Atlas de l'exposition aux pollutions atmosphérique et sonore
Objectives of the Atlas

Cycling is becoming an increasingly popular mode of transportation in many North American and European cities. Mexico City is no exception, having seen a constant increase in the number of cyclists, especially in neighborhoods around the Reforma area, with increases of more than 30% between 2011 and 2012 (IDTP, 2013).

Compared with the car, the benefits of use of the bicycle in urban areas on people's health and well-being are now well known. On the one hand, cycling allows people to increase their level of physical activity and thus improve their cardiovascular fitness, while reducing the risk of chronic diseases, certain types of cancer, overweight and obesity, and fostering better mental health and quality of life. Traveling by bicycle also has positive effects on the environment in urban areas, with the bicycle producing far less air pollution and noise than the car. Despite these widely-documented positive benefits, cycling in urban areas be associated with health and safety risks due to potentially high levels of exposure to air pollution, road noise, and high traffic density. However, according several recent studies, the benefits of changing one’s mode of travel from the car to the bicycle outweigh the risks incurred.

The main objective of this study is to measure cyclists’ exposure to air pollution and road traffic noise ours in Mexico City. The aim of the Atlas is to meet three sub-objectives:

  1. Analyze the levels of exposure to noise and air pollution;
  2. Analyze the doses of pollutants inhaled along the routes as well as the levels of physical activity;
  3. Map the trips and the results.

 

Data used

Nineteen bicycle trips were made from February 27 to March 3, 2017 in five districts of Mexico City (Miguel Hidalgo, Cuauhtémoc, Álvaro Obregón, Benito Juárez et Coyoacán) for a total of 137 kilometres and 11 hours. For a detailed description of the methodology, see the methodology section.

 

Funding

This research project has been funded by the Canada Research Chair in Environmental Equity and City. It also uses a research infrastructure (the facilities of the Environmental Equity Laboratory) funded by the Canada Foundation for Innovation ( CFI).
