FlashCast provides an affordable digital advertising platform on public transit vehicles in developing countries. It collects anonymous sensor and user data from buses to provide insights into public transit usage, road safety, and more. In a trial in Nairobi, FlashCast conducted a family planning survey via SMS on buses that collected over 4,000 responses. The data and platform could help address information gaps and issues like road safety. However, challenges remain around distributing ads, educating users, and establishing trust in SMS services.
