The transportation systems in Indonesian cities tend to favour personal vehicles. In Jakarta the number of personal vehicles has tripled inthe last ten years while public transport remains stagnant. On the other hand, roads are continuously built to accommodate the increasing number of cars and motorcycles. It leads to persistent traffic jams and large consumption of fuel causing air pollution and emission of greenhouse gases. Pelangi Indonesia works to promote an urban transportation system that adheres to sustainable development through integration between low emission per capita modes of transportation with non-motorized transportation in urban area.
