Transit advertising places ads on public transportation systems and in transit environments. These ads may move through a city on vehicles or appear in areas where people wait and travel daily. Billboard advertising places ads in fixed locations, such as highways, major roads, or prominent urban sites. These ads remain in one position and rely on passing traffic for exposure.

Transit advertising is a form of out-of-home (OOH) marketing where promotional messages are displayed in or on public transportation vehicles and transit stations. This includes buses, taxis, subways, trains, trams, and the areas around them, like bus stops, metro platforms, and transit shelters. Transit advertising doesn’t just follow your audience—it meets them where they’re already going.
