A system for displaying information related to a fixed-route transit system collects ads and ad display instructions from advertisers. The advertisers choose one or more zoom levels at which their ads will be displayed, and they specify the stop and/or route on the transit system that the ads will be displayed with. Users of the information system view information related to the fixed-route transit system overlaid on maps, and the ads are shown based on the particular zoom level they are using, one or more stops and/or routes being shown, and/or the one or more routes on which the user is travelling. |
