Reducing CO2 emissions
The system uses advanced data analytics to identify the transport hub user’s tastes and preferences to cater to their needs based on different parameters (age, gender, likings, etc.). Similarly, the app gathers information about end-to-end routes in the city to identify and suggest new uncovered routes to the ‘Consorcio Regional de Transportes de Madrid’.
At the height of the climate crisis, projects such as ‘Deja tu huella’ act as tools for education and awareness-raising for citizens about the importance of environmental protection and promoting sustainable mobility in the city.
