If any of those services are bus routes, are they highlighted as special, or do they seem like any other bus service?
The Human Transit blog highlights the importance of being very clear which routes have high-quality, frequent service (regardless of technology):
Berlin, for example, presents its system this way:Human Transit calls Berlin's Metro-Nezt a Frequent Network brand.
Obviously the important point here is the Metro-Netz definition, which focuses on the quantity and type of service -- promising local-stop service that runs very frequently all day and evening. Both buses and streetcars/trams can provide this service, and they encourage you to focus on the service, not the technology.
- Rapid transit, consisting of U-bahn and S-bahn. (These have numbers starting with U or S. Both are fully grade separated rail transit. ... )
- Frequent local-stop transit, called the "Metro-Netz." Metro-Netz service is identified by a route number starting with M, and this supposedly guarantees service every 10 minutes or better for 20 hours a day. Metro-Netz service can be either streetcar or bus.
- Less-frequent local-stop transit, which is identified by a route number without an initial letter.
