Urban Transportation System

The number of passengers, trips per person, type and number of vehicles, electric public transport, subway characteristics and the general transportation net were provided by the ZMCM authority (http://www.ddf.gob.mx/ag/num/transp.html ).

Passengers. The number of passengers within the Metropolitan Area is continuously increasing, although the rate of increase is slowing. Most of these passengers are public transportation users.

Reasons for travel. The main reason to travel is to move from home to work or school, and back again. Peak traffic occurs at 8:00, 14:00 and 18:00 hours on weekdays.

Transportation. According to information provided by the city government, in 1997, most people travelled around Mexico City using public transportation (74.1%).

Roads Characteristics. Important elements of the road transport system within the ZMCM are a circular freeway (the Perifrico), 23 main one-way roads (ejes viales) and the primary and secondary transport nets.

Vehicles in Mexico City. Mexico City, being the biggest urban population centre in the world, and spread over a large area, has very demanding transport needs. Eighty four percent of its inhabitants use public transport, which accounts for 7% of the total number of vehicles on the roads. Private vehicles make up 85% of the remainder, and freight 16%. This situation creates the following urban problems: heavy vehicles, pedestrian movement, waste of time, overcharging of roads, high pollution due to fuel consumption and low efficiency of public service.

Although private cars are more common than any other type of vehicle on the roads (2,327,930), they only used by a small minority of the total population. The most important transportation system for the majority of people within the ZMCM is the METRO (Metropolitan Transportation System) which carries than two million passengers every day.

In addition to the METRO, there are two other electric transportation systems: a small tram network and the so called 'light train' which account for 1.8% of journeys by the public.

There is also a trunk system transportation (mainly diesel engines) sponsored by gorvernment of Mexico State. The objetive is to improve and regulate the suburban transport that circulates within the counties of the State of Mexico and in the Metropolitan Area. Furthermore, there are a considerable number of suburban buses powered by diesel engines. Many are in poor repair and have old engines. This is one of the main causes of high levels of pollution in Mexico City.
