A request to Google Maps Traffic is performed by the use of the library selenium for Python. A screenshot is carried out each 10 minute in a specific zone of Quito, which is centered on the neighborhood of Belisario. The exact coordinates of the geographic area of interest are −0.181661, −78.4987077, which is 1.2 km southwest from the center of the traffic map. Two kinds of images are stored: the one with traffic (**Figure 1a**) and the another without traffic (**Figure 1b**). It is necessary to save these two different types of pictures in order to proceed with the next step that consists of isolating the traffic information only (**Figure 1c**).
