I’m defining a “transit appliance” as a category of devices (not any particular device) that meet two conditions:
- Display transit information (in the current case under discussion, vehicle arrival estimates – but potentially other information as well).
- Are an ‘appliance’ in the sense that they have been configured to perform just this task, i.e., you turn it on and up comes the transit information. A personal computer on which you have to launch a web browser would NOT meet the definition. It needs to “just work”. No mouse, no keyboard. Just a power switch (at least after initial configuration).
I first introduced the idea of a “transit appliance” in this post on Portland Transport.
