Studies have shown that proximity to roadways with heavy traffic has been linked with increased incidence and prevalence of a range of health effects such as adverse birth outcomes, dementia, asthma, and increased risk of bronchitis, wheezing, deficits in lung function growth and airway inflammation, especially among children. In Mexico, 103 urban areas have air quality monitoring, whilst more than 2,000 cities lack any information and only 29 have monitoring systems that are robust enough to estimate exposure. This poses serious limitations for environmental and health authori- ties when aiming at assessing current exposure levels to Traffic-Related Air Pollution (TRAP) with the purpose of designing and implementing policies to reduce the impacts of poor air quality in the population. This study proposes an approach to estimate the population potentially exposed to TRAP using Space Syntax’s accessibility index as the urban form variable. We selected the ten most accessible roads of the five Mexican cities to estimate the proportion of vulnerable population (residents, employees, schoolchildren, hospital patients) with the highest potential expo- sure to TRAP at a distance of 500 m. Our findings show a similar proportion of the population continually exposed to TRAP due to the proximity to roads with heavy traffic than studies using more complex models. Finally, this study presents alternatives to reduce current population exposure to traffic emissions in Mexican cities.TextoengopenAccesshttp://creativecommons.org/licenses/by/4.0HUMANIDADES Y CIENCIAS DE LA CONDUCTA::CIENCIAS DE LAS ARTES Y LAS LETRAS::ARQUITECTURA::URBANISMOSocial SciencesArtículoApplied Spatial Analysis and Policyhttps://orcid.org/0000-0003-4125-8991https://orcid.org/0000-0003-4140-9673Traffic-Related Air PollutionUrban FormPopulation exposureUrban PlanningMexican cities119Suiza / Switzerland
