A number of transit agencies in the greater Baltimore region have overlapping service areas, and as a result some stops are shared between operators and/or networks. Typically what this looks like is multiple signs will be fixed to the same post for the different services, and usually the stop will have a different reference number within the systems it serves. If there is a shelter, it is operated by just one of the agencies that uses the stop.
Locally, the Maryland Transit Administration (MTA) stops are the most thoroughly mapped, and functions as the “primary” operator for the region, with connecting agencies often functioning as supplements to it rather than alternatives. In auditing the bus stop information on the map, I had initially thought adding shared stop information to a highway=bus_stop node would involve using operator namespaces like ref:MTA= so that it is clear which agency uses that stop number. The distinction between a shared stop node and two different stop nodes for overlapping services seems like an important one, as in some cases an overlapping service can have a stop very close to another rather than sharing one. This can make a difference in the logistics of connecting between services or assessing some of the finer details of bus stop placement.
I intend to make a more concerted effort to review Baltimore’s public transit mapping on OSM, but I wanted to document this observation so that I do not forget to work on it after that.
I had been operating under the incorrect assumption that Washington, DC would be more thoroughly mapped than most American cities across the board. That was not a well informed assumption - almost none of the DC area’s transit is on the map.
