It is considered that the public transportation of passengers assists daily around 15 million trips, passenger-trip per day (P-T/D). However, the fast population increase and the insufficient development of the collective public transportation has caused an increment in the vehicles of little capacity with high energy consumption. This situation has contributed to the increment in the traffic congestion and to worsen the quality of the air. The consequences for the public health derived from the environmental degradation have also been for 20 years copiously detailed and analyzed by many international agencies. It is necessary that this City establishes a redesign in its tariff politics of the transportation so that it is centered in the inclusion of the costs and benefits (economic, social and environmental), in all the ways of transportation and it should be structured in such a way to be flexible and dynamic through time and that allows the efficiency, the equity and the sustainability.
