Its main function is to integrate and articulate urban public transportation in the Lima metropolitan area.

During the mandate of Susana Villarán (2011-2014), a transportation reform was carried out that indicated the renewal of buses using the Bus Patrón as an example, scrapping, the cutting and changing of some routes, the promotion of transfers, the whereabouts ordinance and ended with the establishment of the first complementary corridor that began the Integrated Transportation System,[3] but initially had conflict with the municipality of Callao.

[4] Previously in her electoral campaign in 2010, Villarán as well as other mayoral candidates promoted the creation of an Autonomous Transportation Authority.

[12] In 2023, the organisation proposed a transportation reform in Lima and Callao, but it was interrupted after the retirement of Ana Jara by the central government.

[13] In addition, at the end of that year, operations began on the northern expansion of the Metropolitano and a section of Line 2 of the Lima Metro.
