Enjeux, mobilité, accessibilité et risques. L'exemple du district métropolitain de Quito (Équateur)

This paper presents the main results of a research on the risks incurred by the Metropolitan District of Quito considering the people’s mobility and areas accessibility issues. This analysis relies on a methodology implemented within the framework of a programme called “Information System and risks within the Metropolitan District of Quito” carried out by the French Development Research Institute (IRD) in partnership with the Municipality of Quito. The paper describes the main GIS processing used to (i) identify the critical transportation infrastructures, (ii) the assessment of their vulnerability, (iii) the reduction of urban areas accessibility, and (iiii) the risks incurred.
