Transit advertising is a form of outdoor advertising that places ads on or around public transportation systems. It reaches people while they commute, travel, and move through cities, making it one of the most consistent and high-frequency advertising channels available. Because commuters often follow the same routes every day, transit advertising delivers repeated exposure that builds strong brand recall.

This article explains what transit advertising is, the different formats available, and how businesses use it effectively.
