As in the case of BRT schemes, authorities have negotiated with incumbent operators to annul individual concessions in exchange for giving priority in granting new concessions to enterprises formed by these incumbent operators. While no smart card has yet been introduced, buses acquired by concessionaires are required to be prepared for introducing this technology in the near future. The BRS corridors introduced to date are Valenciana-Tacubaya, Chapultepec-Palmas and Pefion-Panteon San Isidro. The price of the service is MXN 7 (USD 0.5).
