Abstract: A vehicle-mounted directed advertisement system and method enables a marketing user to configure an advertisement campaign, and display the advertisement, in the form of audio-visual digital content, from a vehicle-mounted electronic display that is driven by a driving user, and directed towards a targeted consumer in a target geographic marketing area. The advertisement is designed by the marketing user and directed towards the targeted consumer through the electronic display. The audio-visual content is stored on a server and communicated to the electronic display. The location of driving user's portable communication device is tracked and generates audio-visual content based on its position relative to a geographic fence marketing perimeter. The driving user is payed to mount the electronic display and navigate through the geographic fence, so as to engage a targeted consumer with the advertisement. A dynamic traffic message displays on the electronic display when a traffic event occurs.
