lines were operated by Transdev Darche Gros and Transdev N'4 Mobilités and were only in service from Monday to Friday (with the exception of the line 21, which was also operated on Saturdays), before their transfer to the new public service delegation.
Stigo bus network Stigo (Syndicat de transports intercommunal de Gretz-Armainvilliers et Ozoir-la-Ferrière) is a former bus network operated by Transdev N'4 Mobilités, beginning his service in 2010.
On November 7, 2011, the line 11 was created, providing a link between the municipalities of Ozoir-la-Ferrière and Gretz-Armainvilliers.
From September 2, 2013, following the extension of Lycée Clément-Ader in Tournan-en-Brie, the line 11 has seen the extension of its evening services to the high school without the addition of additional services. On the same date, the line 201 is extended from Ozoir-la-Ferrière to Lésigny via Férolles-Attilly, these municipalities previously only had a feeder service to schools. The extension of eleven services during morning and evening peak hours and the creation of eight services during off-peak hours will connect these municipalities to the urban and administrative center of Ozoir-la-Ferrière. This reinforcement required the acquisition of a standard bus. The line 11 service was extended on September 1, 2014.
On January 8, 2018, during the restructuring of the Sit'bus bus network, the lines 8 and 202 were replaced by the new line A. The line 203 was absorbed by a route modification of the line 502.
On January 6, 2020, the line 201 is split into two lines 200 and 201, the line 11 no longer serves Ozoir-la-Ferrière and a demand-responsive transport is implemented.
On January 1, 2023, Keolis takes over the operation of the four lines of this former network, and makes several changes, notably the extension of the operation of some lines in the evenings.
Yerres - Brie Centrale bus network Before the opening to the competition, sixteen lines of Yerres - Brie Centrale were operated by Transdev Darche Gros and Transdev N'4 Mobilités.
Arlequin bus network Before the opening to the competition, eight lines were operated by four different subsidiaries of Transdev : Transdev N'4 Mobilités, Transdev Darche Gros, Transdev SETRA and Transdev Saint-Fargeau-Ponthierry. Only the line 12 was not transferred to Pays Briard bus network, instead being transferred to Marne et Seine bus network.
Opening to the competition Due to the opening up of public transport to competition in Île-de-France, the Pays Briard bus network was created on January 1, 2025, corresponding to public service delegation number 13 established by Île-de-France Mobilités. A call for tenders was therefore launched by the organizing authority to designate a company that will operate the network for a period of six years. It was finally Keolis, via its subsidiary Keolis Portes et Val de Brie, which was designated during the board of directors on May 25, 2020.
At the date of its opening to competition, the network consisted of the lines 11, 18, 200 and 201 of Stigo, lines 3, 7, 10, 17, 21, 28 (abc), 33, 121, 209, 309 and 409 of Sol'R, lines 4, 20, 23, 24, 32, 34 (ab), 35 (abcd), 37 (abc, rpi) of Yerres - Brie Centrale, lines 5, 6, 7, 10, 14, 21 and 30 (abc) of Arlequin, line 39 of TRAMY, line 23 of Mobilien, and line 16 of the Seine-et-Marne Express. The contract also includes the Noctilien line N142.
Since the network was created, users have noticed numerous malfunctions, such as unserviced departures and drivers not serving some stops, and the lack of drivers.
On September 4, 2023, the line 7 serving Brie-Comte-Robert is split into five lines (1, 2, 3S, 4S and 5S).
Network renaming Since February 17, 2025, the Pays Briard network has been implementing the new single regional numbering system planned by Île-de-France Mobilités to eliminate duplication. Bus lines in the Pays Briard network will now begin with the area code "31", followed by two additional digits, and Express lines will begin with the number of the department to which the network belongs, in this case "77" for the Seine-et-Marne department, followed by two additional digits.
The correspondence between the old and new numbers is as follows: +Network renaming Old New 23 1 2 3 4 5 6 7 3S 209 10 11 14 121 11S 17 18 21° 20 21 28B 23° 24 28C 30B 30C 28A 34B 30A 35B 32 33 34A 35A 35C 37A 35D 39 37B 4S 5S 37C 200 201 309 409 10° 16
