In the Metropolitan Area of Mexico City, the majority of journeys by collective transport are made by means of ‘licensed public transport’, a semi-formal offer made up of small and medium capacity vehicles operated by many small private operators. This type of transport played a very important role in the Mexican capital: on the one hand, it marked one of the conditions for urbanisation; on the other hand, despite its countless shortcomings, for many years it gave the population the opportunity to move around this nmense metropolitan. However, today this inclusive role seems to be reaching its limits in the most recent periphery of the city, where a new model of urbanisation is developing: large closed residential units with formal social habitat. In these places, access to mobility is a major problem for residents, and public transport therefore becomes a key factor for social inclusion.
