This project addresses the analysis of the movements of elderly pedestrians in the city of Bogota, through the collection and measurement of data at the traffic-light intersections with the highest number of traffic accidents. The need to carry out this study stems from the identification of the vulnerability of this road actor in terms of their participation rate in traffic accidents, as well as from the lack of research regarding the characteristics of their mobility and consequently the measures that should be taken to guarantee their safe mobility. The methodology used focuses on the identification of traffic-light intersections, where information should be collected considering the density of road accidents, the construction of a mobile application as a technological tool for the measurement and collection of pedestrian displacement variables associated with the study users, the execution of perception surveys to the affected users, the calculation of traffic variables and the analysis of the results obtained.
