Pablo left a stable job as an architect to address the transportation problems in Santiago, including traffic jams, air pollution, and lack of both parking and public transit. “Too many cars are used in an inefficient way, carrying just one person on each trip,” says Pablo. He and two university friends developed a web interface, A-dedo, which allows users to share their rides with others—and also save money and reduce carbon emissions. New applications are also being developed for mobile phones and GPS systems. Pablo and his team have signed contracts with several companies and universities in Chile and look forward to expanding the service to other countries in Latin America.
