“Brasilia is not a city designed for cyclists or pedestrians. It’s a city designed for cars”. This phrase is very common to be heard by the Brazilians citizens. Despite that fact, it seems that the Government is changing that image of the city. The Government of the Federal District is implementing 600 km of bicycle paths until 2014 . After this achievement, Brasilia will have one of the world's largest bicycle paths in the world.
The effort that the Government of the city of Brasilia is performing is the result of the perception that the current model of transport in which the overwhelming majority of the city residents use car as transportation is not a sustainable one. It is well known that the prioritization of the use of cars in the whole world contributed to the increase of pollution, traffic jams, sedentary life and for an irrational use of the space. The environmental resources are limited in contradiction to the human’s needs - that way, since the use of cars demands the use of fuel, that consists in an limited resource, it is not sustainable to maintain such a high level of car dependency1.
Since the first oil crisis, cities from all over the world saw the bicycles as an effective and lower cost mean of transportation and decided to invest on it   . In Amsterdam, the bicycle system become so big that one of the main causes of the delay and overspending lays in the renovation of the Rijks Museum was the construction of a bicycle tunnel .
For its effort to build such a large bicycle path, it´s clear that Brasilia is not different. But, the construction of an enormous bicycle path is just one of the Government challenges. For this mobility plan becomes successful it will be necessary to deal with some challenges. Thus, the aim of this work is to propose ways to solve those challenges, considering the reality of Brasilia and evaluating, when possible, similar solutions adopted by other cities. But first, we shall discuss what are the advantages and disadvantages of this type of transport.
Pros and Cons of Cycling
The use of bicycles as a mean of transportation has several advantages for the users, for the population of the city and for the environment :
Increase of physical activity. Regular physical activity and/or active lifestyle results in proven health benefits, and its practice is recommended by the World Health Organization, both for disease prevention and for the promotion of health   .
Reduction of traffic jams. The more people use bicycle, the lower will be congested.
Reduction of CO2e (Carbon dioxide equivalent) emissions. It is estimated that the production, maintenance and operation phases reveals of a bicycle release about 21 grams of CO2e, bus emits about 101 grams of CO2e and car emits about 271 grams of CO2e (per passenger kilometer travelled) .
All these benefits contribute to a better quality of life of the cyclist and the entire population. Unlike the advantages, disadvantages only...
