Interactive Transit Maps

Interactive transit maps in some subway stations use large touchscreen displays for route planning, service alerts, and real-time train positions on a zoomable, pannable map. Interface quality varies so much from city to city that you can tell which transit agencies invested in user testing and which just bought the cheapest kiosk software available. Better versions show estimated travel time for each route option and highlight transfers clearly with color-coded lines and walking time between platforms. Screen size matters. At 46 or 55 inches, the map is large enough for 2 or 3 people to look at simultaneously. Viewing angle means you can read it from a few feet back while others use it up close. Accessibility features on the good ones include high-contrast mode, audio directions through a headphone jack, and text sizing that responds to a pinch gesture. Reliability is the biggest problem. These screens face weather, dust, and constant public use. A broken touchscreen is worse than no screen at all because it trains people to ignore the kiosks entirely. Ideally, this technology would integrate with personal devices so you could send a planned route to your phone and follow it there. Some systems are starting to do that through NFC tap. The physical interface also serves a role phones can't: showing where you are in the station relative to exits, escalators, and platform edges. Spatial orientation is valuable underground where GPS doesn't work. Maps that include neighborhood context above ground, showing landmarks and street names near each exit, answer the question most riders actually have. Not how do I get on the train, but where do I end up when I get off.
