The intention of this project is to standardize the list of venue types that represent Digital-Out-of-Home (DOOH) advertising screens within a programmatic OpenRTB 2.5 context. The systematization of DOOH venue types will allow for clearer targeting by media buying platforms across a spectrum of available supply-side platforms offering DOOH inventory.
There are advertising spaces around the escalators in train stations, especially in Europe - i.e. the London Underground.
Proposal: "Transit" > "Trains" > "Escalators"
Definition: Panels placed on the side of escalators throughout the train station.
