While Mexico City’s population keeps growing (currently at 23 million), it has become the city with the worst traffic and one of the most polluted cities in the world. To address these challenges, the city has invested in a mostly carbon-free multi-modal transit system consisting of the Metro subway, MetroBus BRT, trolley and regular bus lines, regional rail and light rail, a bike share system, and one of the largest urban gondola systems (CableBus) on the world. Outside of the city boundaries it also connects to the state’s bus and gondola lines. To serve riders from all income levels, it is also very affordable (7 pesos, about 40 cents, less for students/seniors). A single payment system makes it easier to use any of the different modes. This article explains the changes during the last decade and potential learnings for Seattle.
